[PATCH] D85802: [clang] Add -fc++-abi= flag for specifying which C++ ABI to use

[John McCall via Phabricator via cfe-commits]

rjmccall added a comment.

It's certainly possible that other targets will want to support multiple C++ ABIs in the future, but it's okay for us to design things around the situation we've got today.  A lot of these "ABIs" are just target-specific variants; if it simplifies code to just make ABI queries just be target queries instead of abstracting the target C++ ABI, and the resulting burden on targets with multiple supported ABIs is very small, that seems like an acceptable trade-off.  If things change and we get a lot of targets asking to support multiple ABIs, there's no reason we can't revisit this decision.
