[cfe-dev] LibC++ v4.0 testing and exceptions

[Martin J. O'Riordan via cfe-dev]

Others are failing because of 'align_val_t' - it looks to be like these are
C++17 tests, but the tests are not being disabled when I use '-std=c++14'.
My target it cross-compiled and out-of-tree, so the CMake based
configuration for the tests is not useful.  Previously the tests
automatically excluded themselves based on the STDC++ version chosen, is
this intended for the current tests?

 

Thanks,

I have started testing our LibC++ v4.0 implementation, and I am seeing a
very large number of tests failing because the test uses 'try' or some other
EH related feature.  However, my platform does not (and cannot) support
Exception Handling.  Previous releases used '_LIBCPP_NO_EXCEPTIONS' in the
tests to determine if the implementation supported EH or not, but this seems
not to be the case for the most recent v4.0 RC1 release.

 

At the moment this appears to be the cause of 309 regressions I am seeing.
Has LibC++ dropped support for platforms that do not support EH?

 

Thanks,
