patches to the author.
Notes on assembly language optimizations:
When using the old-style Makefiles, you can specify a configuration
that uses X86 assembly language optimizations (linux-3dnow for example).
The detection of MMX, 3DNow!, PIII/SSE, etc capability is done at
runtime. That means you can compile Mesa for 3DNow! optimizations
even if you don't have an AMD CPU.
However, your Linux binutils and assembler must understand the
special instructions in order to compile them. If you have
compilation problems, try upgrading your binutils.
Header and library files:
After you've compiled Mesa and tried the demos I recommend the following
procedure for "installing" Mesa.
