* libbio, all cmd: consistently use BGETC/BPUTC instead of Bgetc/BputcDmitriy Vyukov2013-08-301-2/+24
| | | | | | | | | | | | | | | | | | | Also introduce BGET2/4, BPUT2/4 as they are widely used. Slightly improve BGETC/BPUTC implementation. This gives ~5% CPU time improvement on go install -a -p1 std.

* build: add intptr typedef for Plan 9Anthony Martin2013-06-043-24/+27
| | | | | | | | | | | | | | | | | | | | | | Revision 01810e5c68e9 added the following to src/pkg/runtime/stack.h: StackPreempt = (uintptr)(intptr)0xffffade, The typedef for intptr is defined in two places: 1. src/pkg/runtime/runtime.h for use by the runtime 2. include/u.h for use by the compilers and linkers On Plan 9, we don't use include/u.h but instead augment the host's u.h with extra typedefs. These are in include/plan9/GOARCH/u.h. We forgot to add intptr. It didn't cause a problem until now since that typedef was never used outside the runtime.

| | | | | | | | | | | | Change build system to set GO_EXTLINK_ENABLED=0 by default for OS X 10.6, since the system linker has a bug and can not handle the object files generated by 6l. Fixes issue 5130. R=golang-dev, r CC=golang-dev https://codereview.appspot.com/8183043

* build: clang supportRuss Cox2013-02-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | This works with at least one version of clang that existed at one moment in time. No guarantees about clangs past or future. To try: CC=clang all.bash It does not work with the Xcode clang, because that clang fails at printing a useful answer to: clang -print-libgcc-file-name The clang that works prints a full path name for that command, not just "libgcc.a". Fixes issue 4713. R=iant, minux.ma CC=golang-dev https://codereview.appspot.com/7323068
* include: Plan 9: hide any previous definition of RunemaxAkshat Kumar2013-01-301-0/+2
| | | | | | | | | | | | | Runemax is already defined in libc on 64-bit version of Plan 9, but is not defined on other versions. To accommodate, we make sure to rename any previous instance of Runemax and re-define it subsequently.

* cmd/5l, cmd/6l, cmd/8l, cmd/cc, cmd/gc: new flag parsingRuss Cox2013-01-061-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This CL adds a flag parser that matches the semantics of Go's package flag. It also changes the linkers and compilers to use the new flag parser. Command lines that used to work, like 8c -FVw 6c -Dfoo 5g -I/foo/bar now need to be split into separate arguments: 8c -F -V -w 6c -D foo 5g -I /foo/bar The new spacing will work with both old and new tools. The new parser also allows = for arguments, as in 6c -D=foo 5g -I=/foo/bar but that syntax will not work with the old tools. In addition to matching standard Go binary flag parsing, the new flag parser generates more detailed usage messages and opens the door to long flag names. The recently added gc flag -= has been renamed -complete. R=remyoudompheng, daniel.morsing, minux.ma, iant CC=golang-dev https://codereview.appspot.com/7035043
* cmd/dist, cmd/8g: implement GO386=387/sse to choose FPU flavour.R?my Oudompheng2013-01-021-0/+1
| | | | | | | | | | | | | | | A new environment variable GO386 is introduced to choose between code generation targeting 387 or SSE2. No auto-detection is performed and the setting defaults to 387 to preserve previous behaviour. The patch is a reorganization of CL6549052 by rsc. Fixes issue 3912.

* build: add include files for Plan 9Anthony Martin2012-01-316-0/+55
| | | | | | | | | | | | | | | | | Previously, I had made available a tarball of the modified system headers that were necessary to build on Plan 9 but that was only a stopgap. I think this method is much better since no files outside of $GOROOT will have to be added or modified during the build process. Also, this is just the first step. I'll change the build to reference these files in another CL (that also contains a few more Makefile changes). R=golang-dev, rsc CC=golang-dev http://codereview.appspot.com/5552056

* gopack: change archive file name length back to 16Russ Cox2011-11-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | This CL grew the archive file name length from 16 to 64: changeset: 909:58574851d792 user: Russ Cox <rsc@golang.org> date: Mon Oct 20 13:53:56 2008 -0700 Back then, every x.go file in a package became an x.6 file in the archive. It was important to be able to allow the use of long Go source file names, hence the increase in size. Today, all Go source files compile into a single _go_.6 file regardless of their names, so the archive file name length no longer needs to be long. The longer name causes some problems on Plan 9, where the native archive format is the same but with 16-byte names, so revert back to 16.

* build: define getcallerpc in u.h (fix for Plan 9 build)Lucio De Re2011-07-251-0/+2
| | | | | | | | | | | | | | . By defining getcallerpc(x) as __builtin_return_address(0) here, it becomes possible to use the Plan 9 compatible form when compiling using GCC. The alternative is to add conditional compilation based on the compiler identity in "cmd/8g/gsubr.c" to distinguish between the two cases.

* build: fix header files for Plan 9Lucio De Re2011-06-141-0/+1
| | | | | | | | | | | | | | | | | | | The "elf.h" header changes involve only comments, the released Plan 9 C preprocessing function does not cope with multiline comments following the #define keyword. All multiline comments have been moved to the line above the associated definition. Sigh! Fixing the Plan 9 compiler is not an option. <time.h> does not exist in the Plan 9 Native library. I have moved it from src/cmd/ld/pe.h to include/u.h. RSC correctly points out that this copy of <u.h> is not the one used to compile the Go release on Plan 9 platforms.
