tre

A LLVM backed Go compiler.

tre is built in Go and can compile a subset of Go code to LLVM IR. Clang is used to compile the IR to an executable.

Building

# Build tre and run a test program
go build -i github.com/zegl/tre/cmd/tre && ./tre tests/tests/fib.tre && ./output-binary

Example

Example program that calculates the fibonacci sequence.

func fib(num int) int {
    if num < 2 {
        return num
    }

    return fib(num-2) + fib(num-1)
}

func main() {
    printf("%d\n", fib(34))
}

More examples of what's possible can be found in the compiler testdata.
