2020-12-09	all: update to use os.ReadFile, os.WriteFile, os.CreateTemp, os.MkdirTemp	Russ Cox
	As part of #42026, these helpers from io/ioutil were moved to os. (ioutil.TempFile and TempDir became os.CreateTemp and MkdirTemp.) Update the Go tree to use the preferred names. As usual, code compiled with the Go 1.4 bootstrap toolchain and code vendored from other sources is excluded. ReadDir changes are in a separate CL, because they are not a simple search and replace. For #42026.

2018-03-07	runtime: get traceback from VDSO code	Ian Lance Taylor
	Currently if a profiling signal arrives while executing within a VDSO the profiler will report _ExternalCode, which is needlessly confusing for a pure Go program. Change the VDSO calling code to record the caller's PC/SP, so that we can do a traceback from that point. If that fails for some reason, report _VDSO rather than _ExternalCode, which should at least point in the right direction. This adds some instructions to the code that calls the VDSO, but the slowdown is reasonably negligible: name old time/op new time/op delta ClockVDSOAndFallbackPaths/vDSO-8 40.5ns ± 2% 41.3ns ± 1% +1.85% (p=0.002 n=10+10) ClockVDSOAndFallbackPaths/Fallback-8 41.9ns ± 1% 43.5ns ± 1% +3.84% (p=0.000 n=9+9) TimeNow-8 41.5ns ± 3% 41.5ns ± 2% ~ (p=0.723 n=10+10) Fixes #24142 Change-Id: Iacd935db3c4c782150b3809aaa675a71799b1c9c Reviewed-on: https://go-review.googlesource.com/97315 Run-TryBot: Ian Lance Taylor <iant@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Austin Clements <austin@google.com>
