Author: Raul Tambre Date: 2020-09-18T20:51:55+03:00 New Revision: a1aa330b202f97ecd243ea9ef0c7ac00a80ea653
URL: https://github.com/llvm/llvm-project/commit/a1aa330b202f97ecd243ea9ef0c7ac00a80ea653 DIFF: https://github.com/llvm/llvm-project/commit/a1aa330b202f97ecd243ea9ef0c7ac00a80ea653.diff LOG: [Sema] Handle objc_super special lookup when checking builtin compatibility objc_super is special and needs LookupPredefedObjCSuperType() called before performing builtin type comparisons. This fixes an error when compiling macOS headers. A test is added.
