2022-05-04cmd,runtime: enable race detector on s390xIlya Leoshkevich
LLVM has SystemZ ThreadSanitizer support now [1], this patch integrates it with golang. The biggest part is the glue code in race_s390x.s, which is derived from race_arm64.s, and then the support needs to be enabled in four places.

2021-02-23runtime: enable race detector on openbsd/amd64Joel Sing
Now that this commit[1] has landed in LLVM the .syso file can be generated for OpenBSD. With the changes to src/runtime running the sample race[2] detects the data race as expected. Based on golang/go#39464 (https://go-review.googlesource.com/c/go/+/237057) from Aaron Bieber <deftly@gmail.com>, however the race_openbsd_amd64.syso file has been built on OpenBSD 6.4 and necessary changes added to race.bash.

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>

2018-06-11runtime/race: implement race detector for ppc64leLynn Boger
This adds the support to enable the race detector for ppc64le. Added runtime/race_ppc64le.s to manage the calls from Go to the LLVM tsan functions, mostly converting from the Go ABI to the PPC64 ABI expected by Clang generated code. Changed racewalk.go to call racefuncenterfp instead of racefuncenter on ppc64le to allow the caller pc to be obtained in the asm code before calling the tsan version. Changed the set up code for racecallbackthunk so it doesn't use the autogenerated save and restore of the link register since that sequence uses registers inconsistent with the normal ppc64 ABI. Made various changes to recognize that race is supported for ppc64le. Ensured that tls_g is updated and accessible from race_linux_ppc64le.s so that the race ctx can be obtained and passed to tsan functions. This enables the race tests for ppc64le in cmd/dist/test.go and increases the timeout when running the benchmarks with the -race option to avoid timing out.

2015-12-29cmd/dist: make test default to --no-rebuildRuss Cox
I'm tired of having to remember it on every command. Rebuilding everything is the wrong default. This CL updates the build script, but the builders may (or may not) need work, depending on whether they rebuild using the test command (I doubt it).

2015-07-11all: link to https instead of httpBrad Fitzpatrick
The one in misc/makerelease/makerelease.go is particularly bad and probably warrants rotating our keys. I didn't update old weekly notes, and reverted some changes involving test code for now, since we're late in the Go 1.5 freeze. Otherwise, the rest are all auto-generated changes, and all manually reviewed.

2015-02-23[dev.cc] cmd/go: fix expansion of 'std', add 'cmd'Russ Cox
The wildcard 'std' is defined in documentation to be all the packages in the Go standard library. It has also historically matched commands in the main repo, but as we implement core commands in Go, that becomes problematic. We need a wildcard that means just the library, and since 'std' is already documented to have that definition, make it so. Add a new wildcard 'cmd' for the commands in the main repo ($GOROOT). Commands that want both can say 'std cmd' (or 'cmd std') to get the effect of the old 'std'. Update make.bash etc to say both std and cmd most of the time. Exception: in race.bash, do not install race-enabled versions of the actual commands. This avoids trying to write binaries while using them, but more importantly it avoids enabling the race detector and its associated memory overhead for the already memory-hungry compilers.
