Wrap the sim_resume call in a SIGINT handler. (gdb_os_poll_quit): New function. Check for a quit pending on the console. start-sanitize-gdbtk Wed Apr 16 12:33:06 1997 Andrew Cagney * Makefile.in (install-only): Make list of gdbtcl files to install explicit - was picking up files such as ChangeLog etc. (install-only): Don't blindly create the directory. end-sanitize-gdbtk Thu Apr 17 14:30:04 1997 Per Bothner * defs.h (enum language): Add language_java. * java-exp.y, java-lang.c, java-lang.h, java-valprint.c: New files. * Makefile.in: Update for new files. * objfiles.c (allocate_objfile): Allow NULL bfd argument. * symfile.c (deduce_language_from_filename): Recognize .java.

Mon Apr 14 17:06:27 1997 Mark Alexander * remote-mips.c (mips_load): Ensure that PC gets updated after a load on LSI target.

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 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com) * mn10300-tdep.c: Almost completely rewritten based on mn10200 port. * config/mn10300/tm-mn10300.h: Likewise.
