* runtime: don't acquirem on malloc fast pathDmitriy Vyukov2014-08-181-1/+4
| | | | | | | | | | | | | | | | | | | Mallocgc must be atomic wrt GC, but for performance reasons don't acquirem/releasem on fast path. The code does not have split stack checks, so it can't be preempted by GC. Functions like roundup/add are inlined. And onM/racemalloc are nosplit. Also add debug code that checks these assumptions. benchmark old ns/op new ns/op delta BenchmarkMalloc8 20.5 17.2 -16.10% BenchmarkMalloc16 29.5 27.0 -8.47% BenchmarkMallocTypeInfo8 31.5 27.6 -12.38% BenchmarkMallocTypeInfo16 34.7 30.9 -10.95% LGTM=khr R=golang-codereviews, khr CC=golang-codereviews, rlh, rsc https://golang.org/cl/123100043

* runtime: rewrite malloc in Go.Keith Randall2014-07-301-1/+1
| | | | | | | | | | | | | This change introduces gomallocgc, a Go clone of mallocgc. Only a few uses have been moved over, so there are still lots of uses from C. Many of these C uses will be moved over to Go (e.g. in slice.goc), but probably not all. What should remain of C's mallocgc is an open question.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's a bit slower, but not painfully so.

* cmd/api: fix tool for recent go/build changeRuss Cox2013-09-111-0/+4
| | | | | | | | | | | | | | | | | | Asking about runtime/cgo when CgoEnabled=false now correctly returns an error from build.Import (specifically, NoGoError), because there are no buildable Go files in that directory. The API tool was depending on it returning a package with no Go files instead. Correct that assumption. Fixes all.bash on local machines. (Dashboard appears not to be running the api tool at all.)

Old: $ go version go version devel New: $ go version go version devel +0a3866d6cc6b Mon Sep 24 20:08:05 2012 -0400 The date and time (and time zone) is that of the most recent commit, not the time of the build itself. With some effort we could normalize the zone, but I don't think it's worth the effort (more C coding, since Mercurial is unhelpful). R=r, dsymonds CC=golang-dev https://golang.org/cl/6569049

* api: add Linux/ARM to go1 APIShenghou Ma2012-06-041-0/+1
| | | | | | | | | | | It's very unfortunate that the type of Data field of struct RawSockaddr is [14]uint8 on Linux/ARM instead of [14]int8 on all the others. btw, it should be [14]int8 according to my header files. R=golang-dev, bradfitz CC=golang-dev https://golang.org/cl/6275050
* api: add FreeBSD to go1 APIBrad Fitzpatrick2012-06-011-0/+2
| | | | | | | | | | | | | | Now that gri has made go/parser 15% faster, I offer this change to slow back down cmd/api ~proportionately, adding FreeBSD to the go1-checked set of platforms. Really we should have done this earlier. This will prevent us from breaking FreeBSD compatibility accidentally in the future. R=golang-dev, r CC=golang-dev https://golang.org/cl/6279044
* cmd/api: add flag to specify contextsBrad Fitzpatrick2012-05-231-6/+36
| | | | | | | | | I needed this to explore per-GOOS/GOARCH differences in pkg syscall for a recent CL. Others may find it useful too. R=golang-dev, rsc CC=golang-dev https://golang.org/cl/6236046
* cmd/api: add api/next.txtBrad Fitzpatrick2012-05-221-33/+74
| | | | | | | | | | | | | | | | This quiets all.bash noise for upcoming features we know about. The all.bash warnings will now only print for things not in next.txt (or in next.txt but not in the API). Once an API is frozen, we rename next.txt to a new frozen file (like go1.txt) Fixes #3651 R=golang-dev, r CC=golang-dev https://golang.org/cl/6218069

* build: catch API changes during buildBrad Fitzpatrick2012-03-171-2/+11
| | | | | | | | | | | | Adds new file api/go1.txt, locking down the current API. Any changes to the API will need to update that file. run.bash (but not make.bash, or Windows) will check for accidental API changes. R=golang-dev, dsymonds, rsc CC=golang-dev https://golang.org/cl/5820070

* cmd/api: set compiler for all build contexts.David Symonds2012-03-121-0/+6
| | | | | | | | | | | The generated syscall files for Windows are still breaking "go tool api" (unknown function []byte); I'll look at fixing that separately. Fixes #3285. R=bradfitz CC=golang-dev https://golang.org/cl/5777062
* go/build: replace FindTree, ScanDir, Tree, DirInfo with Import, PackageRuss Cox2012-03-011-15/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an API change, but one I have been promising would happen when it was clear what the go command needed. This is basically a complete replacement of what used to be here. build.Tree is gone. build.DirInfo is expanded and now called build.Package. build.FindTree is now build.Import(package, srcDir, build.FindOnly). The returned *Package contains information that FindTree returned, but applicable only to a single package. build.ScanDir is now build.ImportDir. build.FindTree+build.ScanDir is now build.Import. The new Import API allows specifying the source directory, in order to resolve local imports (import "./foo") and also allows scanning of packages outside of $GOPATH. They will come back with less information in the Package, but they will still work. The old go/build API exposed both too much and too little. This API is much closer to what the go command needs, and it works well enough in the other places where it is used. Path is gone, so it can no longer be misused. (Fixes issue 2749.) This CL updates clients of go/build other than the go command. The go command changes are in a separate CL, to be submitted at the same time.
