Update support for x86 Solaris 2.
* config/i386/tm-i386sol2.h, nm-i386sol2.h: New configuration
files for x86 Solaris 2.
* config/i386/i386sol2.mt, i386sol2.mh: Use them.
* config/sparc/tm-sun4sol2.h (PROCFS_GET_CARRY): New macro, extract
carry flag from a given regset.
(IS_STATIC_TRANSFORM_NAME): New macro, check if a symbol name
is a SunPro transformed name.
* i386-tdep.c (sunpro_static_transform_name): New function to
extract the source name from a SunPro transformed name.
* inferior.h (procfs_first_available, procfs_get_pid_fd):
Add prototypes.
* infrun.c (wait_for_inferior): Handle breakpoint hit in
signal handler without intervening stop in sigtramp.
* procfs.c (procfs_lwp_creation_handler): Use PROCFS_GET_CARRY
instead of direct access to the status register.
(procfs_get_pid_fd): New function, returns procfs fd for a given pid.
* sol-thread.c (ps_lgetLDT): New function, returns LDT for a given
lwpid.
(sol_find_new_threads): Handle failed libthread_db initialization
gracefully.
* stabsread.c (define_symbol): Use IS_STATIC_TRANSFORM_NAME
to check for a SunPro transformed symbol name.
* gdb.base/help.exp: Clean up `help set args' and `help show args'
tests.
* gdb.base/interrupt.exp: Add "i*86-*-solaris2*" xfail for calling
function when asleep.
* gdb.base/signals.exp: Add "i*86-*-solaris2*" xfails. Add comment
for i*86 Linux and SVR4 signal handling problems.
Remove linux xfail for `next to handler in signals_tests_1', fixed
by recent infrun.c change.
Limit backtrace to 10 frames to avoid timeout problems with infinite
stack backtraces.
Adjust expect pattern in `handle all print' test to match Apr 28 1997
target.[ch] change.
* mips-tdep.c (unpack_mips16): Fixed instruction decoding, lots of
bit pattern interpretations. mips_fetch_instruction does not work
for 16 bit instructions. Some confusion remains about sign
extension in backward branches.
(mips32_relative_offset): Sign extension
(mips32_next_pc): Major debugging, bit pattern interpretation
(print_unpack): debugging printf
(fetch_mips_16): new funtion, key on PC low bit, not symbol table
(mips16_next_16): Initial major debugging of this function. Lots
of bit pattern mistakes.
(mips_next_pc): key on low bit of PC, not symbol table.
* symfile.c(generic_load) : Added a download verification which
reads back the loade code. Download chunk size is now a defined
macro. Fixed a bug in which downloading slips into loading one
byte at a time. Lower level functions in monitor.c can load long
sequences of bytes and make use of these fixups. Referencing
bfd-start_address directly was incorrectly getting zero for start.
section in an ELF file, override a symbol's ECOFF section with its
ELF section. Also, fix stabs continuation where a stabs string
continues for more than one continuation.
Thu Apr 2 12:47:41 1998 Frank Ch. Eigler <fche@cygnus.com>
* sol-thread.c (sol_thread_store_registers): Save & restore new
value of single updated register to prevent accidental clobbering.
* ns32k-tdep.c (flip_bytes, ns32k_localcount,
ns32k_get_enter_addr, sign_extend): Restore functions mysteriously
deleted.
* ns32knbsd-nat.c: New (?) file to support fetching and storing
registers on NetBSD hosts.
* nbsd.mh (NATDEPFILES): put ns32knbsd-nat.o instead of
ns32k-nat.o
* ns32km3-nat.c (reg_offset): Get order of floating point
registers correct. Add extra 32382 register offsets.
(REG_ADDRESS): define to point at correct part of thread
state. Use calls to "warning" instead of "message".
* tm-nbsd.h, tm-ns32km3.h (REGISTER_NAMES, NUM_REGS,
REGISTER_BYTES, REGISTER_BYTE): redefine allowing for 32382
fpu registers.
* rdi-share/Makefile.am, rdi-share/aclocal.m4,
rdi-share/configure: New files.
* rdi-share/configure.in: Rewritten to be an autoconf input file.
* rdi-share/Makefile.in, rdi-share/configure: Generated by
automake/autoconf.
* rdi-share/dbg_hif.h, etherdrv.c, hostchan.c: Use autoconf tests
to check environment.
automake/autoconfiscate rdi-share. We don't use the checks that autoconf
provides too much for now, but it'll be easier to use them if any problems
crop up in the future. (rdi-share/ is foreign code and it probably isn't
worth spending any more time than necessary messing with it.)
* gdbtk.c: (gdb_trace_status) new function.
(gdbtk_init) added command "gdb_is_tracing".
(tracepoint_notify) added passcount information.
* tracepoint.c (trace_status_command): Recognize a boolean return
value from the stub to indicate whether trace experiment is
running. Export this value as a global state variable
(trace_running_p) for use by the GUI. (from Michael Snyder)
(trace_pass_command) added call to modify_tracepoint_hook.
* tracepoint.h export trace_running_p
* gdbtk.c (gdbtk_fputs): Insert fencepost.
(gdb_loc): Correct pc calculation.
(gdb_immediate_command): Return if a load is in progress.
(gdb_cmd): Return if a load is in progress.
(target_stop_wrapper): New function.
(gdb_stop): Call target_stop_wrapper.
(x_event): Add fencepost and optimize load cancel check.
(gdbtk_start_timer): Set up structs only once.
(gdbtk_stop_timer): Just use preset structs to set timer parameters.
(gdb_loadfile): If file cannot be loaded, return error message.
(gdb_loadfile): Add space before tab so that lines without
a '-' can later be changed to have one.
* config/d10v/d10v.mt config/d30v/d30v.mt config/m32r/m32r.mt
config/mn10200/mn10200.mt config/mn10300/mn10300.mt : Remove -lm
from SIM. This prevents dependency checking of -lm (under NT
native builds). (It is automatically added by configure if it
exists.)
* doc/configure mswin/configure nlm/configure
testsuite/gdb.base/configure testsuite/gdb.c++/configure
testsuite/gdb.chill/configure testsuite/gdb.disasm/configure
testsuite/gdb.stabs/configure testsuite/gdb.threads/configure:
Regenerate with autoconf 2.12.1 to fix shell issues for NT native
builds.
* breakpoint.c (breakpoint_re_set_one): Treat bp_shlib_events
like bp_breakpoints.
* solib.c (solib_create_inferior_hook): Relocate section addresses
if the alleged start address doesn't agree with the PC.
merged changes from Foundry (list follows by file/author):
- Tom Tromey <tromey@cygnus.com>
* Makefile.in (gdbres.o): New target.
(WINDRES): New define.
* configure: Rebuilt.
* configure.in (WINDRES): Define.
(CONFIG_OBS): Include gdbres.o on Windows.
* gdbtool.ico: New file.
* gdb.rc: New file.
* ser-unix.c
- Keith Seitz <keiths@onions.cygnus.com>
(wait_for): Don't reset the timeout_remaining for CYGWIN32,
since we now effectively poll the serial port.
Don't reset the current_timeout, either, since this member is used
by hardwire_readchar to track the timeout and call the ui_loop_hook.
(hardwire_readchar): Poll the serial port for Cygwin32. We timeout every
second, update the UI, and loop around doing this until we have hit the real
timeout or we get data or an error. This will allow the UI to stay active
while gdb is "blocked" talking to the target.
- Martin M. Hunt <hunt@cygnus.com>
(wait_for): Do reset current_timeout
because it is only used to keep track of what the
current timeout for the scb is.

for GUI.
(pc_changed_hook): Add prototype.

"set remotelogbase".
* findvar.c
- Martin M. Hunt <hunt@cygnus.com>
(write_register_gen): Add call to
pc_changed_hook if the PC is being changed.
* defs.h
- Martin M. Hunt <hunt@cygnus.com>
(pc_changed_hook): Define.
* command.c
- Martin M. Hunt <hunt@cygnus.com>
(do_setshow_command): If no arguments are supplied,
don't dump core, instead print out an error message.
* breakpoint.c
- Martin M. Hunt <hunt@cygnus.com>
Make set_raw_breakpoint, set_breakpoint_count,
and breakpoint_count non-static so they are accessible from
gdbtk.c.
(enable_breakpoint): Enable breakpoint
with same disposition instead of changing all breakpoints
to donttouch.
* annotate.h
- Keith Seitz <keiths@onions.cygnus.com>
Add declarations for annotation hooks.
* annotate.c
- Keith Seitz <keiths@onions.cygnus.com>
Add hooks: annotate_starting_hook, annotate_stopped_hook,
annotate_signalled_hook, annotate_exited_hook.
(annotate_starting): If hook exists, call it instead.
(annotate_stopped): If hook exists, call it instead.
(annotate_exited): If hook exists, call it instead.
(annotate_signalled): If hook exists, call it instead.

Check that REGISTER_{RAW,VIRTUAL}_SIZE are consistent when the target
specifies that no conversion is needed when moving from one to the
other.
