I've a question about the test in
gcc-4.0-20050102/gcc/testsuite/gcc.target/i386/defines-2.c
---------------------------------------------------
/* { dg-do compile } */
/* { dg-options "-march=athlon64 -mno-mmx" } */
#if defined(__MMX__) || defined(__3dNOW__) || defined(__3dNOW_A__)
#error
#endif
---------------------------------------------------
Why checking for defined(__3dNOW__) with -mno-mmx and -march=athlon64 ?

But how can I implement unimaginable chaos in my compiler?
