The Go frontend for GCC Ian Lance Taylor Google iant@google.com Abstract A description of the Go language frontend for gcc. This is a new frontend which is a complete implementation of the new Go programming issues that arise when compiling the Go language, and issues with hook- ing up any frontend to the gcc middle-end. 1 Introduction Go is a new programming language designed by Robert Griesemer, Rob Pike a frontend to gcc, generally known as gccgo. A goal of the gccgo project is to be a typical gcc fron- tend. It is intended to require minimal changes to other parts of gcc. Like all gcc frontends, it
