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.

Mine didn't shown up. In any case, I have 18580+ execution test failures.

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).
