So, we should really fix this. The two options are :
- Keep a different calling convention under linux (cdecl by default,
which requires saving esi by hand in the shader) and apply Victor's
patch which saves restores this register
- Use the same calling convention on all platforms, that is change

Here is my first patch for Nouveau project: a fix for 3D software
rendering using SSE2 instruction set.
The problem is that Gallium doesn't save/restore used registers
(eax, edx, ecx, esi in my case). So I added push/pop in
tgsi_emit_sse2().
Doesn't the ABI say that those are scratch
