在哪里可以获得go-lang源代码的C版本？

Question

As I know, go-lang is written by C at the beginning, and now it is written by itself. I want to figure out some fundamental implementations of go-lang, such as multi-return-value-of-function, which probably use structure I guess.

But now the go-lang version of go-lang source code has conceal these details, so where can I get the C version of go-lang source code (history version)? I've checked golang.org, nothing found.

Thanks.

Go 1.5 Release Notes

The compiler and runtime are now written entirely in Go (with a little assembler). C is no longer involved in the implementation, and so the C compiler that was once necessary for building the distribution is gone.

Therefore, check out the source code for previous release: release-branch.go1.4.

For example,

git clone https://go.googlesource.com/go --branch release-branch.go1.4 --single-branch go1.4
