Lemme put it this way. I am willing to write the patch to change GCC
if and only if I do not have to write configure macros. And configure
macros must be written unless we can prove that "cs/je", "rep/stosl",
etc. are acceptable by all the assemblers that people care about,
since time immemorial.
So you get three choices:
1) Make GAS accept cs;je and do the right thing.
2) Prove that cs/je, rep/stosl, etc are acceptable to all i386
assemblers since time immemorial.
3) Write the GCC patch yourself. And I will not review it.
And yes, those are in order of decreasing preference.
