--- Comment #1 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Ian Lance Taylor <i...@gcc.gnu.org>: https://gcc.gnu.org/g:8a8a7d332d5d01db5aea7336a36d9fd71a679fb1 commit r12-1913-g8a8a7d332d5d01db5aea7336a36d9fd71a679fb1 Author: Ian Lance Taylor <i...@golang.org> Date: Mon Jun 28 16:47:55 2021 -0700 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.
