2019-10-10all: remove nacl (part 3, more amd64p32)Brad Fitzpatrick
Part 1: CL 199499 (GOOS nacl) Part 2: CL 200077 (amd64p32 files, toolchain) Part 3: stuff that arguably should've been part of Part 2, but I forgot one of my grep patterns when splitting the original CL up into two parts. This one might also have interesting stuff to resurrect for any future x32 ABI support.

2019-04-30cmd/go,cmd/internal/sys,cmd/link: skip Go build ids for externally linked toolsElias Naur
cmd/go already skips build ids on Android where buildmode=pie is forced. Expand the check to all externally linked tools. Necessary for self-hosted iOS builds where PIE is not forced but external linking is.

2019-04-08cmd/go/internal/work: make toolchain builds reproducible when buildmode=pieElias Naur
When buildmode=pie, external linking is forced, and our toolchain build id will be included in the external build id, resulting in the building of a toolchain tool will never reach a fixed point id. More importantly, this change will make make.bash converge on self-hosted Android builds (Android refuses to run non-PIE executables).

2018-11-13cmd,runtime: enable race detector on arm64Fangming.Fang
Changes include: 1. enable compiler option -race for arm64 2. add runtime/race_arm64.s to manage the calls from Go to the compiler-rt runtime 3. change racewalk.go to call racefuncenterfp instead of racefuncenter on arm64 to allow the caller pc to be obtained in the asm code before calling the tsan version 4. race_linux_arm64.syso comes from compiler-rt which just supports 48bit VA, compiler-rt is fetched from master branch which latest commit is 3aa2b775d08f903f804246af10b Fixes #25682 Change-Id: I04364c580b8157fd117deecae74a4656ba16e005 Reviewed-on: https://go-review.googlesource.com/c/138675 Run-TryBot: Cherry Zhang <cherryyz@google.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Cherry Zhang <cherryyz@google.com>
2018-08-21cmd/compile: only support -race and -msan where they workIan Lance Taylor
Consolidate decision about whether -race and -msan options are supported in cmd/internal/sys. Use consolidated functions in cmd/compile and cmd/go. Use a copy of them in cmd/dist; cmd/dist can't import cmd/internal/sys because Go 1.4 doesn't have it.

2016-04-07cmd: add new common architecture representationMatthew Dempsky
Information about CPU architectures (e.g., name, family, byte ordering, pointer and register size) is currently redundantly scattered around the source tree. Instead consolidate the basic information into a single new package cmd/internal/sys. Also, introduce new sys.I386, sys.AMD64, etc. names for the constants '8', '6', etc. and replace most uses of the latter. The notable exceptions are a couple of error messages that still refer to the old char-based toolchain names and function reltype in cmd/link. Passes toolstash/buildall.
