cmd/internal/sys: mark windows/arm64 as c-shared-capable

2021-06-14T20:36:54+00:00

The platform supports c-shared now, so flip this on. I've given this a
small smoke test using [1], and it was able to pass packets and
generally function well. Since [1] uses quite a bit of Go functionality
under the hood, I think it's a decent test that a lot of things that
should be working are working. So this commit enables it.

cmd/compile: ensure equal functions don't do unaligned loads

2021-05-24T19:06:05+00:00

On architectures which don't support unaligned loads, make sure we
don't generate code that requires them.

Generated hash functions also matter in this respect, but they all look ok.

cmd/dist: refactor test constraints for misc/cgo/testsantizers

2021-03-11T05:38:13+00:00

Currently, the cmd/dist runs test cases in misc/cgo/testsantizers only
when memeory sanitizer is supported, but the tsan tests in
misc/cgo/testsanitizers do not require support for -msan option, which
makes tsan tests can not be run on some unsupported -msan option platforms.

Therefore, this patch moves the test constraints from cmd/dist to
msan_test.go, so that the tsan tests in misc/cgo/testsanitizers
can be run on any system where the C compiler supports -fsanitize=thread
option.

runtime: enable race detector on openbsd/amd64

2021-02-23T12:14:32+00:00

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 , however the race_openbsd_amd64.syso file has
been built on OpenBSD 6.4 and necessary changes added to race.bash.

runtime, cmd: support race detector on darwin/arm64

2020-10-30T19:00:33+00:00

https://reviews.llvm.org/D90435 is the counterpart in LLVM TSAN.

race_linux_arm64.syso is built with LLVM commit
00da38ce2d36c07f12c287dc515d37bb7bc410e9 on a macOS/ARM64 machine.
(It is not built on a builder with golang.org/x/build/cmd/racebuild
as we don't have darwin/arm64 builder for now.)

Updates #38485.

Revert "cmd/compile,cmd/internal/sys: enable additional build modes on linux/riscv64"

2020-10-29T18:26:18+00:00

This reverts CL 263457.

It turns out that this still missed changes to cmd/link/internal/ld/config.go
and some of these build modes also fail once cgo is enabled. Disable again for
now.

With previous CLs, internal linking without cgo should work well.
Enable it by default. And stop always requiring cgo.

Enable tests that were previously disabled due to the lack of
internal linking.

all: add GOOS=ios GOARCH=amd64 target for the ios simulator

2020-10-22T17:13:24+00:00

The Go toolchain has supported the simulator for years, but always in
buildmode=c-archive which is intrinsically externally linked and PIE.

This CL moves that support from GOOS=darwin GOARCH=amd64 -tags=ios to
just GOOS=ios GOARCH=amd64 to match the change for iOS devices.

This change also forces external linking and defaults to buildmode=pie
to support Go binaries in the default buildmode to run on the simulator.

CL 255257 added the necessary support to the exec wrapper.

Fixes #42100
