My Athlon-xp does NOT have sse2 In make.conf I have (for my Athlon4 2400+): CFLAGS="-O2 -march=athlon-4 -mfpmath=sse -pipe -mno-sse2" But when I emerge mesa-progs I see: make -j1 glxgears i686-pc-linux-gnu-gcc -I../../include -I/usr/X11R6/include -Wall -Wmissing-prototypes -std=c99 -ffast-math -O2 -march=athlon-4 -mfpmath=sse -pipe -mno-sse2 -m32 -mmmx -msse -msse2 -D_POSIX_SOURCE -D_POSIX_C_SOURCE=199309L -D_SVID_SOURCE -D_BSD_SOURCE -D_GNU_SOURCE -DPTHREADS -DUSE_EXTERNAL_DXTN_LIB=1 -DIN_DRI_DRIVER -DGLX_DIRECT_RENDERING -DGLX_INDIRECT_RENDERING -DHAVE_ALIAS -DHAVE_POSIX_MEMALIGN -DUSE_X86_ASM -DUSE_MMX_ASM -DUSE_3DNOW_ASM -DUSE_SSE_ASM -fno-strict-aliasing -Wl,-O1 glxgears.c -L../../lib -lGL -lm -lX11 -lpthread -o glxgears >>> Source compiled. where the later -msse2 overrides my -mno-sse2 The resulting glxgears crashes with "illegal instruction" Reproducible: Always Steps to Reproduce: 1. in make.conf - CFLAGS="-O2 -march=athlon-4 -mfpmath=sse -pipe -mno-sse2" 2. emerge mesa-progs 3. /usr/bin/glxgears Actual Results: illegal instruction Expected Results: New window with rotating gears!

Please provide your emerge --info. Thanks

Haha! I can confirm this also... i installed a new gentoo on a old k6-3 box with a ati rage 128 and was wondered about this error! this cpu has also no sse and sse2. but other 3d apps works... because i have emerged mesa with use _pic_.

CONFIRMED. The -msse2 comes from configs/linux-dri-x86. BTW: There is other stuff that should be whiped as well. Regards, Bodo
No one ever posted a version that his affects. The build process for 8.0.1 looks nothing like what you describe, and I don't see any evidence of -msse flags being added, so I presume the older (affected) version was 7.x, which is no longer in the tree. Closing.
