Author: rupprecht Date: Thu Jun 20 15:35:52 2019 New Revision: 363996 URL: http://llvm.org/viewvc/llvm-project?rev=363996&view=rev Log: [CodeGen][test] Use FileCheck variable matchers for better test support
Summary: Depending on how clang is built, it may discard the IR names and use names like `%2` instead of `%result.ptr`, causing tests that rely on the IR name to fail. Using FileCheck matchers makes the test work regardless of how clang is built. This test passes with both `-fno-discard-value-names` and `-fdiscard-value-names` to make sure it passes regardless of the build mode.
