I believe that's a red herring. It's caused by our use of -flto in the build,
meaning the use of AVX in one place "spills" to surrounding code that is
otherwise innocent.
Without -flto, the next instruction to crash happens inside
GlobalKnobs::GlobalKnobs(). I see this function (in fact, the entire
gen_knobs.cpp file) present in at least two libraries: libmesaswr and
libswrAVX. That is,
both./src/gallium/drivers/swr/rasterizer/codegen/.libs/libmesaswr_la-gen_knobs.o
and ./src/gallium/drivers/swr/rasterizer/codegen/.libs/libswrAVX_la-gen_knobs.o
exist and contain this function. And BOTH files have AVX instructions. I can
see the -mavx flag in the build.
Was this intended?
