* procfs.c (many functions): change int cmd; to long cmd;
        Solaris /proc API calls this parameter a long, and requires it
        for 64-bit hosts (where sizeof(long) != sizeof(int)).  UnixWare
        calls it an int, but on existing UnixWare hosts, int and long
        are the same size.  So long it must be.  If a future UnixWare
        version has problems with this, we'll have to use autoconf.
        * proc-api.c (write_with_trace): use long instead of int.

        * infrun.c (wait_for_inferior): Don't add signalled processes
        as new threads.
        * procfs.c (wait_fd): Note if LWP has exited.

NOTE:  I didn't commit Kean's changes to configure.host/configure.tgt
yet because they are kind of bogus and I'm punting back to him to let
him figure out what he's trying to do.  So configuring for UnixWare
may not work just yet.

	changes to trace PRFS_STOPTERM and handle PR_DEAD.
	These changes tried to work around a problem with an early DU 4.0

* 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

e172af811a From Peter Schauer <Peter.Schauer@Regent.E-Technik.TU-Muenchen.DE>
* procfs.c (wait_fd):  Handle EINTR error return from poll
        by restarting the poll.
	* defs.h (PIDGET): Define a default version that just
	returns its argument unchanged.
	* inflow.c (terminal_init_inferior): Eliminate #ifdef
	of PIDGET and fold both alternatives into common code.
	(pass_signal): Use PIDGET for pid passed to kill().
1996-11-16 06:58:43 +00:00
Peter Schauer
1cb1b16cfb * procfs.c (proc_set_exec_trap): Under Alpha OSF/1-4.0, tracing
the entry to the exit system call to detect termination of the
	inferior stopped working. Trace termination of the inferior via
	PRFS_STOPTERM instead.
	(procfs_init_inferior):  Do not trace entry to exit system call
	if PIOCSSPCACT is defined.
	(procfs_wait):  Handle PR_DEAD event, which signals the termination
	of the inferior if PRFS_STOPTERM is set.

	* mdebugread.c (parse_partial_symbols):  Ignore stNil section
	start address symbols.

	* sparc-tdep.c (get_saved_register):  Get saved PC from the
	frame info if not in innermost frame.
