2021-10-28all: go fix -fix=buildtag std cmd (except for bootstrap deps, vendor)Russ Cox
When these packages are released as part of Go 1.18, Go 1.16 will no longer be supported, so we can remove the +build tags in these files. Ran go fix -fix=buildtag std cmd and then reverted the bootstrapDirs as defined in src/cmd/dist/buildtool.go, which need to continue to build with Go 1.4 for now. Also reverted src/vendor and src/cmd/vendor, which will need to be updated in their own repos first. Manual changes in runtime/pprof/mprof_test.go to adjust line numbers. For #41184.

2021-10-26syscall: add utimensat libc wrapper on darwinTobias Klauser
Add utimensat as a wrapper around the libc function of the same name. utimensat was added in macOS 10.13 which is the minimum supported release since Go 1.17 dropped support for macOS 10.12. This also allows to drop the fallback to setattrlistTimes which was used to set timestamps with nanosecond resolution before utimensat could be used, see #22528 and CL 74952.

Directly wrap the getcwd implementation provided by libSystem.dylib on darwin and use it to implement Getwd like on the BSDs.

2020-09-23all: add GOOS=iosCherry Zhang
Introduce GOOS=ios for iOS systems. GOOS=ios matches "darwin" build tag, like GOOS=android matches "linux" and GOOS=illumos matches "solaris". Only ios/arm64 is supported (ios/amd64 is not). GOOS=ios and GOOS=darwin remain essentially the same at this point. They will diverge at later time, to differentiate macOS and iOS. Uses of GOOS=="darwin" are changed to (GOOS=="darwin" || GOOS=="ios"), except if it clearly means macOS (e.g. GOOS=="darwin" && GOARCH=="amd64"), it remains GOOS=="darwin". Updates #38485.

2017-11-01syscall: use setattrlist for UtimesNano on Darwin for ns resolutionEvan Jones
Mac OS X 10.13 introduced APFS which stores nanosecond resolution timestamps. The implementation of os.Stat already returns full resolution timestamps, but os.Chtimes only sets timestamps with microsecond resolution. Fix this by using setattrlist on Darwin, which takes a struct timeval with nanosecond resolution. This is what Mac OS X 10.13 appears uses to implement utimensat, according to dtruss.

2017-08-14syscall: add utimensat and use it for UtimesNano on BSD and SolarisTobias Klauser
All the BSDs and Solaris support the utimensat syscall, but Darwin doesn't. Account for that by adding the //sys lines not to syscall_bsd.go but the individual OS's syscall_*.go files and implement utimensat on Darwin as just returning ENOSYS, such that UtimesNano will fall back to use utimes as it currently does unconditionally. This also adds the previously missing utimensat syscall number for FreeBSD and Dragonfly.
