I have the assembly language working with the newest Mesa. I just
added a new file, x86.c, which defines gl_init_x86_asm_transforms(),
which replaces the entries in gl_transform_tab and gl_clip_tab that
have assembly language equivalents with pointers to the asm functions.
It still has some bugs to fix before I commit it.
One new thing about the assembly code that may be bad is that it now
uses m4 macros. As long as a pre-expanded version is included, is
that OK?
