Hello,

I'm currently trying to run GTA V on Wine with radeonsi. After forcing a
4.5compat context, GLSL 450 and commenting out this block
https://github.com/mesa3d/mesa/blob/2c9ac0bc6377800ac5110c781dfabea68efa79a5/src/mesa/main/getstring.c#L140
the game boots. I'm eventually able to see the loading screen after applying a
Wine workaround.

However, when the game actually starts, I'm hitting this error:

> LLVM ERROR: Cannot select: 0x7f1c482ed398: f32 = sign_extend 0x7f1c482ecd18
>    0x7f1c482ecd18: i1,ch = CopyFromReg 0x7f1c48299c08, Register:i1 %vreg62
>    0x7f1c48159298: i1 = Register %vreg62
> In function: main

Here's the apitrace: http://dl.free.fr/mjmArhBAy
None of the workarounds I mentioned are needed to trigger the bug. `apitrace
replay wine64-preloader.trace` should work with mesa-git.

Thanks,
libcg
