2014-08-27runtime: fix nacl/386 buildRuss Cox
I changed all the NACL_SYSJMP to NACL_SYSCALL in an earlier CL, but I missed the fact that NACL_SYSCALL will push another return PC on the stack, so that the arguments will no longer be in the right place. Since we have to make our own call, we also have to copy the arguments. Do that. Fixes nacl/386 build. TBR=minux CC=golang-codereviews https://golang.org/cl/135050044

Mutex is consistent with package sync, and when in the unexported Go form it avoids having a conflcit between the type (now mutex) and the function (lock). LGTM=iant R=golang-codereviews, iant CC=dvyukov, golang-codereviews, r https://golang.org/cl/133140043
2014-08-27debug/elf: support arm64 relocationsMichael Hudson-Doyle
This adds the minimal support for AArch64/arm64 relocations needed to get cgo to work (when an isomorphic patch is applied to gccgo) and a test. This change uses the "AAarch64" name for the architecture rather than the more widely accepted "arm64" because that's the name that the relevant docs from ARM such as http://infocenter.arm.com/help/topic/com.arm.doc.ihi0056b/IHI0056B_aaelf64.pdf all use.

2014-08-27runtime: fix nacl buildRuss Cox
The NaCl "system calls" were assumed to have a compatible return convention with the C compiler, and we were using tail jumps to those functions. Don't do that anymore. Correct mistake introduced in newstackcall duringconversion from (SP) to (FP) notation. (Actually this fix, in asm_amd64p32.s, slipped into the C compiler change, but update the name to match what go vet wants.) Correct computation of caller stack pointer in morestack: on amd64p32, the saved PC is the size of a uintreg, not uintptr. This may not matter, since it's been like this for a while, but uintreg is the correct one. (And on non-NaCl they are the same.) This will allow the NaCl build to get much farther. It will probably still not work completely. There's a bug in 6l that needs fixing too. TBR=minux CC=golang-codereviews https://golang.org/cl/134990043

2014-08-27cmd/cc, runtime: preserve C runtime type names in generated GoRuss Cox
uintptr or uint64 in the runtime C were turning into uint in the Go, bool was turning into uint8, and so on. Fix that. Also delete Go wrappers for C functions. The C functions can be called directly now (but still eventually need to be converted to Go).

2014-08-27runtime: give nosplit functions 32 more bytes of headroomRuss Cox
The Go calling convention uses more stack space than C. On 64-bit systems we've been right up against the limit (128 bytes, so only 16 words) and doing awful things to our source code to work around it. Instead of continuing to do awful things, raise the limit to 160 bytes. I am prepared to raise the limit to 192 bytes if necessary, but I think this will be enough. Should fix current link-time stack overflow errors on - nacl/arm - netbsd/amd64 - openbsd/amd64 - solaris/amd64 - windows/amd64 TBR=r CC=golang-codereviews, iant https://golang.org/cl/131450043

2014-08-27cmd/cc, runtime: convert C compilers to use Go calling conventionRuss Cox
To date, the C compilers and Go compilers differed only in how values were returned from functions. This made it difficult to call Go from C or C from Go if return values were involved. It also made assembly called from Go and assembly called from C different. This CL changes the C compiler to use the Go conventions, passing results on the stack, after the arguments. [Exception: this does not apply to C ... functions, because you can't know where on the stack the arguments end.] By doing this, the CL makes it possible to rewrite C functions into Go one at a time, without worrying about which languages call that function or which languages it calls. This CL also updates all the assembly files in package runtime to use the new conventions. Argument references of the form 40(SP) have been rewritten to the form name+10(FP) instead, and there are now Go func prototypes for every assembly function called from C or Go. This means that 'go vet runtime' checks effectively every assembly function, and go vet's output was used to automate the bulk of the conversion. Some functions, like seek and nsec on Plan 9, needed to be rewritten. Many assembly routines called from C were reading arguments incorrectly, using MOVL instead of MOVQ or vice versa, especially on the less used systems like openbsd. These were found by go vet and have been corrected too. If we're lucky, this may reduce flakiness on those systems. Tested on: darwin/386 darwin/amd64 linux/arm linux/386 linux/amd64 If this breaks another system, the bug is almost certainly in the sys_$GOOS_$GOARCH.s file, since the rest of the CL is tested by the combination of the above systems.

2014-08-27runtime: changes to g->atomicstatus (nee status) to support concurrent GCRick Hudson
Every change to g->atomicstatus is now done atomically so that we can ensure that all gs pass through a gc safepoint on demand. This allows the GC to move from one phase to the next safely. In some phases the stack will be scanned. This CL only deals with the infrastructure that allows g->atomicstatus to go from one state to another. Future CLs will deal with scanning and monitoring what phase the GC is in. The major change was to moving to using a Gscan bit to indicate that the status is in a scan state. The only bug fix was in oldstack where I wasn't moving to a Gcopystack state in order to block scanning until the new stack was in place. The proc.go file is waiting for an atomic load instruction.

2014-08-25io: document that Readers and Writers must not retain buffersBrad Fitzpatrick
There are both many callers and many implementations of these interfaces, so make the contract explicit. Callers generally assume this, and at least the standard library and other implementations obey this, but it's never stated explicitly, making it somewhat risky to assume.

2014-08-25cmd/gc, runtime: treat slices and strings like pointers in garbage collectionRuss Cox
Before, a slice with cap=0 or a string with len=0 might have its base pointer pointing beyond the actual slice/string data into the next block. The collector had to ignore slices and strings with cap=0 in order to avoid misinterpreting the base pointer. Now, a slice with cap=0 or a string with len=0 still has a base pointer pointing into the actual slice/string data, no matter what. The collector can now always scan the pointer, which means strings and slices are no longer special. Fixes #8404.
