[FileCheck] Make FILECHECK_OPTS useful for its test suite Without this patch, `FILECHECK_OPTS` isn't propagated to FileCheck's test suite so that `FILECHECK_OPTS` doesn't inadvertently affect test results by affecting the output of FileCheck calls under test. As a result, `FILECHECK_OPTS` is useless for debugging FileCheck's test suite. In `llvm/test/FileCheck/lit.local.cfg`, this patch provides a new subsitution, `%ProtectFileCheckOutput`, to address this problem for both `FILECHECK_OPTS` and the deprecated `FILECHECK_DUMP_INPUT_ON_FAILURE`. The rest of the patch uses `%ProtectFileCheckOutput` throughout the test suite Fixes PR40284. Reviewed By: probinson, thopre Differential Revision: https://reviews.llvm.org/D65121

[FileCheck] Fix a bug that cause FileCheck to misidentify check-prefix FileCheck should check to make sure the prefix was found, and not a word containing it (e.g -check-prefix=BASEREL shouldn't match NOBASEREL). Patch by Ron Ofir. llvm-svn: 188221

[FileCheck] Make invalid prefix diagnostics more precise This will prove especially helpful after D79276, which introduces comment prefixes. Specifically, identifying whether there's a uniqueness violation will be helpful as prefixes will be required to be unique across both check prefixes and comment prefixes. Also, remove a related comment about `cl::list` that no longer seems relevant now that FileCheck is also a library.

[FileCheck] Support comment directives Sometimes you want to disable a FileCheck directive without removing it entirely, or you want to write comments that mention a directive by name. The `COM:` directive makes it easy to do this. For example, you might have: ``` ; X32: pinsrd_1: ; X32: pinsrd $1, 4(%esp), %xmm0 ; COM: FIXME: X64 isn't working correctly yet for this part of codegen, but ; COM: X64 will have something similar to X32: ; COM: ; COM: X64: pinsrd_1: ; COM: X64: pinsrd $1, %edi, %xmm0 ``` Without this patch, you need to use some combination of rewording and directive syntax mangling to prevent FileCheck from recognizing the commented occurrences of `X32:` and `X64:` above as directives. Moreover, FileCheck diagnostics have been proposed that might complain about the occurrences of `X64` that don't have the trailing `:` because they look like directive typos: <http://lists.llvm.org/pipermail/llvm-dev/2020-April/140610.html> I think dodging all these problems can prove tedious for test authors, and directive syntax mangling already makes the purpose of existing test code unclear. `COM:` can avoid all these problems. This patch also updates the small set of existing tests that define `COM` as a check prefix: - clang/test/CodeGen/default-address-space.c - clang/test/CodeGenOpenCL/addr-space-struct-arg.cl - clang/test/Driver/hip-device-libs.hip - llvm/test/Assembler/drop-debug-info-nonzero-alloca.ll I think lit should support `COM:` as well. Perhaps `clang -verify` should too. Reviewed By: jhenderson, thopre Differential Revision: https://reviews.llvm.org/D79276
