Important note: The mull package is now replaced with a separate package for each supported LLVM version, e.g. mull-8, mull-13, etc. The mull package won't be updated!

Important note: The binaries mull-cxx and mull-runner are now named after the corresponding LLVM version, e.g. mull-cxx-8, mull-runner-13, etc.

  • Publish mull-${LLVM_VERSION} package instead of mull package 904
  • Include LLVM version into the package/binary name 904
