[PATCH] D138847: MC/DC in LLVM Source-Based Code Coverage: llvm-cov visualization

[Alan Phipps via Phabricator via llvm-commits]

alanphipps updated this revision to Diff 557511.
alanphipps added a comment.

Eliminated -Wswitch build issues in CoverageMappingGen.cpp. The actual code for this originally ended up in D138849 <https://reviews.llvm.org/D138849> after I split up the patches, but it should've been included in this one.

Fixed windows test failures, which were due to relative coverage compilation path inconsistencies in the generated object files used in the test cases.  I addressed this by using `-fcoverage-compilation-dir` and verified the tests now pass on windows, linux, and mac.

Also rebased.
