* runtime: break out system-specific constants into package sysMichael Matloob2015-11-121-2/+5
| | | | | | | | | | | runtime/internal/sys will hold system-, architecture- and config- specific constants. Updates #11647 Change-Id: I6db29c312556087a42e8d2bdd9af40d157c56b54 Reviewed-on: https://go-review.googlesource.com/16817 Reviewed-by: Russ Cox <rsc@golang.org>
* runtime: run on GOARM=5 and GOARM=6 uniprocessor freebsd/arm systemsRuss Cox2015-08-071-1/+0
| | | | | | | | | | | | | | | | | | | | Also, crash early on non-Linux SMP ARM systems when GOARM < 7; without the proper synchronization, SMP cannot work. Linux is okay because we call kernel-provided routines for synchronization and barriers, and the kernel takes care of providing the right routines for the current system. On non-Linux systems we are left to fend for ourselves. It is possible to use different synchronization on GOARM=6, but it's too late to do that in the Go 1.5 cycle. We don't believe there are any non-Linux SMP GOARM=6 systems anyway. Fixes #12067.

* runtime: mark all runtime.cputicks implementations NOSPLITDave Cheney2015-04-151-0/+1
| | | | | | | | | | | | Fixes #10450 runtime.cputicks is called from runtime.exitsyscall and must not split the stack. cputicks is implemented in several ways and the NOSPLIT annotation was missing from a few of these.

| | | | | | | | | | | It's rather unsporting of the kernel to give us a pointer to unaligned memory. This fixes one crash, the next crash occurs in the soft float emulation. LGTM=minux, rsc, austin R=minux, rsc, austin CC=golang-codereviews https://golang.org/cl/177730043

The conversion was done with an automated tool and then modified only as necessary to make it compile and run. [This CL is part of the removal of C code from package runtime. See golang.org/s/dev.cc for an overview.] LGTM=r R=r CC=austin, dvyukov, golang-codereviews, iant, khr https://golang.org/cl/174830044
