[PATCH] D83592: [Parser] Add comment to skipped regions

[Vedant Kumar via Phabricator via cfe-commits]

vsk added a comment.

Could you add an end-to-end llvm-cov test (see e.g. compiler-rt/test/profile/Linux/coverage_ctors.cpp)? Here are some important cases I think we should check:

- `/* comment at the start of a line */ expr;`
- `expr; /* comment at the end of a line */`
- `expr; // comment at the end of a line`
- `// comment spanning entire line`

In all but the last case, llvm-cov should report an execution count for the line.



================
Comment at: clang/test/CoverageMapping/break.c:1
-// RUN: %clang_cc1 -fprofile-instrument=clang -fcoverage-mapping -dump-coverage-mapping -emit-llvm-only -main-file-name break.c %s | FileCheck %s
+// RUN: sed 's/\/\/.*//' %s > %T/%basename_t && %clang_cc1 -fprofile-instrument=clang -fcoverage-mapping -dump-coverage-mapping -emit-llvm-only -main-file-name break.c %T/%basename_t | FileCheck %s
 
----------------
Could you introduce a lit substitution in clang/test/lit.cfg.py for this (say, '%strip_comments'?), so that there's just one copy of the sed command?
