Subject: i965/fs: When producing ir_unop_abs of an operand, strip negate.
X-Git-Tag: mesa-7.11-rc1~2814
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ab56e3be9aae54602372427755305c354821e105;p=platform%2Fupstream%2Fmesa.git

i965/fs: When producing ir_unop_abs of an operand, strip negate.

We were returning the negative absolute value, instead of the absolute
value.  Fixes glsl-fs-abs-neg.
