Ok, I suppose I can fix that :) But first I need to understand how the whole
thing is supposed to work... It's not very clear between python stuff
generating asm stubs, magic macros, etc etc... (btw. I think there are bugs
there but I'll have to dbl check when I understand what the stuff is actually
supposed to do in the first place).
Can somebody explain me how it works without the asm stuff (the pure C stuff)
and what the "optimized" version is supposed to do ? I have enabled
-DGLX_USE_TLS and the resulting stubs look not too bad, but I could probably
make them a bit better with asm (like doing a proper tail call).
However, I suppose that if I could acutally generate code at runtime, I could
do even better and generating a branch island that loads the absolute address
of the target and branch to it (basically about 4 or 5 insns in 32 bits, maybe
a bit more in 64 bits). But first I need to get a bit more familiar with how
this all fits together in the mesa source, so far I'm just confused :)
