compiler: in composite literals use temps only for interfaces For a composite literal we only need to introduce a temporary variable if we may be converting to an interface type, so only do it then. This saves over 80% of compilation time when using gccgo to compile cmd/internal/obj/x86, as the GCC middle-end spends a lot of time pointlessly computing interactions between temporary variables.

This is a compiler frontend for the Go programming language. The frontend was originally developed at Google, and was released in November 2009. It was originally written by Ian Lance Taylor.
It was originally written for GCC. As of this writing it only supports GCC, but the GCC support has been separated from the rest of the frontend, so supporting another compiler is feasible.
The go subdirectory holds the frontend source code. This is mirrored to the gcc/go subdirectory in the GCC repository.
The libgo subdirectory holds the library source code. This is a copy of the main Go library with various changes appropriate for this compiler. The main Go library is hosted at http://go.googlesource.com/go, in the src directory. The libgo subdirectory is mirrored to the libgo subdirectory in the gcc repository.
