Doing some google research, I came across this: http://www.mail-archive.com/gcc@gcc.gnu.org/msg33101.html and http://gcc.gnu.org/ml/gcc-patches/2008-06/msg00025.html and if I disable OPTIMIZE_FOR_SIZE I get this: 00000420 : 420: 55 push %ebp 421: 89 e5 mov %esp,%ebp 423: 83 e4 e0 and $0xffffffe0,%esp Which gives me the right results. Perhaps we need to make FUNCTION_GRAPH depend on !OPTIMIZE_FOR_SIZE, or perhaps if it is only i386 then depend on !(OPTIMIZE_FOR_SIZE && X86_32) :-/ -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
