[gmx-users] binutils

[Erik Lindahl]

Hi,

Please write this code into a file "test.s":

----------
.intel_syntax noprefix
checkasm:
         lock cmpxchg [[esi]], ebx
         emms
         ret
-------------

And try to assemble it with

qcc -c test.s

It _might_ be that version 2.12.1 was a bit too conservative. The  
crucial part is the "lock" prefix to cmpxchg.

Cheers,

Erik
