Description Richard Biener 2008-08-08 14:54:59 UTC 
I see

FAIL: gcc.dg/tree-prof/bb-reorg.c compilation,  -fprofile-use -D_PROFILE_USE
UNRESOLVED: gcc.dg/tree-prof/bb-reorg.c execution,    -fprofile-use -D_PROFILE_U

FAIL: gcc.dg/tree-prof/pr34999.c compilation,  -fprofile-use -D_PROFILE_USE
UNRESOLVED: gcc.dg/tree-prof/pr34999.c execution,    -fprofile-use -D_PROFILE_US
E

which is because

pr34999.s: Assembler messages:
pr34999.s:114: Error: .cfi_endproc without corresponding .cfi_startproc
pr34999.s:124: Error: open CFI at the end of file; missing .cfi_endproc directive

as both testcases use -freorder-blocks-and-partition (?)

> as --version
GNU assembler 2.16.91.0.5 20051219 (SUSE Linux)

and

GNU assembler (GNU Binutils; openSUSE 11.0) 2.18.50.20080409-11.1
Comment 1 Andrew Pinski 2008-08-10 19:54:08 UTC 
It works with "2.17.50 20070213" on powerpc64-linux-gnu.
Comment 2 Jakub Jelinek 2008-08-12 09:46:56 UTC 
-freorder-blocks-and-partition never really worked with EH, whether you get
assembler errors as with the .cfi_* directives or whether it just silently
generates bogus unwind info is unimportant.  GCC isn't able to track the unwind
info for two separate sections ATM.
