--- Comment #17 from sje at cup dot hp dot com 2010-09-23 16:27 --- It looks like GCC on IA64 HP-UX has a problem when a routine in .text.unlikely calls a function in .text. If I define UNLIKELY_EXECUTED_TEXT_SECTION_NAME and HOT_TEXT_SECTION_NAME to just be '.text' then I can bootstrap with partial inlining enabled. I think the bug that is causing the abort is probably in the GNU assembler or the HP linker or some combination of the two. There is still a GCC bug here because the partial inlining change shouldn't have triggered the use of .text.unlikely. Particularly since it appears that it is the caller of the partially inlined function that is getting put into .text.unlikely, not the 'remainder' of the partially inlined function. On IA64 Linux, we do not appear to be using .text.unlikely, and that is probably why I see this bug on HP-UX but not Linux. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44716

I have a slightly smaller test case for this, but it still needs to bootstrap
to fail. If I bootstrap just the C part of the compiler I get a successful
build (with partial inlining enabled) but when I use that compiler to compile
this test case (with -O2) I get a segfault in the compiler:
char *s4;
test2_sub (int i, ...)
{
__builtin_va_list ap;
__builtin___vsprintf_chk (s4, 0, __builtin_object_size (s4, 0), "%s %d", ap);
}
If I modify the gimple_rewrite_call_expr call in builtins.c and replace the
call to gimple_call_num_args with a new function that I don't inline (or that I
inline completely) the segfault goes away.
Looking at some of the dump files, builtins.c.041t.fnsplit shows
gimple_call_num_args getting split but I don't see any indication of inlining
in builtins.c.015/025/043. fnsplit creates gimple_call_num_args.part.22 and
changes gimple_call_num_args to call that routine the dump doesn't show
imple_rewrite_call_expr calling part.22 but later dumps do show this. I will
attach builtins.c.041t.fnsplit.
Any help on this bug would be appreciated, IA64 HP-UX has not bootstrapped with
ToT sources in some time now.

--- Comment #3 from sje at cup dot hp dot com 2010-07-07 15:30 --- I haven't been able to come up with a test case other then bootstrapping. If I build a non-bootstrap compiler and run the testsuite I don't get any unexpected failures due to this problem. It is only when, during bootstrap, I run the cc1plus executable that was built by the stage1 cc1 that I get a failure. At that point trying to compile any C++ program with cc1plus results in cc1plus aborting. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44716
