gas generating bad code for i386

[Tom Riddle <ftr at oracom dot com>]

I think a bug was introduced somewhere between releases
2.9.1.0.23 and 2.9.5.0.22 that causes the following code:

        __asm__ __volatile__ (...
                "je 4\n\t"
                 ...);

To produce:
0x80483b6 <main+22>:    je     0x4

Whereas 2.9.1.0.23 (correctly) gives:
0x80483b6 <main+22>:    je     0x80483bc <main+28>

Version:
GNU assembler version 2.9.5 (i386-redhat-linux) using BFD version
2.9.5.0.22

Reproduce the problem with the following code:

int main(int argc, char **argv)
{
        int count;
        void *p1;
        void *p2;
        int __res;

        __asm__ __volatile__ ("cld\n\t"
                "repe\n\t"
                "cmpsl\n\t"
                "je 4\n\t"
                "sbbl %%eax,%%eax\n\t"
                "orb $1,%%al\n"
                :"=a" (__res):"0" (0),"S" (p1),"D" (p2),"c" (count)
                :"si","di","cx");
        return __res;
}
