From 798ace2e58a4bbe607d907a9efc7388e221dc431 Mon Sep 17 00:00:00 2001 From: Peter Collingbourne Date: Thu, 16 Oct 2014 22:48:02 +0000 Subject: [PATCH] Initial version of Go bindings. This code is based on the existing LLVM Go bindings project hosted at: https://github.com/go-llvm/llvm Note that all contributors to the gollvm project have agreed to relicense their changes under the LLVM license and submit them to the LLVM project.
