compiler-opt-info2 v0.0.3

A fork of jaredwy's https://github.com/jaredwy/compiler-opt-info, as it seemed unmaintained and a bug needed fixing.

Original readme:

Currently provides a stream transofmer for the output of a opt.yaml file from LLVM.

See test/test.js for an example of how to use it.

See types.ts for the output format (currently just matches the LLVM output).
