(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)
(main): Do some silly FP computations. On x86-64, this ensures
that the signal handler invocations will always be called
with the FPU-state saved as well. Without this, the first
signal was invoked without FPU-state, the second with, causing
a spurious failure.

(get_bsp): New function.
(handler): Clean up & check for error returns.
(main): Also fail if we didn't get SIGUSR2.
(Logical change 1.290)
for SuSE LES 9) so use 128KB instead.
(do_backtrace): Also print backtrace obtained via backtrace().
(foo): Remove backtrace() call---now done in do_backtrace().
(Logical change 1.290)

(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.

(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.
2004/11/23 18:01:09-08:00 mostang.com!davidm
(do_backtrace): Fix "start_ip might be used uninitialized" warning.
(Logical change 1.290)
Include <errno.h>.
Include <ia64intrin.h> if we have it.
(get_bsp): New function.
(doit): Use get_bsp() instead of __builtin_ia64_bsp().
(main): Replace %m with %s/strerror(errno).
(Logical change 1.277)
(num_errors): Likewise.
(do_backtrace): Only print info if verbose is set.
(foo): Likewise.
(sighandler): Likewise.
(main): Likewise.
(bar): New function which is attempting to trigger a bug reported by
Anthony Brewer which is caused by GAS apparently generating bad
offsets for the psprel directive.
(f): New function.
