(ia64_make_proc_info): After looking up proc-info, cache it if
caching is enabled.
2005/02/20 21:42:55-08:00 mostang.com!davidm
Adjust for NELEMS to ARRAY_SIZE renaming.
(Logical change 1.290)
2004/12/02 18:37:47-08:00 hp.com!davidm
(get_list_addr): Even the "it's missing" version of this routine
must clear *countp to avoid spurious failures.

Auto merged
2004/10/21 16:06:28+02:00 homeip.net!davidm
(get_list_addr): Don't fail with -UNW_ENOINFO just because something
in /proc/maps isn't mappable.
(Logical change 1.290)
2004/11/30 22:44:47-08:00 mostang.com!davidm
(my_rt_sigreturn): New function.
(x86_64_local_resume): Use my_rt_sigreturn(). The normal sigreturn()
does nothing (returns with an error).
2004/11/23 18:01:09-08:00 mostang.com!davidm
(x86_64_local_resume): Provide a minimal implementation (a la x86).
(establish_machine_state): Fix off-by-one error.
(Logical change 1.290)
local case since it's trivial to do so and saves us time if
later on we need to build a script for that procedure.
2005/02/23 14:40:44-08:00 mostang.com!davidm
Adjust for sigset_t to intrmask_t renaming.
2004/10/25 05:21:51-07:00 hp.com!davidm
(unw_search_ia64_unwind_table): Clarify comment and add a Debug() statement
for the case where we find a bad unwind-header version.
(Logical change 1.290)
(access_reg): Adjust & enable sanity-check.
(acces_fpreg): Provide minimal implementation.
2004/12/02 00:40:45-08:00 mostang.com!davidm
(uc_addr): Implement it so it starts to be useful.
(_Uhppa_uc_addr): Rename from _Ux86_uc_addr.
(get_static_proc_name): New function.
(hppa_local_addr_space_init): Rename from x86_local_addr_space_init().
Use dwarf_find_proc_info, hppa_local_resume, and
get_static_proc_name callbacks.
(Logical change 1.290)
eh_valid_mask instead. When reading and the corresponding
eh_valid_mask bit is set, read from eh_args[] instead.
2004/11/17 02:43:39-08:00 mostang.com!davidm
(tdep_access_reg): Treat UNW_X86_64_RSP exactly like UNW_X86_64_CFA.
(Logical change 1.290)
and UNW_HPPA_EH{0,1,2,3} correctly.
(tdep_access_fpreg): Implement.
2004/12/02 00:40:45-08:00 mostang.com!davidm
(tdep_access_reg): Provide a minimally working implementation.
(tdep_access_fpreg): New (unimplemented) function.
(Logical change 1.290)
(put_script_cache): Fix typo in argument name.
2005/04/07 12:19:38-07:00 hp.com!davidm
(ia64_get_cache_proc_info): Move it to near the end of the file.
(script_init): Also call ia64_fetch_proc_info() if the script was
found in the cache but it's empty (count == 0 and NULL
unwind_info pointer). Also invoke build_script() if
script has no instructions yet (count==0). Add assertion
to ensure that build_script() never returns an empty
script.
(ia64_cache_proc_info): New function to cache the proc_info only.
2005/02/23 14:40:44-08:00 mostang.com!davidm
Adjust for sigset_t to intrmask_t renaming.
2005/02/23 13:10:05-08:00 mostang.com!davidm
Adjust for "ia64_rse" to "rse" prefix change.
(Logical change 1.290)
2004/10/19 23:15:02-07:00 mostang.com!davidm
(update_frame_state): Take additional argument "prev_cfa".
When we detect a NULL-frame, debug-print the IP and the CFA
so we know where things went wrong.
(dwarf_step): Get "prev_cfa" before we call dwarf_find_save_locs(),
since update_frame_state() doesn't actually update
the CFA.
(Logical change 1.290)
(pick): Likewise.
(dwarf_eval_expr): Fix "while" conditional so we see all operators.
Fix DW_OP_litN typo: "opcode = DW_OP_lit0" to
"opcode - DW_OP_lit0".
Add lots of Debug() statements so we can see what's going
on. Debug level 15 will show just entry/return values.
Debug level 16 shows all operators.
(Logical change 1.290)
_U_dyn_info_list_addr as weak and fail if the symbol remained
undefined.
(get_static_proc_name): Likewise for _Uelf64_get_proc_name().
(Logical change 1.282)
successfully. This avoids a failure in ia64-test-setjmp which
was due to the fact that sigprocmask() caused a segfault (due to
overflowing the stack) and at that point we had a partially updated
jmp_buf.
(Logical change 1.272)
For ia64, if the longjmp is crossing a signal-frame, install
the new signal mask by updating the sc_mask member in the
oldest signal-frame.
(Logical change 1.259)
(rbs_cover_and_flush): Take additional arguments "dirty_partition",
"dirty_rnat", and "bspstore". When it is necessary to copy
backing-store words, copy them to "dirty_partition" instead of
the target rbs, which may be full already.
(Logical change 1.259)
from lib_LTLIBRARIES_cdep to here.
(libunwind_la_SOURCES_x86_64_common): Mention x86_64/ucontext_i.h so
it gets included in the tar-ball, too.
(lib_LTLIBRARIES): List $(lib_LTLIBRARIES_cdep_setjmp) after the
other libraries.
(Logical change 1.254)
printing them. Avoids compiler-warning for 64-bit targets.
(apply_reg_state): Handle the special case where the stack-pointer
plays the role of the CFA and the stack-pointer hasn't
been saved. This is based on a patch by Max Asbock.
(Logical change 1.253)
In theory, this may not be needed. In practice, I find that
Red Hat Enterprise Linux AS release 3, the _start() routine has
no unwind-info, but we need to be able to unwind into this
routine to find the end-of-frame-chain marker (RBP == 0).
(Logical change 1.253)
Drop DWARF-parsing debug prints from level 16 to 15.
(struct table_entry): Change member types from unw_word_t to int32_t. The members
need to be of a signed type and forcing them to 32 bits makes the type
work for both 32-bit and 64-bit executables (up to 4GB of text-size).
(callback): Only allow search tables which have 32-bit members.
Fix initialization of di->u.rti.table_len to express table-length as a count
of unw_word_t, as it's defined to be (we get lucky here: even with 32-bit
members, each table-entry contains two members so we're guaranteed that the
table has a size that is an integer-multiple of unw_word_t even on 64-bit
platforms).
(lookup): Change type of "rel_ip" from unw_word_t to int32_t. Simplify the
code a bit.
(remote_read): Delete.
(remote_lookup): Use dwarf_reads32() instead of remote_read() to read out table
members. Simplify code a bit.
(Logical change 1.248)
