* tests/ia64-test-setjmp.c (doit): New forward declaration.
(doit_pointer): New function pointer variable initialized to DOIT.
(doit): Self-call made by an unoptimizable volatile indirect call.
* tests/test-ptrace.c (target_pid_kill): New function.
(target_pid, main): TARGET_PID made static, for target_pid_kill ().
(main): Register target_pid_kill () for atexit(3).

* tests/Gtest-dyn1.c, tests/test-async-sig.c, tests/test-ptrace.c:
Fixed lockups on broken libunwind (as ppc64 is).
2007-03-07 Jan Kratochvil <jan.kratochvil@redhat.com>
* tests/test-async-sig.c (do_backtrace): Limit maximum backtrace depth
to 100 iterations; it workarounds FC6 DWARF-broken glibc.
2006-12-10 Jan Kratochvil <jan.kratochvil@redhat.com>
* tests/test-ptrace.c (main): Check for too many unexpected child
signals, such as the common `SIGSEGV'.
This is so that the source file gets distributed and _ucontext_i.h is
generated properly on the target machine.

When libunwind is linked with a C++ program that throws exceptions,
the exception that's thrown is passed in %rax. However, libc's
setcontext clears %rax, causing problems.
This patch implements a setcontext that doesn't clobber rax.
TBD: Add dwarf CFI annotations

include/dwarf.h: Declare dwarf_reg_state_pool and dwarf_cie_info_pool.
include/dwarf_i.h: Include libunwind_i.h instead of tdep.h.
Make dwarf_to_unw_regnum() a macro so it doesn't get compiled
into an object file merely because it include dwarf_i.h (important
when optimization is turned off).
(dwarf_read_encoded_pointer_inlined): New function.
include/tdep-x86/libunwind_i.h: Add include of "mempool.h".
include/tdep-x86_64/libunwind_i.h: Add include of "mempool.h".
Yes, it casts to signed, but then converts right back to
unsigned via the return type. Fixed thus.

CFA should be incremented by 16 in the hope that the previous frame
may have valid unwind info.
Also increase the default frame pointer recognition heuristic from 4k
to 16k.

Now that dwarf_find_save_locs() not just finds the save-locations but
also updates the cursor-state, document this fact (the function really
is misnamed now).
