    r600g/llvm: tgsi to llvm emits store.swizzle intrinsic for vs/fs output

Enemy territory quake wars locks GPU as soon as it loads.

Doesn't happen with R600_LLVM=0, doesn't happen on the commit before this.

As far as I can tell, all shaders end with an export instruction, with
EndOfProgram bit set. I suspect an issue with number of color buffer export
involved.

Can you apply this patch and report if the game still locks the gpu ?

--- Comment #9 from Alex Deucher <agd5f@yahoo.com> ---
Regarding the conversation on IRC, the vertex shader has to export at least one
generic param (not counting special exports like position).  So if the vertex
shader doesn't export any params, you need a dummy one.

Can you test with this new patch ? (Remove the previous one)
It adds dummy export to vs outputs
