New Revision: 367304
URL: https://svnweb.freebsd.org/changeset/base/367304
Log:
Add WITH_LLVM_CXXFILT option to install llvm-cxxfilt as c++filt
Since elftoolchain's cxxfilt is rather far behind on features, and we
ran into several bugs, add an option to use llvm-cxxfilt as an drop-in
replacement.
It supports the same options as elftoolchain cxxfilt, though it doesn't
have support for old ARM (C++ Annotated Reference Manual, not the CPU)
and GNU v2 manglings. But these are irrelevant in 2020.
Note: as we already compile the required libraries as part of libllvm,
this will not add any significant build time either.
