* cmd/internal/objabi: extract shared functionality from objMatthew Dempsky2017-04-191-21/+0
| | | | | | | | | | | | | | | | | | | | | | | Now only cmd/asm and cmd/compile depend on cmd/internal/obj. Changing the assembler backends no longer requires reinstalling cmd/link or cmd/addr2line. There's also now one canonical definition of the object file format in cmd/internal/objabi/doc.go, with a warning to update all three implementations. objabi is still something of a grab bag of unrelated code (e.g., flag and environment variable handling probably belong in a separate "tool" package), but this is still progress. Fixes #15165. Fixes #20026.

* cmd/compile: ppc64le working, not optimized enoughDavid Chase2016-08-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | This time with the cherry-pick from the proper patch of the old CL. Stack size increased. Corrected NaN-comparison glitches. Marked g register as clobbered by calls. Fixed shared libraries. live_ssa.go still disabled because of differences. Presumably turning on more optimization will fix both the stack size and the live_ssa.go glitches. Enhanced debugging output for shared libs test. Rebased onto master. Updates #16010.

* all: make copyright headers consistent with one space after periodBrad Fitzpatrick2016-03-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | This is a subset of https://golang.org/cl/20022 with only the copyright header lines, so the next CL will be smaller and more reviewable. Go policy has been single space after periods in comments for some time. The copyright header template at: https://golang.org/doc/contribute.html#copyright also uses a single space. Make them all consistent.

* cmd/internal/obj: remove 3 incorrect copyright noticesRuss Cox2015-12-141-30/+0
| | | | | | | | | | | | | | | These three files contain only code written for Go (and trivial amounts at that), not any code ported from Inferno or Plan 9. Remove the incorrect Inferno/Plan 9 notices. Fixes #13576.

* cmd/internal/obj, cmd/link, runtime: increase stack limit to accommodate ↵Michael Hudson-Doyle2015-11-121-1/+1
| | | | | | | | | | | | | | larger frames on ppc64x Larger stack frames mean nosplit functions use more stack and so the limit needs to increase. The change to test/nosplit.go is a bit ugly but I can't really think of a way to make it nicer.

* [dev.cc] cmd/internal/obj: convert liblink C to GoRuss Cox2015-01-211-0/+52
This CL adds the real cmd/internal/obj packages. Collectively they correspond to the liblink library. The conversion was done using rsc.io/c2go's run script at rsc.io/c2go repo version 706fac7. This is not the final conversion, just the first working draft. There will be more updates, but this works well enough to use with go tool objwriter and pass all.bash.
