GitHub CI based builds of LLVM libraries, compatible with the Swift runtime.
These builds
contain a set of libraries suitable for compiler
development, and a very minimal set of tools such as llvm-config and
lld. If you're looking for a compiler binary (e.g. clang), look
elsewhere!
Both the “Debug” and “MinSizeRel” builds have assertions enabled; without assertions, during development it's too easy to violate LLVM's preconditions (some of which are undocumented or incorrectly documented)
Swift compatibility is mostly irrelevant except when it comes to
Windows, where these builds of LLVM always link against a release-mode
multithreaded DLL C runtime and have iterator debugging disabled
(_ITERATOR_DEBUG_LEVEL=0) for C++.
