From c2047754c300b68c05d65faa8dc2925fe67b71b4 Mon Sep 17 00:00:00 2001 From: Ian Lance Taylor Date: Sat, 14 Jan 2017 00:05:42 +0000 Subject: libgo: update to Go 1.8 release candidate 1 Compiler changes: * Change map assignment to use mapassign and assign value directly. * Change string iteration to use decoderune, faster for ASCII strings. * Change makeslice to take int, and use makeslice64 for larger values. * Add new noverflow field to hmap struct used for maps. Unresolved problems, to be fixed later: * Commented out test in go/types/sizes_test.go that doesn't compile. * Commented out reflect.TestStructOf test for padding after zero-sized field. Reviewed-on: https://go-review.googlesource.com/35231 gotools/: Updates for Go 1.8rc1. * Makefile.am (go_cmd_go_files): Add bug.go. (s-zdefaultcc): Write defaultPkgConfig. * Makefile.in: Rebuild.
