emllvm

LLVM and Clang ported to Emscripten

Instructions

1. Install prerequisites.

   • Emscripten
   • Clang - emllvm has been tested against Clang 3.9 and currently assumes that Clang binaries are available under /usr/bin and has been tested against Clang 3.9.
   • CMake - Currently, version 3.4.3 or newer is required. See LLVM documentation for details.

2. Optionally, create a symlink to emsdk-portable (or place the emsdk-portable directory in the emllvm directory) so that the build script can automatically find it.

3. Run the build script.

   cd emllvm
   ./build.sh
