X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1ea8d58f21a3505ec0e4dd168020c3846a1dfcc4;p=platform%2Fupstream%2Fllvm.git

[PowerPC][NFC] Convert an if/else to a conditional.

Change an if else to use a conditional which is shorter. Also name the
conditonal value to make the code clearer.
