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). //Tapani -- tapani at chalmers dot se changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |tapani at chalmers dot se http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29473
