------- Comment #8 from tapani at chalmers dot se 2007-08-08 17:23 -------
The "rep ret" bug is not athlon64 specific.
I have a similar bug where gcc-4.2.1 generates several "rep ret" instructions,
without me using -march=athlon64. In my case, it seems to be triggered by a
combination of "-masm=intel", "-O" and "-fomit-frame-pointer".
I am using a vanilla gcc 4.2.1, on a plain GNU/Linux IA32 (Pentium 4 CPU, so
really nothing to do with athlon64 or x86_64).
