ia64: Fix and clarify access to UNW_IA64_PR.
Access to the rotating portion of UNW_IA64_PR was busted. Also, libunwind
incorrectly attempted to rotate this portion when it should work like the
"move predicates" instructions and access them in unrotated form.

(save_pr): Declare
(check_pr): New function.
(all_funcs): Mention save_pr/check_pr.
(random_word): New function.
(check_pr): Likewise.
(check_rotate_regs): Call check_pr().
(run_check): Use random_word() instead of random() to get a word full of
pseudo-random bits.
(Logical change 1.292)
to create NTHREADS threads. With NTHREADS==128 and the stack-size
rlimit set to "unlimited", the test is otherwise likely to fail because
on ia64 it will default to using 32MB of stack per thread.
(Logical change 1.291)
(consume_some_stack_space): New function.
(main): Call consume_some_stack_space() before establishing the
rlimit. Otherwise, stack-expansion may bump into
the address-space rlimit.
(Logical change 1.290)
Abstract ia64-specific code into bsp_match() routine.
Support any platform with at least 2 EH argument registers.

Rename: src/longjmp.c -> src/setjmp/longjmp.c

(struct callback_data): New structure.
(linear_search): New function.
(callback): Convert to getting auxiliary info passed via a pointer to
a callback_data structure, rather than an unw_dyn_info_t
structure.
Keep track of the maximum load address in max_load_addr.
If an object doesn't have a binary search-table, fall back
on a linear search.
(dwarf_find_proc_info): Fill in callback-data structure before calling
dl_iterate_phdr(). Upon returning, check whether
cb_data.single_fde is set and, if so, return directly, without
searching the DWARF unwind-table.
(dwarf_search_unwind_table): Adjust for renaming of
dwarf_parse_fde() to dwarf_extract_proc_info_from_fde().
If IP doesn't fall into the IP-range of the FDE-entry found
by the search, return UNW_ENOINFO.
(Logical change 1.290)

Include "tdep.h" on ia64 (we need the cursor).
(bsp_match): Fix it so it compiles again.
(resume_restore_sigmask): Likewise.

(_UPT_access_reg): If the register is out of range, set errno
to EINVAL.
When encountering an error while accessing a register,
print the corresponding error string.

a signal-trampoline, assume that it's a PLT stub.
If non-DWARF stepping fails to change IP and CFA, declare
it a bad frame.
2004/11/23 16:59:56-08:00 mostang.com!davidm
(unw_step): Also print IP as part of the function-trace.
2004/11/23 16:17:37-08:00 mostang.com!davidm
(unw_step): When dwarf_step() fails on a signal-frame, fill in all
the known locations because dwarf_step() fails on older
kernels which don't export the kernel vDSO even though every-
thing else may be providing proper DWARF unwind-info.

Add Debug statement for return-value.
(Logical change 1.290)
2004/11/23 12:49:54-08:00 mostang.com!davidm
(unw_step): If dwarf_step() fails on a signal-frame, fill in the
save-locations for everything that gets saved in the
sigcontext structure.
