Just for the record: in a separate exchange it was realized that: A) This was for a context of a buildworld that was built via gcc 4.2.1 and being able to use clang in such a context. B) This is insufficient to fully fix a buildworld that was built via clang and then use either clang or gcc (such as gcc7) to generate code bound to the system libc++ and libcxxrt for code that throws C++ exceptions. A clang-based builworld results in problems in libc++ and/or libcxxrt for handling thrown C++ exceptions. === Mark Millard markmi at dsl-only.net _______________________________________________ freebsd-toolchain@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-toolchain To unsubscribe, send any mail to "freebsd-toolchain-unsubscr...@freebsd.org"
