------- 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
