llgo is a Go frontend for LLVM, written in Go.
llgo is under active development. It compiles and passes most of the standard library test suite and a substantial portion of the gc test suite, but there are some corner cases that are known not to be handled correctly yet. Nevertheless it can compile modestly substantial programs (including itself; it is self hosting on x86-64 Linux).
Progress will be reported on the mailing list.
To install llgo, use make:
go get github.com/go-llvm/llgo
cd $GOPATH/src/github.com/go-llvm/llgo
make install prefix=/path/to/prefix
You may need to build LLVM. See GoLLVM's README.md for more information.
llgo requires Go 1.3 or later.
We install two binaries to $prefix/bin: llgo and llgo-go.
llgo is the compiler binary. It has a command line interface that is intended to be compatible to a large extent with gccgo.
llgo-go is a command line wrapper for go. It works like the regular go command except that it uses llgo to build.
