From: Uday Bondhugula Date: Mon, 13 Apr 2020 14:00:35 +0000 (+0530) Subject: [MLIR] NFC clean up simplify-affine-structures test case X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=500e03881bed99ffdfcecbfa47d898067a535215;p=platform%2Fupstream%2Fllvm.git [MLIR] NFC clean up simplify-affine-structures test case NFC clean up for simplify-affine-structures test cases. Rename sets better; avoid suffix numbers; move outlined definitions close to use. This is in preparation for other functionality updates.
