Subject: ir_to_mesa: Don't forget to run the Mesa IR optimization passes.
X-Git-Tag: 062012170305~10660^2~517
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=28faa12dc2413d93c7f4778327a5e7c4c8f57c85;p=profile%2Fivi%2Fmesa.git

ir_to_mesa: Don't forget to run the Mesa IR optimization passes.

With how we generate assignments, the trivial copy propagation in it
is really important, and some drivers will really want the register
allocation, too.
