ec8ceca3f3 * 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).

4ace50a510 Remove now obsolete signame.c and signame.h; functionality is handled by
libiberty/strsignal.c.  Widespread changes to use libiberty/strerror.c
functions for errno manipulations and libiberty/strsignal.c for signo
(signals) manipulations.

stopped during attach, thus stopping it again.

5c1c5e6745 Fix bug in values.c unpacking signed characters on hosts where the default
character type is unsigned.  Add some cases to the tables in procfs.c
for constants defined in newer SVR4 systems and reorder the tests for
ioctl support of resetting the inherit-on-fork flag to favor the latest
method using PIOCRESET.

cc221e76d6 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.

6b80138803 Changes in procfs.c to fix bug with inferior's siginfo struct getting
needlessly stomped.  Changes in elfread.c and solib.c to fix DWARF
processing, broken by other recent changes.

fad3fc945a * procfs.c (open_proc_file): Disable inherit-on-fork flag so that

* All GDB files that #include defs.h: Removed stdio.h.
	(defs.h): #include stdio.h.

This has been tested by building GDBs for all targets hosted on Sun4.
None of the build problems were related to stdio.h inclusion.  (n.b.
many configurations don't build for other reasons.)

a39ad5ce42 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".

f8b76e70b7 Numerous small changes and a complete reorganization of solib.c, to support
SVR4 shared libraries in a manner very close to the original SunOS support.

This is required to supply some typedefs used in files included via
param.h.
