Bug ID: 42230
Summary: r362459's unit test hits a bug in MSVC that causes it
to fail to build
Product: clang
Version: trunk
Hardware: PC
OS: Windows XP
Status: NEW
Severity: normal
Priority: P
Component: Frontend
Assignee: unassignedclangb...@nondot.org
Reporter: erich.ke...@intel.com
CC: llvm-bugs@lists.llvm.org, neeil...@live.com,

As RKSimon mentions here: https://reviews.llvm.org/rL362459#change-mx46UHL2Colz
Compiling check-all on MSVC with Werror causes the unit test
DependencyDirectivesSourceMinimizerTest.cpp to fail to build due to the comma
issue mentioned.
This is actually because of the MSVC bug listed here:
https://developercommunity.visualstudio.com/content/problem/67300/stringifying-raw-string-literal.html
Here is a minimization of this issue here: https://godbolt.org/z/RFcVcb .
Change one of the outputs to use /E to see the mess that MSVC makes out of
this while stringifying them :)
I suspect the MinimizeSourceToDependencyDirectivesTest, RawStringLiteral test
might need disabling in the meantime.
