/* Machine independent support for SVR4 /proc (process file system) for GDB.
Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com> * procfs.c: Substantial (but incomplete) changes to support sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT. (procfs_notice_signals): now a necessary wrapper around (notice_signals): which are the new guts for noticing signals (open_proc_file): gets a new flag arg used in sysv4.2mp to determine whether or not to attempt to open the ctl_fd. (procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill(). (procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better. Sysv4.2mp and IRIX both have SYS_sproc so the IRIX specific code now also checks it's not UNIXWARE. * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T, HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to "/debug/%d" as PROC_NAME_FMT used to be

Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com> * procfs.c: Substantial (but incomplete) changes to support sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT. (procfs_notice_signals): now a necessary wrapper around (notice_signals): which are the new guts for noticing signals (open_proc_file): gets a new flag arg used in sysv4.2mp to determine whether or not to attempt to open the ctl_fd. (procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill().

Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com> * procfs.c: Substantial (but incomplete) changes to support sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT. (procfs_notice_signals): now a necessary wrapper around (notice_signals): which are the new guts for noticing signals (open_proc_file): gets a new flag arg used in sysv4.2mp to determine whether or not to attempt to open the ctl_fd. (procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill(). (procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better. Sysv4.2mp and IRIX both have SYS_sproc so the IRIX specific code now also checks it's not UNIXWARE. * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T, HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to "/debug/%d" as PROC_NAME_FMT used to be

Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com> * procfs.c: Substantial (but incomplete) changes to support sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT. (procfs_notice_signals): now a necessary wrapper around (notice_signals): which are the new guts for noticing signals (open_proc_file): gets a new flag arg used in sysv4.2mp to determine whether or not to attempt to open the ctl_fd. (procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill(). (procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better. Sysv4.2mp and IRIX both have SYS_sproc so the IRIX specific code now also checks it's not UNIXWARE. * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T, HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to "/debug/%d" as PROC_NAME_FMT used to be

Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT. (procfs_notice_signals): now a necessary wrapper around (notice_signals): which are the new guts for noticing signals (open_proc_file): gets a new flag arg used in sysv4.2mp to determine whether or not to attempt to open the ctl_fd. (procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill().

Implements Solaris thread support. * symfile.c (symbol_file_add): Add call to target_new_objfile to notify target-dependent code about new symbol tables. * (clear_symtab_users): Call target_new_objfile to notify it of the removal of all symbol tables. * target.c (push_target): Make sure that to_close is non-zero before calling it. * target.h (target_new_objfile): Provide default. * config/alpha/nm-osf2.h: Define LOSING_POLL because this version of OSF can't hack using poll with /proc. * config/sparc/nm-sun4sol2.h (target_new_objfile): Define to be sol-thread-new-objfile. * config/sparc/sun4sol2.mh: Add sol-thread.o to NATDEFFILES, and add libthread_db.so.1 to NAT_CLIBS. * config/sparc/tm-sun4sol2.h: Define PIDGET, TIDGET, and target_pid_to_str.

The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing.

Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better.

The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not.

(procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better.

Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com> * procfs.c: Substantial (but incomplete) changes to support sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT. (procfs_notice_signals): now a necessary wrapper around (notice_signals): which are the new guts for noticing signals (open_proc_file): gets a new flag arg used in sysv4.2mp to determine whether or not to attempt to open the ctl_fd. (procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill(). (procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better. Sysv4.2mp and IRIX both have SYS_sproc so the IRIX specific code now also checks it's not UNIXWARE. * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T, HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to "/debug/%d" as PROC_NAME_FMT used to be

Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com> * procfs.c: Substantial (but incomplete) changes to support sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT. (procfs_notice_signals): now a necessary wrapper around (notice_signals): which are the new guts for noticing signals (open_proc_file): gets a new flag arg used in sysv4.2mp to determine whether or not to attempt to open the ctl_fd. (procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill(). (procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better.

Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com> * procfs.c: Substantial (but incomplete) changes to support sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT. (procfs_notice_signals): now a necessary wrapper around (notice_signals): which are the new guts for noticing signals (open_proc_file): gets a new flag arg used in sysv4.2mp to determine whether or not to attempt to open the ctl_fd.

DESCRIPTION
Store our current register values back into the inferior. If
REGNO is -1 then store all the register, otherwise store just
the value specified by REGNO.
NOTES
If we are storing only a single register, we first have to get all
the current values from the process, overwrite the desired register
in the gregset with the one we want from gdb's registers, and then
send the whole set back to the process. For writing all the
registers, all we have to do is generate the gregset and send it to
the process.
Also note that the process has to be stopped on an event of interest
for this to work, which basically means that it has to have been
run under the control of one of the other /proc ioctl calls and not
ptrace. Since we don't use ptrace anyway, we don't worry about this
fine point, but it is worth noting for future reference.
Gdb is confused about what this function is supposed to return.
Some versions return a value, others return nothing. Some are
declared to return a value and actually return nothing. Gdb ignores
anything returned. (FIXME)
*/
Make the /proc support a target-struct in its own right. * inferior.h (proc_wait, inferior_proc_init, proc_set_exec_trap): No longer global functions. (fork_inferior): New global function from fork-child.c. * inftarg.c (child_wait): Remove USE_PROC_FS conditional. (ptrace_me, ptrace_him): New stub functions for fork_inferior(). (child_create_inferior): Moved to fork-child.c as fork_inferior. (child_create_inferior): New tiny function that calls fork_inferior. * fork-child.c: New file, containing fork_inferior, which is built from slight mods to inftarg.c's child_create_inferior. * procfs.c (procfs_ops): Add target vector. (attach): Rename as static do_attach. (procfs_create_inferior): New tiny function that calls fork_inferior. (child_xfer_memory): Rename to static procfs_xfer_memory. (store_inferior_registers): Rename to static procfs_store_registers. (inferior_proc_init): Rename to static procfs_init_inferior. (procfs_attach, procfs_detach, procfs_prepare_to_store, procfs_files_info, procfs_open, procfs_mourn_inferior, procfs_can_run): Slightly mangled copies of the corresponding child_XXX routines from inftarg.c. (proc_wait): Renamed to static procfs_wait. (child_resume): Rename to static procfs_resume. (fetch_inferior_registers): Rename to static procfs_fetch_registers. (initialize_proc_fs): Rename to initialize_procfs. Set up procfs_ops, too. * xm-irix4.h, xm-sysv4.h (CREATE_INFERIOR_HOOK): No longer needed.

The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not.

(procfs_notice_signals): now a necessary wrapper around (notice_signals): which are the new guts for noticing signals (open_proc_file): gets a new flag arg used in sysv4.2mp to determine whether or not to attempt to open the ctl_fd. (procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill(). (procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better. Sysv4.2mp and IRIX both have SYS_sproc so the IRIX specific code now also checks it's not UNIXWARE. * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T, HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to "/debug/%d" as PROC_NAME_FMT used to be

Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com> * procfs.c: Substantial (but incomplete) changes to support sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT. (procfs_notice_signals): now a necessary wrapper around (notice_signals): which are the new guts for noticing signals (open_proc_file): gets a new flag arg used in sysv4.2mp to determine whether or not to attempt to open the ctl_fd. (procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill(). (procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better. Sysv4.2mp and IRIX both have SYS_sproc so the IRIX specific code now also checks it's not UNIXWARE. * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T, HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to "/debug/%d" as PROC_NAME_FMT used to be

The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not.

(procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill(). (procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better. Sysv4.2mp and IRIX both have SYS_sproc so the IRIX specific code now also checks it's not UNIXWARE. * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T, HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to "/debug/%d" as PROC_NAME_FMT used to be

DESCRIPTION
Allocate a procinfo structure, open the /proc file and then set up the
set of signals and faults that are to be traced. Returns a pointer to
the new procinfo structure.
NOTES
If proc_init_failed ever gets called, control returns to the command
processing loop via the standard error handling code.

LOCAL FUNCTION
procfs_exit_handler - handle entry into the _exit syscall
SYNOPSIS
int procfs_exit_handler (pi, syscall_num, why, rtnvalp, statvalp)
DESCRIPTION
This routine is called when an inferior process enters the _exit()
system call. It continues the process, and then collects the exit
status and pid which are returned in *statvalp and *rtnvalp. After
that it returns non-zero to indicate that procfs_wait should wake up.
NOTES
There is probably a better way to do this.

This routine is called when an inferior process is about to finish any

This need for compatibility with ptrace is questionable. In the

DESCRIPTION
This routine is called when an inferior process is about to finish an

a lightweight process. When the target process gets this event, we can
look at rval1 to find the new child processes ID, and create a new
procinfo struct from that.
After that, it pretends that we got a SIGTRAP, and returns non-zero

woken up, sees the new process and continues it.

We actually never see the child exiting from sproc because we will
shortly stop the child with PIOCSTOP, which is then registered as the
event of interest.

This routine is called when an inferior process is about to finish a

This is necessary for IRIX because we have to set PR_FORK in order
to catch the creation of lwps (via sproc()). When an actual fork
occurs, it becomes necessary to reset the forks debugger flags and
continue it because we can't hack multiple processes yet.

Called for each "procinfo" (process, thread, or LWP) in the
inferior, to register for notification of and handlers for
syscall traps in the inferior.
Many changes to procfs.c, mostly to expand the "info proc" command and to fix a couple of small bugs. Changes to other files mostly to fix minor things pointed out by the SGI compiler. See ChangeLog for complete details.
1992-04-01 19:46:14 +00:00
New files for DWARF debugging format support, ELF object file support, SVR4 /proc (process file system) support, Amiga UNIX target and host defines, SVR4 target and host defines, and m68k hosts defines.

Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com> * procfs.c: Substantial (but incomplete) changes to support sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT. (procfs_notice_signals): now a necessary wrapper around (notice_signals): which are the new guts for noticing signals (open_proc_file): gets a new flag arg used in sysv4.2mp to determine whether or not to attempt to open the ctl_fd. (procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill(). (procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better. Sysv4.2mp and IRIX both have SYS_sproc so the IRIX specific code now also checks it's not UNIXWARE. * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T, HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to "/debug/%d" as PROC_NAME_FMT used to be

LOCAL FUNCTION
procfs_init_inferior - initialize target vector and access to a
/proc entry
SYNOPSIS
int procfs_init_inferior (int pid)
DESCRIPTION
When gdb starts an inferior, this function is called in the parent
process immediately after the fork. It waits for the child to stop
on the return from the exec system call (the child itself takes care
of ensuring that this is set up), then sets up the set of signals
and faults that are to be traced. Returns the pid, which may have had
the thread-id added to it.
NOTES
If proc_init_failed ever gets called, control returns to the command
processing loop via the standard error handling code.

DESCRIPTION
When the user changes the state of gdb's signal handling via the
"handle" command, this function gets called to see if any change
in the /proc interface is required. It is also called internally
by other /proc interface functions to initialize the state of
the traced signal set.
One thing it does is that signals for which the state is "nostop",
"noprint", and "pass", have their trace bits reset in the pr_trace
field, so that they are no longer traced. This allows them to be
delivered directly to the inferior without the debugger ever being
involved.

proc_set_exec_trap -- arrange for exec'd child to halt at startup
SYNOPSIS
void proc_set_exec_trap (void)
DESCRIPTION
This function is called in the child process when starting up
an inferior, prior to doing the exec of the actual inferior.
It sets the child process's exitset to make exit from the exec
system call an event of interest to stop on, and then simply
returns. The child does the exec, the system call returns, and
the child stops at the first instruction, ready for the gdb
parent process to take control of it.
NOTE
We need to use all local variables since the child may be sharing
it's data space with the parent, if vfork was used rather than
fork.
Many changes to procfs.c, mostly to expand the "info proc" command and to fix a couple of small bugs. Changes to other files mostly to fix minor things pointed out by the SGI compiler. See ChangeLog for complete details.

Change the stream argument to _filtered to GDB_FILE *. Change all references to stdout/stderr to gdb_stdout/gdb_stderr. Replace all calls to stdio output functions with calls to corresponding _unfiltered functions (`fprintf_unfiltered') Replaced calls to fopen for output to gdb_fopen. Added sufficient goo to utils.c and defs.h to make the above work. The net effect is that stdio output functions are only directly used in utils.c. Elsewhere, the _unfiltered and _filtered functions and GDB_FILE type are used. In the near future, GDB_FILE will stop being equivalant to FILE. The semantics of some commands has changed in a very subtle way: called in the right context, they may cause new occurences of prompt_for_continue() behavior. The testsuite doesn't notice anything like this, though. Please respect this change by not reintroducing stdio output dependencies in the main body of gdb code. All output from commands should go to a GDB_FILE. Target-specific code can still use stdio directly to communicate with targets.

Change the stream argument to _filtered to GDB_FILE *. Change all references to stdout/stderr to gdb_stdout/gdb_stderr. Replace all calls to stdio output functions with calls to corresponding _unfiltered functions (`fprintf_unfiltered') Replaced calls to fopen for output to gdb_fopen. Added sufficient goo to utils.c and defs.h to make the above work. The net effect is that stdio output functions are only directly used in utils.c. Elsewhere, the _unfiltered and _filtered functions and GDB_FILE type are used. In the near future, GDB_FILE will stop being equivalant to FILE. The semantics of some commands has changed in a very subtle way: called in the right context, they may cause new occurences of prompt_for_continue() behavior. The testsuite doesn't notice anything like this, though. Please respect this change by not reintroducing stdio output dependencies in the main body of gdb code. All output from commands should go to a GDB_FILE. Target-specific code can still use stdio directly to communicate with targets.

Change the stream argument to _filtered to GDB_FILE *. Change all references to stdout/stderr to gdb_stdout/gdb_stderr. Replace all calls to stdio output functions with calls to corresponding _unfiltered functions (`fprintf_unfiltered') Replaced calls to fopen for output to gdb_fopen. Added sufficient goo to utils.c and defs.h to make the above work. The net effect is that stdio output functions are only directly used in utils.c. Elsewhere, the _unfiltered and _filtered functions and GDB_FILE type are used. In the near future, GDB_FILE will stop being equivalant to FILE. The semantics of some commands has changed in a very subtle way: called in the right context, they may cause new occurences of prompt_for_continue() behavior. The testsuite doesn't notice anything like this, though. Please respect this change by not reintroducing stdio output dependencies in the main body of gdb code. All output from commands should go to a GDB_FILE. Target-specific code can still use stdio directly to communicate with targets.

GLOBAL FUNCTION
proc_base_address -- find base address for segment containing address
SYNOPSIS
CORE_ADDR proc_base_address (CORE_ADDR addr)
DESCRIPTION
Given an address of a location in the inferior, find and return
the base address of the mapped segment containing that address.
This is used for example, by the shared library support code,
where we have the pc value for some location in the shared library
where we are stopped, and need to know the base address of the
segment containing that address.

DESCRIPTION
Given an address in the current inferior's address space, use the
/proc interface to find an open file descriptor for the file that
this address was mapped in from. Return -1 if there is no current
inferior. Print a warning message if there is an inferior but
the address corresponds to no file (IE a bogus address).

Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com> * procfs.c: Substantial (but incomplete) changes to support sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT. (procfs_notice_signals): now a necessary wrapper around (notice_signals): which are the new guts for noticing signals (open_proc_file): gets a new flag arg used in sysv4.2mp to determine whether or not to attempt to open the ctl_fd. (procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill(). (procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better. Sysv4.2mp and IRIX both have SYS_sproc so the IRIX specific code now also checks it's not UNIXWARE. * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T, HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to "/debug/%d" as PROC_NAME_FMT used to be

DESCRIPTION
Attach to an already existing process with the specified process
id. If the process is not already stopped, query whether to
stop it or not.
NOTES
The option of stopping at attach time is specific to the /proc
versions of gdb. Versions using ptrace force the attachee
* buildsym.c (finish_block): Fix thinko `inner block' complaints. * dbxread.c (process_one_symbol): Parse N_OPT "gcc2_compiled.". * procfs.c (proc_set_exec_trap): Set run-on-last-close flag on child processes, to avoid dead ones "hanging around" after GDB exits. (attach): Always stop the process if it needs it. Set RLC flag when attaching running processes, so it will continue if we detach it, quit, or are killed. (detach): Clear faults and set RLC flag to make process run when we close it. (open_proc_file): New `mode' argument for O_RDONLY or O_RDWR. Callers changed. (info_proc): Open process O_RDONLY, so we can see any process, even those controlled by debuggers. * tm-sun4sol2.h (SUN_FIXED_LBRAC_BUG): They did (in Sol 2).

Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com> * procfs.c: Substantial (but incomplete) changes to support sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT. (procfs_notice_signals): now a necessary wrapper around (notice_signals): which are the new guts for noticing signals (open_proc_file): gets a new flag arg used in sysv4.2mp to determine whether or not to attempt to open the ctl_fd. (procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill(). (procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better. Sysv4.2mp and IRIX both have SYS_sproc so the IRIX specific code now also checks it's not UNIXWARE. * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T, HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to "/debug/%d" as PROC_NAME_FMT used to be

DESCRIPTION
Detach from the current attachee.
If signal is non-zero, the attachee is started running again and sent
the specified signal.
If signal is zero and the attachee was not already stopped when we
attached to it, then we make it runnable again when we detach.
Otherwise, we query whether or not to make the attachee runnable
again, since we may simply want to leave it in the state it was in
when we attached.
We report any problems, but do not consider them errors, since we
MUST detach even if some things don't seem to go right. This may not
be the ideal situation. (FIXME).

Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com> * procfs.c: Substantial (but incomplete) changes to support sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT. (procfs_notice_signals): now a necessary wrapper around (notice_signals): which are the new guts for noticing signals (open_proc_file): gets a new flag arg used in sysv4.2mp to determine whether or not to attempt to open the ctl_fd. (procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill(). (procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better.

Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing.

Add procfs support for Alpha OSF/1-2.x. * config/alpha/nm-osf.h: Renamed from nm-alpha.h, generic OSF/1 native support. * config/alpha/alpha-osf1.mh (NAT_FILE): Changed accordingly. (MUNCH_DEFINE): Removed. * config/alpha/alpha-osf2.mh, config/alpha/nm-osf2.h: New files for procfs support. * configure.in (alpha-dec-osf*): Use alpha-osf2.mh for OSF/1 release 2.x and higher, else alpha-osf1.mh, as the procfs support in release 1.x is incomplete. * Makefile.in (ALLCONFIG): Add config/alpha/alpha-osf2.mh. * alpha-nat.c (supply_gregset, fill_gregset, supply_fpgregset, fill_fpgregset): New routines for procfs support. * inftarg.c (_initialize_inftarg): Don't add ptrace support if we have an optional procfs and /proc is accessible. * procfs.c: Include sys/fault.h and sys/syscall.h before including sys/procfs.h. (unconditionally_kill_inferior): If PROCFS_NEED_PIOCSSIG_FOR_KILL is defined, additionally perform a PIOCSSIG to really terminate the inferior. (create_procinfo): Always return a result. (create_procinfo, do_attach): Don't trace T_IFAULT faults if PROCFS_DONT_TRACE_IFAULT is defined. (procfs_init_inferior): Use START_INFERIOR_TRAPS_EXPECTED as argument to startup_inferior if it is defined. (proc_set_exec_trap): If PIOCSSPCACT is defined, use it instead of tracing exits from exec system calls. Needed for the user level loader under Alpha OSF/1. (do_detach): Clear any pending signal if we want to detach from a process without a signal. (set_proc_siginfo): If PROCFS_DONT_PIOCSSIG_CURSIG is defined, don't issue a PIOCSSIG if pr_cursig already contains the signal we intend to set. (info_proc_signals): If PROCFS_SIGPEND_OFFSET is defined, the pending signals are numbered from 1 instead of 0. (info_proc_mappings): Increase size of output format for addresses if BFD_HOST_64_BIT is defined. (procfs_stop): Renamed from child_stop. (_initialize_procfs): Don't add procfs support if we have an optional procfs and /proc is not accessible.

/* emulate wait() as much as possible.
Wait for child to do something. Return pid of child, or -1 in case
of error; store status in *OURSTATUS.
Not sure why we can't
just use wait(), but it seems to have problems when applied to a
process being controlled with the /proc interface.
We have a race problem here with no obvious solution. We need to let
the inferior run until it stops on an event of interest, which means
that we need to use the PIOCWSTOP ioctl. However, we cannot use this
ioctl if the process is already stopped on something that is not an
event of interest, or the call will hang indefinitely. Thus we first
use PIOCSTATUS to see if the process is not stopped. If not, then we
use PIOCWSTOP. But during the window between the two, if the process
stops for any reason that is not an event of interest (such as a job
control signal) then gdb will hang. One possible workaround is to set
an alarm to wake up every minute of so and check to see if the process
is still running, and if so, then reissue the PIOCWSTOP. But this is
a real kludge, so has not been implemented. FIXME: investigate
alternatives.

being control by /proc routines. */

The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT.

(procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better. Sysv4.2mp and IRIX both have SYS_sproc so the IRIX specific code now also checks it's not UNIXWARE. * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T, HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to "/debug/%d" as PROC_NAME_FMT used to be

Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com> * procfs.c: Substantial (but incomplete) changes to support sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT. (procfs_notice_signals): now a necessary wrapper around (notice_signals): which are the new guts for noticing signals (open_proc_file): gets a new flag arg used in sysv4.2mp to determine whether or not to attempt to open the ctl_fd. (procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill(). (procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better. Sysv4.2mp and IRIX both have SYS_sproc so the IRIX specific code now also checks it's not UNIXWARE. * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T, HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to "/debug/%d" as PROC_NAME_FMT used to be

The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT. (procfs_notice_signals): now a necessary wrapper around (notice_signals): which are the new guts for noticing signals (open_proc_file): gets a new flag arg used in sysv4.2mp to determine whether or not to attempt to open the ctl_fd. (procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill(). (procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better. Sysv4.2mp and IRIX both have SYS_sproc so the IRIX specific code now also checks it's not UNIXWARE. * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T, HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to "/debug/%d" as PROC_NAME_FMT used to be

LOCAL FUNCTION
set_proc_siginfo - set a process's current signal info
SYNOPSIS
void set_proc_siginfo (struct procinfo *pip, int signo);
DESCRIPTION
Given a pointer to a process info struct in PIP and a signal number
in SIGNO, set the process's current signal and its associated signal
information. The signal will be delivered to the process immediately
after execution is resumed, even if it is being held. In addition,
this particular delivery will not cause another PR_SIGNALLED stop
even if the signal is being traced.
If we are not delivering the same signal that the prstatus siginfo
struct contains information about, then synthesize a siginfo struct
to match the signal we are doing to deliver, make it of the type
"generated by a user process", and send this synthesized copy. When
used to set the inferior's signal state, this will be required if we
are not currently stopped because of a traced signal, or if we decide
to continue with a different signal.
Note that when continuing the inferior from a stop due to receipt
of a traced signal, we either have set PRCSIG to clear the existing
signal, or we have to call this function to do a PIOCSSIG with either
the existing siginfo struct from pr_info, or one we have synthesized
appropriately for the signal we want to deliver. Otherwise if the
signal is still being traced, the inferior will immediately stop
again.
See siginfo(5) for more details.

The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT.

(procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill(). (procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better. Sysv4.2mp and IRIX both have SYS_sproc so the IRIX specific code now also checks it's not UNIXWARE. * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T, HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to "/debug/%d" as PROC_NAME_FMT used to be

* README: Add note about SPARCworks cc release 3.0 and higher. Add procfs support for Alpha OSF/1-2.x. * config/alpha/nm-osf.h: Renamed from nm-alpha.h, generic OSF/1 native support. * config/alpha/alpha-osf1.mh (NAT_FILE): Changed accordingly. (MUNCH_DEFINE): Removed. * config/alpha/alpha-osf2.mh, config/alpha/nm-osf2.h: New files for procfs support. * configure.in (alpha-dec-osf*): Use alpha-osf2.mh for OSF/1 release 2.x and higher, else alpha-osf1.mh, as the procfs support in release 1.x is incomplete. * Makefile.in (ALLCONFIG): Add config/alpha/alpha-osf2.mh. * alpha-nat.c (supply_gregset, fill_gregset, supply_fpgregset, fill_fpgregset): New routines for procfs support. * inftarg.c (_initialize_inftarg): Don't add ptrace support if we have an optional procfs and /proc is accessible. * procfs.c: Include sys/fault.h and sys/syscall.h before including sys/procfs.h. (unconditionally_kill_inferior): If PROCFS_NEED_PIOCSSIG_FOR_KILL is defined, additionally perform a PIOCSSIG to really terminate the inferior. (create_procinfo): Always return a result. (create_procinfo, do_attach): Don't trace T_IFAULT faults if PROCFS_DONT_TRACE_IFAULT is defined. (procfs_init_inferior): Use START_INFERIOR_TRAPS_EXPECTED as argument to startup_inferior if it is defined. (proc_set_exec_trap): If PIOCSSPCACT is defined, use it instead of tracing exits from exec system calls. Needed for the user level loader under Alpha OSF/1. (do_detach): Clear any pending signal if we want to detach from a process without a signal. (set_proc_siginfo): If PROCFS_DONT_PIOCSSIG_CURSIG is defined, don't issue a PIOCSSIG if pr_cursig already contains the signal we intend to set. (info_proc_signals): If PROCFS_SIGPEND_OFFSET is defined, the pending signals are numbered from 1 instead of 0. (info_proc_mappings): Increase size of output format for addresses if BFD_HOST_64_BIT is defined. (procfs_stop): Renamed from child_stop. (_initialize_procfs): Don't add procfs support if we have an optional procfs and /proc is not accessible.

Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing.

under the debugger, it should do nothing (as if the program had
been stopped and then later resumed. Under ptrace, this

the process, and wait_for_inferior would have no way of

Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com> * procfs.c: Substantial (but incomplete) changes to support sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT. (procfs_notice_signals): now a necessary wrapper around (notice_signals): which are the new guts for noticing signals (open_proc_file): gets a new flag arg used in sysv4.2mp to determine whether or not to attempt to open the ctl_fd. (procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill(). (procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better. Sysv4.2mp and IRIX both have SYS_sproc so the IRIX specific code now also checks it's not UNIXWARE. * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T, HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to "/debug/%d" as PROC_NAME_FMT used to be

close_proc_file - close any currently open /proc entry
SYNOPSIS
Many small changes to procfs.c to add base support for a new "info proc" command that prints /proc specific information, changes to solib.c to allow more flexible handling of finding the dynamic linker structures, changes to utils.c and defs.h to add a new null_cleanup() function to serve as an anchor point for cleanup chains with no obvious "first cleanup".

DESCRIPTION
Close any currently open /proc entry and mark the process information
entry as invalid. In order to ensure that we don't try to reuse any
stale information, the pid, fd, and pathnames are explicitly
invalidated, which may be overkill.

DESCRIPTION
* buildsym.c (finish_block): Fix thinko `inner block' complaints. * dbxread.c (process_one_symbol): Parse N_OPT "gcc2_compiled.". * procfs.c (proc_set_exec_trap): Set run-on-last-close flag on child processes, to avoid dead ones "hanging around" after GDB exits. (attach): Always stop the process if it needs it. Set RLC flag when attaching running processes, so it will continue if we detach it, quit, or are killed. (detach): Clear faults and set RLC flag to make process run when we close it. (open_proc_file): New `mode' argument for O_RDONLY or O_RDWR. Callers changed. (info_proc): Open process O_RDONLY, so we can see any process, even those controlled by debuggers. * tm-sun4sol2.h (SUN_FIXED_LBRAC_BUG): They did (in Sol 2).

Given a process id and a mode, close the existing open /proc
entry (if any) and open one for the new process id, in the
specified mode. Once it is open, then mark the local process
information structure as valid, which guarantees that the pid,
fd, and pathname fields match an open /proc entry. Returns
zero if the open fails, nonzero otherwise.

1991-10-24 11:28:54 +00:00
Note that the pathname is left intact, even when the open fails,
so that callers can use it to construct meaningful error messages
rather than just "file open failed".
* fork-child.c (fork_inferior), inferior.h: init_trace_fun now returns a possibly modified pid. * inftarg.c (ptrace_him): Now returns pid; * m3-nat.c (m3_trace_him): Now returns pid; * infcmd.c (run_command): Minor cleanup. * infrun.c (wait_for_inferior): Add another check for one_stepped near where we read the pc to avoid erroneously setting random_signal for multi-threaded support. * procfs.c: Add support for Solaris LWPs. Remove def of LOSING_POLL. Many cleanups... Several workarounds for Solaris lossage. System call entry and exit are now handled by dynamically registered handlers. * (syscallname): Don't barf when handed an unknown syscall number. * (info_proc_syscalls): Ditto. * sol-thread.c: New file. Implements Solaris thread support. * symfile.c (symbol_file_add): Add call to target_new_objfile to notify target-dependent code about new symbol tables. * (clear_symtab_users): Call target_new_objfile to notify it of the removal of all symbol tables. * target.c (push_target): Make sure that to_close is non-zero before calling it. * target.h (target_new_objfile): Provide default. * config/alpha/nm-osf2.h: Define LOSING_POLL because this version of OSF can't hack using poll with /proc. * config/sparc/nm-sun4sol2.h (target_new_objfile): Define to be sol-thread-new-objfile. * config/sparc/sun4sol2.mh: Add sol-thread.o to NATDEFFILES, and add libthread_db.so.1 to NAT_CLIBS. * config/sparc/tm-sun4sol2.h: Define PIDGET, TIDGET, and target_pid_to_str.
1996-05-06 21:27:37 +00:00
Note that for Solaris, the process-id also includes an LWP-id, so we
actually attempt to open that. If we are handed a pid with a 0 LWP-id,
then we will ask the kernel what it is and add it to the pid. Hence,
the pid can be changed by us.

Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com> * procfs.c: Substantial (but incomplete) changes to support sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT. (procfs_notice_signals): now a necessary wrapper around (notice_signals): which are the new guts for noticing signals (open_proc_file): gets a new flag arg used in sysv4.2mp to determine whether or not to attempt to open the ctl_fd. (procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill(). (procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better. Sysv4.2mp and IRIX both have SYS_sproc so the IRIX specific code now also checks it's not UNIXWARE. * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T, HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to "/debug/%d" as PROC_NAME_FMT used to be

Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com> * procfs.c: Substantial (but incomplete) changes to support sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT. (procfs_notice_signals): now a necessary wrapper around (notice_signals): which are the new guts for noticing signals (open_proc_file): gets a new flag arg used in sysv4.2mp to determine whether or not to attempt to open the ctl_fd. (procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill(). (procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better. Sysv4.2mp and IRIX both have SYS_sproc so the IRIX specific code now also checks it's not UNIXWARE. * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T, HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to "/debug/%d" as PROC_NAME_FMT used to be

Implement gdb's "info proc" command by using the /proc interface
to print status information about any currently running process.
Examples of the use of "info proc" are:

The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT.

(procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better. Sysv4.2mp and IRIX both have SYS_sproc so the IRIX specific code now also checks it's not UNIXWARE. * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T, HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to "/debug/%d" as PROC_NAME_FMT used to be

The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing.

(procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill(). (procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better. Sysv4.2mp and IRIX both have SYS_sproc so the IRIX specific code now also checks it's not UNIXWARE. * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T, HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to "/debug/%d" as PROC_NAME_FMT used to be

Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com> * procfs.c: Substantial (but incomplete) changes to support sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT. (procfs_notice_signals): now a necessary wrapper around (notice_signals): which are the new guts for noticing signals (open_proc_file): gets a new flag arg used in sysv4.2mp to determine whether or not to attempt to open the ctl_fd. (procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill(). (procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better. Sysv4.2mp and IRIX both have SYS_sproc so the IRIX specific code now also checks it's not UNIXWARE. * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T, HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to "/debug/%d" as PROC_NAME_FMT used to be

The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT. (procfs_notice_signals): now a necessary wrapper around (notice_signals): which are the new guts for noticing signals (open_proc_file): gets a new flag arg used in sysv4.2mp to determine whether or not to attempt to open the ctl_fd. (procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill(). (procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better. Sysv4.2mp and IRIX both have SYS_sproc so the IRIX specific code now also checks it's not UNIXWARE. * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T, HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to "/debug/%d" as PROC_NAME_FMT used to be

Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com> * procfs.c: Substantial (but incomplete) changes to support sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT. (procfs_notice_signals): now a necessary wrapper around (notice_signals): which are the new guts for noticing signals (open_proc_file): gets a new flag arg used in sysv4.2mp to determine whether or not to attempt to open the ctl_fd. (procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill(). (procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better. Sysv4.2mp and IRIX both have SYS_sproc so the IRIX specific code now also checks it's not UNIXWARE. * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T, HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to "/debug/%d" as PROC_NAME_FMT used to be

LOCAL FUNCTION
procfs_lwp_creation_handler - handle exit from the _lwp_create syscall
SYNOPSIS
int procfs_lwp_creation_handler (pi, syscall_num, why, rtnvalp, statvalp)
DESCRIPTION
This routine is called both when an inferior process and it's new lwp
are about to finish a _lwp_create() system call. This is the system
call that Solaris uses to create a lightweight process. When the
target process gets this event, we can look at sysarg[2] to find the
new childs lwp ID, and create a procinfo struct from that. After that,
we pretend that we got a SIGTRAP, and return non-zero to tell
procfs_wait to wake up. Subsequently, wait_for_inferior gets woken up,
sees the new process and continues it.
When we see the child exiting from lwp_create, we just contine it,
since everything was handled when the parent trapped.
NOTES
In effect, we are only paying attention to the parent's completion of
the lwp_create syscall. If we only paid attention to the child
instead, then we wouldn't detect the creation of a suspended thread.

The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing.

(whether the exec has succeeded is stored at that time in the
carry bit or some such architecture-specific and

So I can't think of anything better than to search the PATH
now. This has several disadvantages: (1) There is a race
condition; if we find a file now and it is deleted before we
exec it, we lose, even if the deletion leaves a valid file
further down in the PATH, (2) there is no way to know exactly
what an executable (in the sense of "capable of being

The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not.

(procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better.

#ifdef HAVE_OPTIONAL_PROC_FS
Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com> * procfs.c: Substantial (but incomplete) changes to support sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT. (procfs_notice_signals): now a necessary wrapper around (notice_signals): which are the new guts for noticing signals (open_proc_file): gets a new flag arg used in sysv4.2mp to determine whether or not to attempt to open the ctl_fd. (procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill(). (procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better. Sysv4.2mp and IRIX both have SYS_sproc so the IRIX specific code now also checks it's not UNIXWARE. * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T, HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to "/debug/%d" as PROC_NAME_FMT used to be

Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com> * procfs.c: Substantial (but incomplete) changes to support sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT. (procfs_notice_signals): now a necessary wrapper around (notice_signals): which are the new guts for noticing signals (open_proc_file): gets a new flag arg used in sysv4.2mp to determine whether or not to attempt to open the ctl_fd. (procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill(). (procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better. Sysv4.2mp and IRIX both have SYS_sproc so the IRIX specific code now also checks it's not UNIXWARE. * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T, HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to "/debug/%d" as PROC_NAME_FMT used to be

* README: Add note about SPARCworks cc release 3.0 and higher. Add procfs support for Alpha OSF/1-2.x. * config/alpha/nm-osf.h: Renamed from nm-alpha.h, generic OSF/1 native support. * config/alpha/alpha-osf1.mh (NAT_FILE): Changed accordingly. (MUNCH_DEFINE): Removed. * config/alpha/alpha-osf2.mh, config/alpha/nm-osf2.h: New files for procfs support. * configure.in (alpha-dec-osf*): Use alpha-osf2.mh for OSF/1 release 2.x and higher, else alpha-osf1.mh, as the procfs support in release 1.x is incomplete. * Makefile.in (ALLCONFIG): Add config/alpha/alpha-osf2.mh. * alpha-nat.c (supply_gregset, fill_gregset, supply_fpgregset, fill_fpgregset): New routines for procfs support. * inftarg.c (_initialize_inftarg): Don't add ptrace support if we have an optional procfs and /proc is accessible. * procfs.c: Include sys/fault.h and sys/syscall.h before including sys/procfs.h. (unconditionally_kill_inferior): If PROCFS_NEED_PIOCSSIG_FOR_KILL is defined, additionally perform a PIOCSSIG to really terminate the inferior. (create_procinfo): Always return a result. (create_procinfo, do_attach): Don't trace T_IFAULT faults if PROCFS_DONT_TRACE_IFAULT is defined. (procfs_init_inferior): Use START_INFERIOR_TRAPS_EXPECTED as argument to startup_inferior if it is defined. (proc_set_exec_trap): If PIOCSSPCACT is defined, use it instead of tracing exits from exec system calls. Needed for the user level loader under Alpha OSF/1. (do_detach): Clear any pending signal if we want to detach from a process without a signal. (set_proc_siginfo): If PROCFS_DONT_PIOCSSIG_CURSIG is defined, don't issue a PIOCSSIG if pr_cursig already contains the signal we intend to set. (info_proc_signals): If PROCFS_SIGPEND_OFFSET is defined, the pending signals are numbered from 1 instead of 0. (info_proc_mappings): Increase size of output format for addresses if BFD_HOST_64_BIT is defined. (procfs_stop): Renamed from child_stop. (_initialize_procfs): Don't add procfs support if we have an optional procfs and /proc is not accessible.
