[PATCH] D11522: [libc++abi] Allow use just compiled clang++ for tests

[Renato Golin]

rengolin created this revision.
rengolin added reviewers: mclow.lists, jroelofs, theraven.
rengolin added a subscriber: llvm-commits.
rengolin set the repository for this revision to rL LLVM.

Currently, the tests assume the system compiler is the one we want
to test, but if we build libcxxabi together with LLVM+Clang, it'll
get the wrong compiler.

This patch allows us to test if we have clang++ in our /bin directory,
and if so, use it.
