dump gracefully.
* solib.c (find_solib): Use catch_errors around call to
solib_map_sections. Use warning instead of error if reading of
the shared library name fails.
(solib_map_sections): Change return and argument types to make
it callable from catch_errors.
(symbol_add_stub): Avoid GDB core dump if solib->abfd is NULL.
* irix5-nat.c, osfsolib.c (xfer_link_map_member, solib_map_sections,
symbol_add_stub): Ditto.
* coffread.c (decode_base_type): Treat a long field with size greater
than TARGET_LONG_BIT as long long.
* values.c (value_from_longest): Print code value in error message.
* gdb/gdb_string.h (strdup): Declare only if not defined as a
macro.
Mark glibc development versions are defining strdup as a macro and the
prototype hosees it. Either way, this patch shouldn't cause problems.
* procfs.c: Added replacement macros for LWP stuff. Fixed support
for UnixWare / SVR4.2MP targets and any targets which use
multi-file /proc entries. Fixed support for hardware watchpoints.
* solib.c: SCO needs some of the same code as SunOS. Change
preprocessor conditionals.
* config/i386/i386sco5.mt: New file.
* config/i386/tm-i386sco5.h: New file.
* config/i386/i386sco5.mh (NATDEPFILES): add i386v-nat.o.
* config/i386/nm-i386v42mp.h
(TARGET_HAS_HARDWARE_WATCHPOINTS): define.
Add other macros for hardware assisted watchpoints.
* config/i386/nm-i386sco5.h: Correct attributions.
(TARGET_HAS_HARDWARE_WATCHPOINTS): define.
* config/i386/nm-linux.h (target_remote_watchpoint): Pass
'type' through to i386_insert_watchpoint.
Mon Apr 20 14:12:30 1998 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
* infrun.c (wait_for_inferior): Don't add signalled processes
as new threads.
* procfs.c (wait_fd): Note if LWP has exited.
(procfs_wait): use GETPID to get process ID.
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.
* gdb.base/branches.c: Code with lots of loops and
subroutines. Used to test gdbs ability to single step through PC
changes, especially to test mips-tdep.c:mips_next_pc
(sparc_extract_return_value): New function, required to handle
machines without floating point.
(sparc_store_return_value): Ditto.
* config/sparc/tm-sparc.h (EXTRACT_RETURN_VALUE): Call
sparc_extract_return_value instead of using inline code.
(sparc_extract_return_value): Declare.
(STORE_RETURN_VALUE): Call sparc_store_return_value instead
of using inline code.
(sparc_store_return_value): Declare.
work correctly on little-endian hosts.
(sparc_push_arguments): New function.
(gdb_print_insn_sparc): New function.
(_initialize_sparc_tdep): Make gdb_print_insn_sparc the default
disassembler, so that SPARClite-specific instructions will
be recognized.
* sparcl-tdep.c (readchar): Print debugging information.
(debug_serial_write): New function, a replacement for SERIAL_WRITE
that prints debugging information.
* config/sparc/tm-sparc.h (PUSH_ARGUMENTS): Define.
(sparc_push_arguments): Declare.
* configure.tgt: Switch over to use tm-4320.h. Since I switched to
MIPS EABI the fixes are no longer backward compatible with 4300.
* tm-vr4320.h: Added
* vr4320.mt: Added
zap one group of persistent gdb testomat failures.
Mon Apr 13 22:32:51 1998 Frank Ch. Eigler <fche@cygnus.com>
* gdb.c++/virtfunc.cc: Make extern "C" printf declaration pass
more rigorous EGCS C++ error checking.
* utils.c: (warning) added call to warning_hook
* source.c: (find_source_lines) modified to call warning in case
of source vs. executable time stamp mismatch. Simplified object
file check. Initialized mtime to 0.
* defs.h: added warning_hook prototype
* top.c: added warning_hook prototype.
* gdbtk.c: (perror_with_name_wrapper) new function to call
perror_with_name safely.
(gdb_loadfile) added source vs. executable time stamp check.
(gdbtk_warning) new function to pass a warning message to the gui.
(gdbtk_ignorable_warning) new function to pass a warning
to the gui. Used only for the src. vs. exec check.
(gdbtk_init) added warning_hook
added include <sys/stat.h>
timer interval a little.
(gdbtk_stop_timer): Include on all platforms.
(gdbtk_wait): No more signals! Use a timer on all platforms to keep the
GUI alive.
(gdbtk_init): Remove FIOASYNC and all x_fd references. Now using timers
on all platforms.
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.
