Has anyone gotten around to integrating the mmx bliting patches that
have been submitted to the list?

Could you refresh my memory on which message it was? I can’t seem to
find the original message with the patches.

See ya,

oops, I should have mentioned which messages.

These are the subjects:
some faster alpha blitting code.
alpha blending code with mmx1 instructions

The first one was the one I did. It’s only using gcc inline asm, as I
don’t have msvc to test with. Also it doesn’t detect if mmx is
available. So it needs someone to integrate it better.

Hi,

I might be able to do that, but not before my exams (and the associated
partying) are finished (ie not before around the 5th of July)

But before I’ll need to get my hands on your code :slight_smile:
And if you find someone else able to do that before me, no problem,
that’s fine too.

Excellent!

The code is in the emails attached to those messages, which you can find
in the archives.
