[llvm-dev] Windows vs Mac/Linux distribution discrepancy

[Hans Wennborg via llvm-dev]

Hi Alex,

As others have answered already, it's a mix of technical things --
exposing everything as a DLL is problematic, and also we'd like to
keep the size of the binaries down. The current situation is that the
Windows binaries are focused on providing an LLVM toolchain by
shipping Clang, LLD, runtimes, etc. -- but not the internal tools like
opt, llc, and so on.

The recommendation is that those who need to build stuff with LLVM
rather than just use the toolchain should build it themselves.

Thanks,
Hans
