From 1b09d430678d4a6f73b2443463d11f75851aba8a Mon Sep 17 00:00:00 2001 From: Russ Cox Date: Fri, 16 Oct 2020 00:49:02 -0400 Subject: all: update references to symbols moved from io/ioutil to io The old ioutil references are still valid, but update our code to reflect best practices and get used to the new locations. Code compiled with the bootstrap toolchain (cmd/asm, cmd/dist, cmd/compile, debug/elf) must remain Go 1.4-compatible and is excluded. Also excluded vendored code. For #41190.
