Subject: broadcom/vc5: Set the snorm/unorm packing functions to be lowered.
X-Git-Tag: upstream/18.1.0~4900
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a48a38937cabad68fcda23defc2c9d4145d267d4;p=platform%2Fupstream%2Fmesa.git

broadcom/vc5: Set the snorm/unorm packing functions to be lowered.

We don't have native instructions for them, so set up the lowering.  Once
we support the bfi instructions that get generated, they should start
actually working.
