(got_here): New global variable.
(raise_exception): Fix off-by-2 error so that we _really_ step
to the outermost a() frame.
(get_bsp): New function.
(__builtin_ia64_bsp): Remove.
(a): Print stack and bsp addresses as we recurse.
When resuming execution in outermost a() frame (n==depth),
clear "result" and set "got_here" so we know we landed in
the right place.
(main): Don't accept arguments that cause "depth" to be < 1.
When returning from a(), also check "got_here". If
the check failed, print result, got_here, and nerrors
for diagnostic purposes.

(pkg_minor): Switch to 99.
(pkg_extra): Switch to -alpha.
(CFLAGS): Add -fexceptions if we're compiling with GCC. It's
needed to get the proper unwind tables on platforms
with DWARF unwind info (well, at least on x86 it's needed).

2004/12/02 23:51:00-08:00 hp.com!davidm
(do_backtrace): Also print the symbol offset. Increase nesting-level
tolerance to 64 so we can test programs with deeply nested
call-chains without triggering spurious warnings.

(do_backtrace): Print IP if unw_get_proc_info() fails.

(ia64_make_proc_info): After looking up proc-info, cache it if
caching is enabled.

Adjust for NELEMS to ARRAY_SIZE renaming.

(get_list_addr): Even the "it's missing" version of this routine
must clear *countp to avoid spurious failures.

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.

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.

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.

(tdep_access_reg): Provide a minimally working implementation.
(tdep_access_fpreg): New (unimplemented) function.

(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

2004/12/02 00:40:45-08:00 mostang.com!davidm
Make it possible for dwarf-config.h to define its own version of
dwarf_to_unw_regnum().
2004/11/23 16:59:56-08:00 mostang.com!davidm
(dwarf_to_unw_regnum): Make it a macro so we don't have a
dependency just because of including the file when --enable-debug
is on (and inlining is off).
(dwarf_read_encoded_pointer_inlined): Move from Gpe.c to here
and rename from dwarf_read_encoded_pointer().
(Logical change 1.290)

(unw_tdep_fpreg_t): Make it a union of "double" and two 32-bit words.
(unw_tdep_getcontext): Fix typo.
2004/12/02 00:40:45-08:00 mostang.com!davidm
(_U_TDEP_QP_TRUE): New macro.
(UNW_TDEP_CURSOR_LEN): Increase from 127 to 511 to accommodate
DWARF cursor-size.
(unw_word_t): Change from uint64_t to uint32_t since user-land
PA-Linux is only 32 bits.
(hppa_regnum_t): Add register names UNW_HPPA_EH0, UNW_HPPA_EH1,
UNW_HPPA_EH2, UNW_HPPA_EH3, UNW_HPPA_CFA, and
UNW_HPPA_EH.
(UNW_TDEP_NUM_EH_REGS): New macro.

2004/12/02 00:40:45-08:00 mostang.com!davidm
Include "elf32.h" and "dwarf.h".
(struct unw_addr_space): If we have atomic-ops, define cache_generation
to be of type AO_t.
(struct cursor): Define it primarily in terms of the DWARF cursor.
Add sigcontext_format and sigcontext_addr members.
Add DWARF-location accessors.
(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)
The rationale for this fix is as follows: for the ALIAS directive, RLEN
specifies the number if instructions for which the region behaves like
the aliased code. For example, if RLEN=1 then the code follows the
aliased region for 1 instruction and the valid WHEN values should be 0
and 1. However, with the unpatched code, we would have allowed for -1
and 0, which is wrong.
