* procfs.c: Cleanup of procfs tracing.  Move defines and
        prototypes to proc-utils.h
        * proc-utils.h: Define tracing macros.  Declare trace functions.
        * proc-api.c: Make procfs tracing a runtime option.
        (prepare_to_trace): New function, abstracted out of several
        places.  Open a trace file if one is required.
        (ioctl_with_trace, write_with_trace, open_with_trace,
        close_with_trace, wait_with_trace, lseek_with_trace):
        Report errno if an error occurs in a system call.

Michael Snyder 6c1a54b22b 2000-05-05 Michael Snyder <msnyder@seadog.cygnus.com>
* 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.

Peter Schauer b682323727 * procfs.c (proc_set_exec_trap, procfs_init_inferior, procfs_wait,
unconditionally_kill_inferior):  Undo Oct 26 1996 and Apr 26 1997
	changes to trace PRFS_STOPTERM and handle PR_DEAD.
	These changes tried to work around a problem with an early DU 4.0
	release, but they trigger subtle timing dependent kernel bugs
	in older OSF/1 releases.

        exit from an attached process, and cleanup procinfo handles
        when the process exits; (procfs_resume, procfs_wait): cleanup

Geoffrey Noer 234c409626 Mon Apr 14 15:54:51 1997 Geoffrey Noer <noer@pizza.cygnus.com>
* procfs.c (notice_signals): fix typo
1997-04-14 23:06:49 +00:00
Geoffrey Noer 234a732de0 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
1997-04-10 20:24:42 +00:00
Fred Fish 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.

Fred Fish b607efe714 See gdb ChangeLog entry with header:
Thu Jul 25 19:41:31 1996  Fred Fish  <fnf@cygnus.com>

for a rather huge set of changes.  I was going to put them here, but it
made cvs dump core.  :-(
1996-07-26 03:01:51 +00:00
Stu Grossman 9b33e492d6 * procfs.c (procfs_thread_alive procfs_stop): Make static.
* (procfs_pid_to_str):  New routine to print out thread id's in an
	intelligible manner.
	* sol-thread.c (sol_thread_fetch_registers):  Re-order manner in
	which supply_register is called to fix bug with writing writing
	individual regs.
	* config/sparc/tm-sun4sol2.h:  Define default for
	target_pid_to_str in case host lacks libthread_db.
1996-05-15 01:09:57 +00:00
Stu Grossman 47ef0da56a * Makefile.in config.in configure configure.in
config/sparc/nm-sun4sol2.h config/sparc/sun4sol2.mh
	config/sparc/tm-sun4sol2.h:  Use autoconf to config Solaris thread
	and pthread support, since pre-2.5 systems don't come with
	libthread_db.so.1.

	* procfs.c (info_proc):  Use int instead of id_t.  Old versions of
	Irix don't see to define this.
1996-05-14 07:02:56 +00:00
Stu Grossman fdfa331511 * Makefile.in, breakpoint.c, corelow.c, fork-child.c, inflow.c,
infrun.c, mac-nat.c, procfs.c, remote.c, sol-thread.c, thread.c,
	win32-nat.c, config/nm-lynx.h:  Rename thread.h to gdbthread.h to
	avoid conflict with Solaris /usr/include/thread.h.
1996-05-09 21:24:20 +00:00
Stu Grossman 8fc2b4170d * 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.
