            Bug ID: 101708
           Summary: 'shader translation failed: -4' with dolphin-emu
                    ubershaders
           Product: Mesa
           Version: git

Apitrace

When using the new ubershaders branch with dolphin-emu and nouveau it will
print this error: 

nvc0_program_translate:610 - shader translation failed: -4

I have attached an apitrace showing the issue.

Note:

The exclusive ubershaders perform poorly with nouveau while the hybrid shaders
perform well. Also a later commit in the ubershaders branch will crash with
nouveau as described here.

shader failing to compile

Er, nevermind that. That crash is caused by a bug in a local WIP patch I have
(which is trying to fix spilling logic a bit).

Actually the shader that fails to compile is a simple-seeming geometry shader.

Sent a patch to make this work on GK110+ (embarrassing bug that caused us to
use fewer registers than were available).

However that doesn't fix it on fermi/kepler1.
