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.

* cpux.h,decodex.c,decodex.h,readx.c,semx.c: Regenerate.
Main change is to remove ordinal from format names.
|
|
|
|
* gdbtk.c (gdb_listfiles): Allocate space for 'files' dynamically.
Harumph, my change got lost in the foundry->devo merge.

before any other symbols in the same section.
Required by Visual C++ linker, and specified in PE documentation.

* 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.

(compute_mpgloc): New function.
(eval_expr): New arg `cpu'. All callers updated.
(non_vu_insn_seen_p): New static global.
(RELAX_{MPG,DIRECT,VU,ENCODE,GROWTH,DONE_}): New macros.
(struct dvp_fixup): New member `cpu'.
(assemble_one_insn): New args init_fixup_count, fixup_offset.
All callers updated.
(md_assemble): Set non_vu_insn_seen_p as appropriate.
(assemble_vif): Set `cpu' field of fixup.
Clean up calls to frag_var. Recorded mpgloc is now in bytes.
(assemble_vu_insn): Delete, contents moved into ...
(assemble_vu): ... here. Don't record fixups until after parsing
both upper and lower insns. If branch insn inside mpg, properly
compute target address.
(dvp_frob_label): Create copies of vu labels inside mpg's.
(dvp_relax_frag): Clean up.
(md_convert_frag): Ditto.
(md_apply_fix3): Signal error if mpg embedded vu code has branch
to undefined label (not currently supported).
(eval_expr): New arg `cpu'. All callers updated.
(insert_operand_final): Convert mpgloc from bytes to dwords.
(s_endmpg): Use compute_mpgloc to update $.mpgloc.
(s_state): If switching to vu state, initialize $.mpgloc.

registers for a VU. Behavior not as mandated.

work!
[ChangeLog.sky]
* sky-vu.h (vu_device): Represent "macro instruction just stuffed
into fetch buffer" condition with new "m" bit. Rename old "m" to
"l".
* sky-libvpe.c (indebug): Save snapshot of environment value;
workaround for suspected memory corruption.
(fetch_inst): Respect new "m" macro-instruction flag for reporting
successful fetch to caller.
(exec_inst): Disassemble instruction here instead of fetch time.
Renamed old "m" -> "l" flag in VU state to track interlock
release.
(vpecallms_cycle): Call exec_inst only if fetch_inst did some
work.
* sky-vu.c (vu_attach, vu[01]_device): Revamped initialization to
ensure complete clear of tail part of struct at attach time.
(vu0_busy): Fix thinko.
(vu0_macro_issue): Adapt to new "l" flag.
(vu0_micro_interlock_released): Ditto.
(write_vu_special_reg): Ditto.
(read_vu_special_reg): Compute VBS0/VBS1 bits more explicitly.
The other VU status bits are not yet computed.

* interp.c (decode_coproc): Do not apply superfluous E (end) flag
to upper code of generated VU instruction.
