Hi,

just played with 3D support for my Matrox G400. So I compiled
glx-SNAP-20000107 together with MesaLib-3.1 and noticed the following:

-O3 -fomit-frame-pointer -funroll-loops -ffast-math -mieee-fp:

crash of the glx-Module (SIGSEGV)


-O3 -fno-compare-elim -fomit-frame-pointer -funroll-loops -ffast-math
-mieee-fp:

works

-O6 -fno-compare-elim -funroll-loops -ffast-math -mieee-fp:

system freezes


-O6 -fno-compare-elim -fno-do-offload -funroll-loops -ffast-math
-mieee-fp:

works


Any fixes?

ron
