Subject: mark getTargetTransformInfo and getTargetIRAnalysis as const
X-Git-Tag: upstream/15.0.7~15245
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c4b1a63a1b0338d5b3a66e2c039a67107b1a2416;p=platform%2Fupstream%2Fllvm.git

mark getTargetTransformInfo and getTargetIRAnalysis as const

Seems like this can be const, since Passes shouldn't modify it.
