Hello! I am seeing a downstream build failure on Mac as a result of your changes:

We also encounter a build failure on the Mac related to above but in a different file:
clang/lib/CodeGen/CGStmtOpenMP.cpp:1916:3: error: too few template arguments for class template 'SmallVector'
SmallVector<llvm::Value *> EffectiveArgs;
clang/include/clang/Basic/LLVM.h:35:42: note: template is declared here

Diff after rebase.

I can fix this locally to get our builds running, but is it possible that you could commit a fix upstream? I appreciate it, thanks!

In the description, you refer to fallback_malloc.cpp "The code in libcxxabi/src/fallback_malloc.cpp looks like it could be simplified after this change -- I purposefully did not simplify it further to keep this change as straightforward as possible, since it is touching very important parts of the library."

Looks like _LIBCPP_HAS_NO_THREADS is being set for libcxxabi, and the build now fails with this change:
Bump format version and add preliminary documentation for CoverageMappingFormat, SourceBasedCodeCoverage, and llvm-cov tool

Just checking in again -- is there interest in completing this review? I'd be happy to assist, or I could post an updated version of it.

@eastig I tried this experimental patch in our system, and it definitely brings highly significant improvement to coremark. When do you expect to post a version for reviewing -- what will the differences be?

1.) Fix a defect in the CGExprScalar.cpp code to instrument RHS condition for branch coverage that resulted in a RHS condition as being evaluated twice. This is incorrect behavior since a condition may have side-effects. I also added a test.
2.) Back out unintended whitespace/punctuation (please let me know if I overlooked anything).
3.) Rebase against updated upstream.

There exist downstream ARM compilers that doesn't support ARM64 and fail with Inputs/arm_function_name.ll. You should consider guarding arm64 specific tests.

- Rename isLeafCondition() to isInstrumentedCondition() and rephrase associated comments
- Add branch regions on C++ range-based loops

I just ran into what I think may be the same issue here in that llvm-objdump seems to ignore machine data (endian, possible mode) when disassembling ARM instructions on ARMv7. Is there any interest in completing this review and committing this particular fix (and making sure it works for ARMv7 as well)?

Updating for formatting and comments (and some test adjustments after rebase). Bypassing logical-NOT operators in CodeGenFunction::isLeafCondition(), which checks the condition for the presence of logical-AND and logical-OR. (this can be further expanded, if necessary)

Thank you for your comments on the review! I will respond soon; also have been swamped this week.

It looks like clang/test/Profile/Inputs/c-general.profdata.v5 is being read as v6 rather than v5. Can you double check?

clang/test/CodeGen/sanitize-coverage.c is also failing our downstream embedded ARMv7 validations.

This test is still failing on the arm bots and also with my downstream ARM compiler validation.

Hello! Your test specifically looks for "248", which is failing with my downstream embedded ARM compiler (we produce "249"); other similar tests that I've looked at simply ignore this value. Is there a reason why you need to check it specifically?
Jan 10 2020
Sorry, we just saw your commit to fix. We are OK. Thanks!
We maintain a downstream embedded ARM compiler, and this test is failing for us now because it assumes a 64bit size_t in the first CHECK line of the mempcpy-libcall.c. Because this is testing a GNU specific builtin, should it be specific to only targets that support that? Or should it be extended to support 32bit size_t?
