Subject: ir_reader: Free memory for S-Expressions earlier.
X-Git-Tag: mesa-7.9-rc1~1173^2~610
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=78062273de65bf8133f2550aa2a26040a82a65aa;p=platform%2Fupstream%2Fmesa.git

ir_reader: Free memory for S-Expressions earlier.

There's no point in keeping it around once we've read the IR.

Also, remove an unnecessary talloc_parent call.
