* all: power64 is now ppc64Russ Cox2014-12-052-6/+6

* [dev.cc] 9a: make RET a synonym for RETURN; use "g" instead of "R30"Austin Clements2014-11-181-1/+2
| | | | | | | | | | | | | | | | Previously, 9a was the only assembler that had a different name for RET, causing unnecessary friction in simple files that otherwise assembled on all architectures. Add RET so these work on 9a. This also renames "R30" to "g" to avoid unintentionally clobbering g in assembly code. This parallels a change made to 5a.

* [dev.power64] cmd/5a, cmd/6a, cmd/8a, cmd/9a: make labels function-scopedRuss Cox2014-10-284-1540/+1137
| | | | | | | | | | | | | | | | | | | | | | I removed support for jumping between functions years ago, as part of doing the instruction layout for each function separately. Given that, it makes sense to treat labels as function-scoped. This lets each function have its own 'loop' label, for example. Makes the assembly much cleaner and removes the last reason anyone would reach for the 123(PC) form instead. Note that this is on the dev.power64 branch, but it changes all the assemblers. The change will ship in Go 1.5 (perhaps after being ported into the new assembler). Came up as part of CL 167730043.

* [dev.power64] 9a: correct generation of four argument opsAustin Clements2014-10-281-3/+2
| | | | | | | | | | | | | | The "to" field was the penultimate argument to outgcode, instead of the last argument, which swapped the third and fourth operands. The argument order was correct in a.y, so just swap the meaning of the arguments in outgcode. This hadn't come up because we hadn't used these more obscure operations in any hand-written assembly until now.

* [dev.power64] all: merge default into dev.power64Austin Clements2014-10-221-0/+1
| | | | | | | | | | | This brings dev.power64 up-to-date with the current tip of default. go_bootstrap is still panicking with a bad defer when initializing the runtime (even on amd64). LGTM=rsc R=rsc CC=golang-codereviews https://codereview.appspot.com/152570049
* build: merge the great pkg/ rename into dev.power64Austin Clements2014-10-222-2/+2
| | | | | | | | | This also removes pkg/runtime/traceback_lr.c, which was ported to Go in an earlier commit and then moved to runtime/traceback.go. Reviewer: rsc@golang.org rsc: LGTM
* [dev.power64] cmd/9a: use new flag parserRuss Cox2014-08-121-64/+65
| | | | | | | | | | | | Copy main from 6a. Fixes various things, but the main thing is the use of the new flag parser. The go command expects to be able to use -trimpath and not have it be interpreted as -t rimpath. LGTM=minux R=minux CC=golang-codereviews https://codereview.appspot.com/126100043
* [dev.power64] cmd/9a: use liblink, add required additional instructions.Shenghou Ma2014-08-077-439/+4234

* [dev.power64] cmd/9a, cmd/9c, cmd/9l, liblink: import code from Vita Nuova.Shenghou Ma2014-08-063-0/+2110
No modifications other than adding copyright header to each file, and concatenating several cmd/9l files together to form the liblink files. LGTM=rsc R=rsc, iant CC=golang-codereviews https://codereview.appspot.com/123840043
