From: Rahul Joshi Date: Tue, 28 Jul 2020 17:29:43 +0000 (-0700) Subject: [MLIR] Add unit test for tblgen Op build methods X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0b161def6cacff1a63d3cf1a1efe95b550814d7a;p=platform%2Fupstream%2Fllvm.git [MLIR] Add unit test for tblgen Op build methods - Initiate the unit test with a test that tests variants of build() methods generated for ops with variadic operands and results. - The intent is to migrate unit .td tests in mlir/test/mlir-tblgen that check for generated C++ code to these unit tests which test both that the generated code compiles and also is functionally correct.
