Can someone enlighten me ?

Can someone enlighten me ? The new architecture still supports 32-bit opcodes, even when running the application in 64-bit mode, so the opcodes will still be translated into valid code. This code will most likely, however, not run. I think there are at least these obstacles: - Calling conventions will change - Stack alignment will change - Stack layout will change (because of larger pointers) - IIRC Windows will drop FPU and MMX support on 64-bit platforms (replaced SSE) Even if the code were modified to deal with these, it would no longer be optimal; it would probably even be slower than compiler-generated code. -- The Fastcode Project: http://www.fastcodeproject.org/ Back to top Matthias Pfohl Guest Posted: Sat Jan 28, 2006 6:13 pm    Post subject: Re: Assembly routines and 64 bit Hello Avatar, Thanks for the info.
