URL: https://github.com/llvm/llvm-project/commit/47eb8b43c99034119ca93f16179dc6003c68a20b DIFF: https://github.com/llvm/llvm-project/commit/47eb8b43c99034119ca93f16179dc6003c68a20b.diff LOG: [UnitTests] Enable PCH (#191402) I originally didn't enable PCH for unit tests, because I intended to build a gtest PCH. But while gtest.h is slow, having many large standard library headers already pre-compiled via the LLVMSupport PCH already helps a lot, leaving ~250ms for parsing gtest.h (+ a fair amount of time for template instantiation). Additionally, for unit tests that include IR or AST headers, re-using the PCHs that include these is more beneficial than gtest.h. Therefore, no longer disable PCH on unit tests.
