[Bug target/23909] Incorrect code generated for SSE2 based xor routine when compiled with -O2 -fomit-frame-pointer

      __asm__ __volatile__(
                           "add     %1,       %0\n"
                           "movaps   0(%0),   %%xmm0\n"
                           "movaps  16(%0),   %%xmm1\n"
                           : : "r" (bptr[0]), "r" (offset));

This asm is wrong, it does not tell the compiler that it modifies memory or
even xmmm? registers.

Really you should be using SSE instrincs functions.
