How to disable AVX instruction set in opengl32.dll compilation

[fabceolin]

I am getting illegal instruction when I trying to use opengl32.gll
From depends_x64
00:00:21.282: Second chance exception 0xC000001D (Illegal Instruction) occurred in "%DIR%\OPENGL32.DLL" at address 0x00007FF975EDB0E3 by thread 1.

Here I saw about AVX instruction set:

How can I change the instruction set in opengl32.dll compilation? (maybe removing the AVX instruction set)

I think you need to ask for help on Mesa-dev mailing list.
What program it happens with?
Did you use my build or you built it yourself?
Does your CPU supports AVX?
Did you opt in to build OpenSWR?

I tried your build first, without success and now I am trying to build myself.

We are testing using our software, based in VTK.
I select to build the openswr. I am using the same kvm machine to build and test.

The CPU supports AVX2 but I didn't seed in AVX here:

AVX2 without AVX is definitely an unsupported configuration. I have doubts this will be fixed by Mesa3D developers. Sorry, but all you can do is build it yourself on that awkward configuration of yours and see what happens.

The build environment I use does have AVX support. It lacks AVX2 support though.
