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().

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.

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.  :-(

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.

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.

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.

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.
	* (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.

255181a9ed * dwarfread.c (read_func_scope): Avoid GDB core dumps if
AT_name tag is missing.

	* procfs.c (procfs_stopped_by_watchpoint):  Fix logic when
	FLTWATCH and FLTKWATCH are defined.

	* remote.c (remote_read_bytes):  Advance memaddr for transfers,
	return number of bytes transferred for partial reads.

	* top.c (init_signals):  Reset SIGTRAP to SIG_DFL.

	* target.h, infrun.c (proceed), proceed callers: Pass new code
	TARGET_SIGNAL_DEFAULT instead of -1.  This avoids problems with
	enums being treated as unsigned and is cleaner.
	* infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
	TARGET_SIGNAL_0.
	* infcmd.c (signal_command), infrun.c (signals_info):

	to resume(), proceed(), and target_resume() from int to enum
	target_signal.

	* fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
	* convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
	signal code stuff right with the new signals would be non-trivial).
	* inferior.h (stop_signal): Make it enum target_signal not int.
	* target.c, target.h (target_signal_to_string, target_signal_to_name,
	target_signal_from_name): New functions.

Thomas Lord
199b2450f6 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.

976bb0be03 * Makefile.in (init.c): Generate using the source, not munch. This
cleans up all kinds of hassles (which nm to use in munch, etc).  The
	new formatting conventions (mostly already followed) are that
	the name of the _initialize_* routines must start in column zero,
	and must not be inside #if.
	* munch: Removed.
	* Makefile.in: Remove references to munch.
	* serial.c, remote.c, infptrace.c, maint.c, convex-tdep.c,

	miscellaneous comments and such.
