[Mesa-dev] [PATCH] i965/fs: Use fs_reg for CS/VS atomics pixel mask immediate data

2015-02-20 Thread Jordan Justen 
The brw_imm_ud will yield a HW_REG which then will introduce a barrier
for certain optimization opportunities.

No piglit regressions seen with gen8 (simd8vs).

It might be a good idea to make the fs_reg(struct brw_reg) explicit to
prevent this kind of mistake from happening.

By the way, there are some more in gen6_gs_visitor.cpp if you'd like
to clean those up as well.
