--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> 2010-12-27 20:19:34 UTC ---
Your testcase is invalid as you don't change back the section before the end of
the inline-asm.
Try:
static void asm_wrapper()
{
    asm volatile (
        ".text\n"
        ".globl " "ctiTrampoline" "\n"
        ".hidden " "ctiTrampoline" "\n"
        "ctiTrampoline" ":" "\n"
        "pushl %ebp" "\n"
        "movl %esp, %ebp" "\n"
        "pushl %esi" "\n"
        "pushl %edi" "\n"
        "pushl %ebx" "\n"
        "subl $0x3c, %esp" "\n"
        "movl $512, %esi" "\n"
        "movl 0x58(%esp), %edi" "\n"
        "call *0x50(%esp)" "\n"
        "addl $0x3c, %esp" "\n"
        "popl %ebx" "\n"
        "popl %edi" "\n"
        "popl %esi" "\n"
        "popl %ebp" "\n"
        "ret" "\n"
        ".previous" "\n"
        );
}
