Subject: Adding tests for -ast-dump; NFC.
X-Git-Tag: llvmorg-8.0.0-rc1~3186
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e47b3669002affb663f76e4a43453b56d3839ec7;p=platform%2Fupstream%2Fllvm.git

Adding tests for -ast-dump; NFC.

This adds tests for GenericSelectionExpr; note that it points out a minor whitespace bug for selection expression cases.
