I'm getting trouble using clang with compiled libc++ on MSVC.

1. why clang chooses link over lld-link by default? I don't really wish to write -fuse-ld=lld-link every single time I build something.
2. why lld-link doesn't search inside default lib directory? I need to manually show him where it is although I put that binary in <LLVM root>\lib\
3. why clang invokes linker with -defaultlib:libcmt? I mean libc++ build guide under MSVC produces -MD version of either libc++.lib or c++.lib
4. Since (3), it's not possible to build anything without splitting compiler and linker calls - clang by default produces -MT versions of objects and linker fails to compose it with -MD library. No, -dynamic flag does not help either. Any fixes to these? Can I config clang somehow except --config option? -------------- next part -------------- An HTML attachment was scrubbed...
