--- Comment #2 from Török Edwin edwin+mesa@etorok.net 2012-05-26 01:52:16 PDT --- Tried to bisect and I got to the commit (783e4da72aa203a645737dec81b001341951a942) that introduced GPR limit checking. Before that commit the shader compiles, but the rendered output is wrong (see #50325).
However in Mesa git master I don't see the GPR limit error. Bisecting again to see where the GPR limit message was lost I get to the point where GLSL 1.30 was enabled: 12bedaa24ba8f4cdb3f2b58482ce8f9ac5715703 is the first bad commit commit 12bedaa24ba8f4cdb3f2b58482ce8f9ac5715703 Author: Dave Airlie airlied@redhat.com Date: Sat Apr 21 10:37:08 2012 +0100
r600: enable glsl 1.30 on r700
I've done a piglit run on rv740 and confirmed no regressions.
We don't get GL3 on r700 due to transform feedback being busted still.

The problem is probably still that there are too many registers, except that message is no longer printed.
