http://reviews.llvm.org/D19133 causes a regression in mesa's llvmpipe driver on
ppc64le.

The regression is detected by running piglit test suite with mesa master and
llvm master.

The following two tests fail with D19133 (and pass without it):

fbo-blending-formats GL_EXT_texture_snorm -auto -fbo
max-samplers border -auto -fbo

Forgot to mention you need to enable VSX in mesa's code to see this issue. VSX is disabled by default because of previous LLVM VSX bugs (which are already fixed). It is still disabled because of this bug.

Is this bug still valid? Does llvmpipe still have issues with VSX that appear only with this patch?
