Subject: [TargetLibraryInfo] Correctly handle sqrt*_finite
X-Git-Tag: upstream/15.0.7~30568
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6185ad03f1085911812e8244a4994a04c62e19b6;p=platform%2Fupstream%2Fllvm.git

[TargetLibraryInfo] Correctly handle sqrt*_finite

Other <math>_finite calls are marked as unavailable except on GNU/Linux;
it looks like the sqrt set was just overlooked.
