The Go programming language
fd2bc95d53
[This CL is part of the removal of C code from package runtime. See golang.org/s/dev.cc for an overview.] export.c, lex.c: Add -asmhdr flag to write assembly header file with struct field offsets and const values. cmd/dist used to construct this file by interpreting output from the C compiler. Generate it from the Go definitions instead. Also, generate the form we need directly, instead of relying on cmd/dist for reprocessing. lex.c, obj.c: If the C compiler accepted #pragma cgo_xxx, recognize a directive //go:cgo_xxx instead. The effect is the same as in the C compiler: accumulate text into a buffer and emit in the output file, where the linker will find and use it. lex.c, obj.c: Accept //go:linkname to control the external symbol name used for a particular top-level Go variable. This makes it possible to refer to C symbol names but also symbols from other packages. It has always been possible to do this from C and assembly. To drive home the point that this should not be done lightly, require import "unsafe" in any file containing //go:linkname. plive.c, reflect.c, subr.c: Hard-code that interfaces contain only pointers. This means code handling multiword values in the garbage collector and the stack copier can be deleted instead of being converted. This change is already present in the dev.garbage branch.

This is the source code repository for the Go programming language. For documentation about how to install and use Go, visit http://golang.org/ or load doc/install-source.html in your web browser. After installing Go, you can view a nicely formatted doc/install-source.html by running godoc --http=:6060 and then visiting http://localhost:6060/doc/install/source. Unless otherwise noted, the Go source files are distributed under the BSD-style license found in the LICENSE file. -- Binary Distribution Notes If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this README). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install.html). You should also add the Go binary directory $GOROOT/bin to your shell's path. For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile: export GOROOT=$HOME/go export PATH=$PATH:$GOROOT/bin See doc/install.html for more details.
