From 3eba09884e5f228d8c044c85617009e2aa7ad342 Mon Sep 17 00:00:00 2001 From: Ian Lance Taylor Date: Fri, 1 Mar 2019 01:23:09 +0000 Subject: [PATCH] cmd/go: add -O2 to invocation of gccgo When using the go tool with gccgo, this changes the default compilation to use -O2. The -gccgoflags option can be used to override this default. I think this change better corresponds to what people expect when using the go tool.
