8 daysinternal/syscall/unix: properly support AT_SYMLINK_NOFOLLOW on LinuxDamien Neil
On Linux, the fchmodat syscall silently ignores the AT_SYMLINK_NOFOLLOW flag. Change the Linux Fchmodat function to use the fstatat2 syscall (added in Linux 6.6) when available. When fstatat2 is not available, use the same workaround as GNU libc and musl, which is to open the target file with O_PATH and then chmod it via /proc/self/fd. This change fixes an os.Root escape, where Root.Chmod could follow a symlink and act on a file outside of the root. Root.Chmod checks to see if its target is a symlink before calling fchmodat, so this escape requires the target to be replaced with a symlink in between the initial check and the fchmodat. Thanks to Uuganbayar Lkhamsuren (https://github.com/uug4na) for reporting this issue.

2025-10-09cmd/compile: call generated size-specialized malloc functions directlyMichael Matloob
This change creates calls to size-specialized malloc functions instead of calls to newObject when we know the size of the allocation at compilation time. Most of it is a matter of calling the newObject function (which will create calls to the size-specialized functions) rather then the newObjectNonSpecialized function (which won't). In the newHeapaddr, small, non-pointer case, we'll create a non specialized newObject and transform that into the appropriate size-specialized function when we produce the mallocgc in flushPendingHeapAllocations. We have to update some of the rewrites in generic.rules to also apply to the size-specialized functions when they apply to newObject. The messiest thing is we have to adjust the offset we use to save the memory profiler stack, because the depth of the call to profilealloc is two frames fewer in the size-specialized malloc functions compared to when newObject calls mallocgc. A bunch of tests have been adjusted to account for that.

2025-09-09cmd/cgo: run gcc to get errors and debug info in parallelmatloob
This change kicks off the work to load the debug info when processing each file, and then waits for all the files to be processed before starting the single-goroutined part that processes them. The processing is very order dependent so we won't try to make it concurrent. Though in a later CL we can wait for only the relevant package to have been processed concurrently before doing the single-goroutined processing for it instead of waiting for all packages to be processed concurrently before the single goroutine section. We use a par.Queue to make sure we're not running too many gcc compiles at the same time. The change to cmd/dist makes the par package available to cgo.

2024-08-22cmd/dist: set go version in bootstrap go.mod fileMichael Matloob
The commands to build the bootstrap toolchains and go commands are run from modules created by two bootstrap go.mod files: one is used when building toolchain1 and go_bootstrap, and the other is used for toolchain2 and toolchain3, and the final build. Currently the first has a go directive specifying go 1.20, and the second one does not have a go directive at all. This affects the default GODEBUG setting when building the final toolchain: the default GODEBUG value is based on the go version of the go.mod file, and when the go.mod file does not have a version it defaults to go1.16. We should set the go directive on the bootstrap used for the second half of the builds to use the current go verison from the std's go.mod file (which is the same as the version on cmd's go.mod file). The go.mod file used for the initial bootstrap should have a go directive with the minimum version of the toolchain required for bootstrapping. That version is the current version - 2 rounded down to an even number.

2024-04-18cmd/dist: allow arbitrary package renames for bootstrap importsMichael Pratt
Import declaration matching currently has a list of specific cases. It allows bare imports, dot imports, and renamed imports named "exec" and "rtabi". Keeping a specific allowlist of renamed imports is unnecessary and causes annoyance for developers adding such imports, as the bootstrap build errors do not make it clear that this is where the issue lies. We can simplify this to be much more general. The body of the condition will still only rewrite imports in cmd/ or in bootstrapDirs. I believe the only downside of this change is that it makes it a bit more likely to match and replace within comments. That said, there should be no harm in replacements within comments. This change results in no change to the resulting bootstrap source tree: $ diff -u -r /tmp/bootstrap.before/src /tmp/bootstrap.after/src diff -u -r /tmp/bootstrap.before/src/bootstrap/internal/buildcfg/zbootstrap.go /tmp/bootstrap.after/src/bootstrap/internal/buildcfg/zbootstrap.go --- /tmp/bootstrap.before/src/bootstrap/internal/buildcfg/zbootstrap.go 2024-03-27 12:29:27.439540946 -0400 +++ /tmp/bootstrap.after/src/bootstrap/internal/buildcfg/zbootstrap.go 2024-03-27 12:28:08.516211238 -0400 @@ -20,6 +20,6 @@ const defaultGOEXPERIMENT = `` const defaultGO_EXTLINK_ENABLED = `` const defaultGO_LDSO = `` -const version = `devel go1.23-38087c80ae Wed Mar 27 12:09:16 2024 -0400` +const version = `devel go1.23-fa64f04409 Wed Mar 27 12:22:52 2024 -0400` const defaultGOOS = runtime.GOOS const defaultGOARCH = runtime.GOARCH Change-Id: Ia933c6373f366f2e607b28d900227c24cb214674 Reviewed-on: https://go-review.googlesource.com/c/go/+/574735 Reviewed-by: Cherry Mui <cherryyz@google.com> LUCI-TryBot-Result: Go LUCI <golang-scoped@luci-project-accounts.iam.gserviceaccount.com> Auto-Submit: Michael Pratt <mpratt@google.com>

Now cmd/preprofile and cmd/compile run the same code for initial processing of a pprof profile, guaranteeing that they always stay in sync.

2023-04-20cmd/dist: refactor generated cgo-support logicBryan C. Mills
During bootstrapping, cmd/dist writes a file indicating which GOOS/GOARCH combinations are valid, and which support cgo-enabled builds. That information previously went into the go/build package, but today it fits in more naturally in the internal/platform package (which already has a number of functions indicating feature support for GOOS/GOARCH combinations). Moreover, as of CL 450739 the cmd/go logic for determining whether to use cgo is somewhat more nuanced than the go/build logic: cmd/go checks for the presence of a C compiler, whereas go/build does not (mostly because it determines its configuration at package-init time, and checking $PATH for a C compiler is somewhat expensive). To simplify this situation, this change: - consolidates the “cgo supported” check in internal/platform (alongside many other platform-support checks) instead of making it a one-off in go/build, - and updates a couple of tests to use testenv.HasCGO instead of build.Default.CgoEnabled to decide whether to test a cgo-specific behavior. For #58884. For #59500.

2022-10-05cmd/compile: add late lower pass for last rules to runeric fang
Usually optimization rules have corresponding priorities, some need to be run first, some run next, and some run last, which produces the best code. But currently our optimization rules have no priority, this CL adds a late lower pass that runs those rules that need to be run at last, such as split unreasonable constant folding. This pass can be seen as the second round of the lower pass. For example: func foo(a, b uint64) uint64 { d := a+0x1234568 d1 := b+0x1234568 return d&d1 } The code generated by the master branch: 0x0004 00004 ADD $19088744, R0, R2 // movz+movk+add 0x0010 00016 ADD $19088744, R1, R1 // movz+movk+add 0x001c 00028 AND R1, R2, R0 This is because the current constant folding optimization rules do not take into account the range of constants, causing the constant to be loaded repeatedly. This CL splits these unreasonable constants folding in the late lower pass. With this CL the generated code: 0x0004 00004 MOVD $19088744, R2 // movz+movk 0x000c 00012 ADD R0, R2, R3 0x0010 00016 ADD R1, R2, R1 0x0014 00020 AND R1, R3, R0 This CL also adds constant folding optimization for ADDS instruction. In addition, in order not to introduce the codegen regression, an optimization rule is added to change the addition of a negative number into a subtraction of a positive number. go1 benchmarks: name old time/op new time/op delta BinaryTree17-8 1.22s ± 1% 1.24s ± 0% +1.56% (p=0.008 n=5+5) Fannkuch11-8 1.54s ± 0% 1.53s ± 0% -0.69% (p=0.016 n=4+5) FmtFprintfEmpty-8 14.1ns ± 0% 14.1ns ± 0% ~ (p=0.079 n=4+5) FmtFprintfString-8 26.0ns ± 0% 26.1ns ± 0% +0.23% (p=0.008 n=5+5) FmtFprintfInt-8 32.3ns ± 0% 32.9ns ± 1% +1.72% (p=0.008 n=5+5) FmtFprintfIntInt-8 54.5ns ± 0% 55.5ns ± 0% +1.83% (p=0.008 n=5+5) FmtFprintfPrefixedInt-8 61.5ns ± 0% 62.0ns ± 0% +0.93% (p=0.008 n=5+5) FmtFprintfFloat-8 72.0ns ± 0% 73.6ns ± 0% +2.24% (p=0.008 n=5+5) FmtManyArgs-8 221ns ± 0% 224ns ± 0% +1.22% (p=0.008 n=5+5) GobDecode-8 1.91ms ± 0% 1.93ms ± 0% +0.98% (p=0.008 n=5+5) GobEncode-8 1.40ms ± 1% 1.39ms ± 0% -0.79% (p=0.032 n=5+5) Gzip-8 115ms ± 0% 117ms ± 1% +1.17% (p=0.008 n=5+5) Gunzip-8 19.4ms ± 1% 19.3ms ± 0% -0.71% (p=0.016 n=5+4) HTTPClientServer-8 27.0µs ± 0% 27.3µs ± 0% +0.80% (p=0.008 n=5+5) JSONEncode-8 3.36ms ± 1% 3.33ms ± 0% ~ (p=0.056 n=5+5) JSONDecode-8 17.5ms ± 2% 17.8ms ± 0% +1.71% (p=0.016 n=5+4) Mandelbrot200-8 2.29ms ± 0% 2.29ms ± 0% ~ (p=0.151 n=5+5) GoParse-8 1.35ms ± 1% 1.36ms ± 1% ~ (p=0.056 n=5+5) RegexpMatchEasy0_32-8 24.5ns ± 0% 24.5ns ± 0% ~ (p=0.444 n=4+5) RegexpMatchEasy0_1K-8 131ns ±11% 118ns ± 6% ~ (p=0.056 n=5+5) RegexpMatchEasy1_32-8 22.9ns ± 0% 22.9ns ± 0% ~ (p=0.905 n=4+5) RegexpMatchEasy1_1K-8 126ns ± 0% 127ns ± 0% ~ (p=0.063 n=4+5) RegexpMatchMedium_32-8 486ns ± 5% 483ns ± 0% ~ (p=0.381 n=5+4) RegexpMatchMedium_1K-8 15.4µs ± 1% 15.5µs ± 0% ~ (p=0.151 n=5+5) RegexpMatchHard_32-8 687ns ± 0% 686ns ± 0% ~ (p=0.103 n=5+5) RegexpMatchHard_1K-8 20.7µs ± 0% 20.7µs ± 1% ~ (p=0.151 n=5+5) Revcomp-8 175ms ± 2% 176ms ± 3% ~ (p=1.000 n=5+5) Template-8 20.4ms ± 6% 20.1ms ± 2% ~ (p=0.151 n=5+5) TimeParse-8 112ns ± 0% 113ns ± 0% +0.97% (p=0.016 n=5+4) TimeFormat-8 156ns ± 0% 145ns ± 0% -7.14% (p=0.029 n=4+4) Change-Id: I3ced26e89041f873ac989586514ccc5ee09f13da Reviewed-on: https://go-review.googlesource.com/c/go/+/425134 Reviewed-by: Keith Randall <khr@google.com> Reviewed-by: Cherry Mui <cherryyz@google.com> TryBot-Result: Gopher Robot <gobot@golang.org> Reviewed-by: Keith Randall <khr@golang.org> Run-TryBot: Eric Fang <eric.fang@arm.com>
2022-10-04cmd/internal/sys: migrate support.go functions to new internal pkgThan McIntosh
Separate out the functions from cmd/internal/sys/support.go and migrate them to a new package internal/platform, so that functions such as "RaceDetectorSupported" can be called from tests in std as well as in cmd. This isn't a complete move of everything in cmd/internal/sys; there are still many functions left. The original version of this CL (patch set 1) called the new package "internal/sys", but for packages that needed both "internal/sys" and "cmd/internal/sys" the import of the former had to be done with a different name, which was confusing and also required a hack in cmd/dist. Updates #56006.

2022-09-27cmd/compile: add coverage fixup modeThan McIntosh
Adds a -coveragecfg=<configfile> command line option to the compiler to help support a cooperative "tool and compiler" mode for coverage instrumentation. In this mode the cmd/cover tool generates most of the counter instrumentation via source-to-source rewriting, but the compiler fixes up the result if passed the "-coveragecfg" option. The fixups include: - reclassifying counter variables (special storage class) - marking meta-data variables are read-only - adding in an init call to do registation Updates #51430.
