llgo is a compiler for Go, written in Go, and using the LLVM compiler infrastructure.

llgo is a fledgling, and is being developed primarily as an educational exercise. It is not presently useful for real work. Progress will be reported at http://blog.awilkins.id.au.

The recommended way to install llgo is to use go get. You'll need to set a couple of environment variables first:

export CGO_CFLAGS="`llvm-config --cflags`"
export CGO_LDFLAGS="`llvm-config --ldflags` -Wl,-L`llvm-config --libdir` -lLLVM-`llvm-config --version`"
go get github.com/axw/llgo/llgo

You must have LLVM 3.2 or better in your path. You can also use latest development version of LLVM, and build it from LLVM SVN repository, just be sure to pass --enable-shared to LLVM configure during build.

Note: llgo requires Go 1.0.3 or Go tip before rev 2e2a1d8184e6 (last known good rev is rev 6e9d872ffc66).

First compile the runtime support packages using cmd/llgo-dist command, just run llgo-dist.

Currently there is just a compiler which produces LLVM bitcode, and there is no integration with the go command or cgo, etc. To compile a Go source file, simply run llgo <file.go>, which will emit LLVM bitcode to stdout. To produce human-readable LLVM assembly code, supply an additional -dump command line argument before <file.go>.

First make sure you have LLVM 3.2+ installed, then re-install gollvm package with the tag llvmsvn.

go clean -i github.com/axw/gollvm/llvm
go install -tags llvmsvn github.com/axw/gollvm/llvm
go test -i github.com/axw/llgo/llgo
go test -v github.com/axw/llgo/llgo
