* runtime: implement cheaper context switch on Linux/AMD64Ian Lance Taylor2019-05-311-0/+20
| | | | | | | | | | | | | | | | | Currently, goroutine switches are implemented with libc getcontext/setcontext functions, which saves/restores the machine register states and also the signal context. This does more than what we need, and performs an expensive syscall. This CL implements a simplified version of getcontext/setcontext, in assembly, that only saves/restores the necessary part, i.e. the callee-save registers, and the PC, SP. A simplified version of makecontext, written in C, is also added. Currently this is only implemented on Linux/AMD64.

* libgo: don't provide ustat on arm64 GNU/LinuxIan Lance Taylor2015-09-151-27/+47
| | | | | | | | | | | This avoids linker warnings when linking against glibc, as apparently arm64 GNU/Linux does not support the ustat system call. Also update to automake 1.11.6, as that is the new GCC standard. Reviewed-on: https://go-review.googlesource.com/14567 From-SVN: r227777
