use correct field count when resolving nameservers via /net/dns on Plan 9.
we incorrectly check for 4 fields instead of 3 when parsing the result of /net/dns, and get no results

constantly respawn each other (local runqueue never becomes empty).

It was used to request large stack segment for GC
when it was running not on g0.
Now GC is running on g0 with large stack,
and it is not needed anymore.

In Issue 5625, Russ says: "We should at least have a cache of
inflight lookups, so that 100 simultaneous dials of one host
name don't do the work 100x. That's easy and (assume we forget
the answer once they all get it) doesn't pose any consistency
problems. It just merges simultaneous work."
This brings in singleflight (unexported) from Google /
Camlistore, but without its tests. Maybe we should put it
somewhere in the standard library. But not now.
Update #5625

the address of the array but the memory access to the whole
memory range must be recorded instead.

Also set these fields in go/parser and use them in go/printer.

Default behavior is the same as before, but now a user may selectively disable some commands.
Also: deleted the mappings for import.vim.
Tested: by trying the commands for fmt, import and godoc in succession to make sure they still work. Also, ran test.sh in ftplugin/go.

Obscure misfeature now fixed: When run from "go test", profiles were always
written in the package's source directory. This change puts them in the directory
where "go test" is run.
Also fix a couple of problems causing errors in testing.after to go unreported
unless -v was set.

In starttheworld() we assume that P's with local work
are situated in the beginning of idle P list.
However, once we start the first M, it can execute all local G's
and steal G's from other P's.
That breaks the assumption above. Thus starttheworld() will fail
to start some P's with local work.
It seems that it can not lead to very bad things, but still
it's wrong and breaks other assumtions
(e.g. we can have a spinning M with local work).
The fix is to collect all P's with local work first,
and only then start them.

The garbage collection routine addframeroots is duplicating
logic in the traceback routine that calls it, sometimes correctly,
sometimes incorrectly, sometimes incompletely.
Pass necessary information to addframeroots instead of
deriving it anew.
Should make addframeroots significantly more robust.
It's certainly smaller.
Also try to standardize on uintptr for saved pc, sp values.
Will make CL 10036044 trivial.

This avoids problems with inlining in genwrappers, which
occurs after functions have been compiled. Compiling a
function may cause some unused local vars to be removed from
the list. Since a local var may be unused due to
optimization, it is possible that a removed local var winds up
beingused in the inlined version, in which case hilarity
ensues.
Fixes#5515.

It was off in the old implementation (because there was no high-level
description of the function at all). Maybe some day the race detector
should be fixed to handle the wrapper and then enabled for it, but there's
no reason that has to be today.

There's no reason to use a different name on each architecture,

the original Go runtime entry point. Rename it _rt0_go everywhere.

This feature is not yet ready for real use. The CL marks a bite-sized
piece that is ready for review. TODOs that remain:
provide control over output
produce output without setting -v
make work on reflect, sync and time packages
(fail now due to link errors caused by inlining)
better documentation
Almost all packages work now, though, if clumsily; try:
go test -v -cover=count encoding/binary
