Description H.J. Lu 2010-07-07 00:36:36 UTC 
On Linux/ia32, revision 161877 gave:

FAIL: /export/gnu/import/svn/gcc-test/bld/i686-pc-linux-gnu/libjava/testsuite/TestEarlyGC.exe execution - /export/gnu/import/svn/gcc-test/bld/i686-pc-linux-gnu/libjava/testsuite/TestEarlyGC.exe
....

revision 161871 is OK. It may be caused by revision 161876:

Comment 1 H.J. Lu 2010-07-07 00:41:14 UTC 
There are so many failures that they won't show up at

http://gcc.gnu.org/ml/gcc-testresults/2010-07/

nor

http://gcc.gnu.org/ml/gcc-regression/2010-07/

since the messages are too big.
Comment 2 Andrew Pinski 2010-07-07 00:42:20 UTC 
Actually it did:

Comment 3 H.J. Lu 2010-07-07 00:44:47 UTC 
Mine didn't shown up. In any case, I have 18580+ execution test failures.
Comment 4 H.J. Lu 2010-07-07 00:50:03 UTC 
I also have MANY execution test failures on Linux/x86-64.
Comment 5 Jakub Jelinek 2010-07-07 07:17:22 UTC 
Yeah, the amount of regressions is huge, both on x86_64-linux and i686-linux.

The difference is in i386 now overriding config/elfos.h definition:
/* Write the extra assembler code needed to declare a function properly.
   Some svr4 assemblers need to also have something extra said about the
   function's return value.  We allow for that here.  */

#ifndef ASM_DECLARE_FUNCTION_NAME
#define ASM_DECLARE_FUNCTION_NAME(FILE, NAME, DECL)             \
  do                                                            \
    {                                                           \   
      ASM_OUTPUT_TYPE_DIRECTIVE (FILE, NAME, "function");       \
      ASM_DECLARE_RESULT (FILE, DECL_RESULT (DECL));            \
      ASM_OUTPUT_LABEL (FILE, NAME);                            \
    }                                                           \
  while (0)
#endif

(and config/darwin.h, config/netbsd-aout.h and config/openbsd.h too).
