Braid Native

This is the experimental native backend for Braid. It compiles to LLVM. It resides in a separate directory so the main compiler can avoid a dependency on the native LLVM library.

To use this backend, install its dependencies:

$ cd native
$ yarn

The driver for the native compiler is braidnc, at build/native/braidnc.js.

You will need to have the LLVM dynamic library on your linker path. For example, for my copy of LLVM installed via Homebrew, I had to do this:

$ export LD_LIBRARY_PATH=`brew --prefix llvm`/lib

By default, braidnc writes LLVM IR to stdout. To dump bitcode to a file, use the -o option:

$ braidnc -o program.bc program.ss

Then, an easy way to compile this to native code is using clang:

$ clang program.bc
% ./a.out
