2021-02-19runtime: convert windows/arm64 assemblyRuss Cox
The assembly is mostly a straightforward conversion of the equivalent arm assembly. This CL is part of a stack adding windows/arm64 support (#36439), intended to land in the Go 1.17 cycle.

2021-01-21runtime: switch openbsd/arm64 to pthreadsJoel Sing
This switches openbsd/arm64 to thread creation via pthreads, rather than doing direct system calls.

Minor optimization. Spotted while working on that code.

2020-10-28runtime: save/restore g unconditionally on darwin/arm64Cherry Zhang
Now that we always have TLS set up, we can always save the G register, regardless of whether cgo is used. This makes pure Go programs signal-safe. Updates #38485.

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.

2019-04-08runtime,runtime/cgo: set up TLS storage for Android Q without cgoElias Naur
Android Q frees a static TLS slot for us to use. Use the offset of that slot as the default for our TLS offset. As a result, runtime/cgo is no more a requirement for Android Q and newer.
