Hi Michael,
I would like an update on the review process.
The patches add missing clobbers (mmx, xmm and memory) to some assembly chunks.
Note that looking at the commit history, some other chunks have already been
patched in such a way by the past.
Moreover, as far as I know, the patches from 1 to 14 passed the fate tests,
both on my computer and on patchwork.
Let me know if you have any remark on them.
By the way, I have a deadline that comes and I would really appreciate to see
the patches applied by wednesday night. Do you think it would be possible?
Regards,
Frédéric
