* all: merge dev.garbage (d1238958d4ae) into default branchRuss Cox2014-12-0521-261/+67
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | When we start work on Gerrit, ppc64 and garbage collection work will continue in the master branch, not the dev branches. (We may still use dev branches for other things later, but these are ready to be merged, and doing it now, before moving to Git means we don't have to have dev branches working in the Gerrit workflow on day one.)

| * runtime: generate windows callback list with go generateRuss Cox2014-12-054-200/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the last system-dependent file written by cmd/dist. They are all now written by go generate. cmd/dist is not needed to start building package runtime for a different system anymore. Now all the generated files can be assumed generated, so delete the clumsy hacks in cmd/api. Re-enable api check in run.bash.

In lieu of an actual barrier, writebarrierptr checks that the value being copied is not a small non-zero integer. This is enough to shake out bugs where the barrier is being called when it should not (for non-pointer values). It also found a few tests in sync/atomic that were being too clever. This CL adds a write barrier for the memory moved during the builtin copy function, which I forgot when inserting barriers for Go 1.4. This CL re-enables some write barriers that were disabled for Go 1.4. Those were disabled because it is possible to change the generated code so that they are unnecessary most of the time, but we have not changed the generated code yet. For safety they must be enabled. None of this is terribly efficient. We are aiming for correct first. LGTM=rlh R=rlh CC=golang-codereviews https://codereview.appspot.com/168770043

Note the issue isn't long "//go:generate" lines, but any long line in any Go source file. To be fair, if you're going to have a stupid long line it's not a bad bet you'll want to run it through go generate, because it's some embeddable asset that has been machine generated. (One could ask why that generation process didn't add a newline or two, but we should cope anyway.) Rewrite the file scanner in "go generate" so it can handle arbitrarily long lines, and only stores in memory those lines that start "//go:generate". Also: Adjust the documentation to make clear that it does not parse the file. Fixes issue 9143. Fixes issue 9196.

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.

The only thing cmd/dist really needs to do is write things like the current experiment info and the current version. This is a first step toward that. It replaces the _NaCl etc constants with generated ones goos_nacl, goos_darwin, goarch_386, and so on.

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.
