      encoding/json: add an example for RawMessage · 08570458
      Josh Bleecher Snyder authored 
      RawMessage is useful and mildly non-obvious.
Given the frequency with which RawMessage questions
show up on golang-nuts, and get answered with an example,
I suspect adding an example to the docs might help.

      runtime: fix finalizer test on amd64 · 5f853d7d
      Russ Cox authored 
      Not scanning the stack by frames means we are reintroducing
a few false positives into the collection. Run the finalizer registration
in its own goroutine so that stack is guaranteed to be out of
consideration in a later collection.

This is working around a regression from yesterday's tip, but
it's not a regression from Go 1.1.

      runtime: do not scan stack by frames during garbage collection · c3dadca9
      Russ Cox authored 
      Walking the stack by frames is ~3x more expensive
than not, and since it didn't end up being precise,
there is not enough benefit to outweigh the cost.

This is the conservative choice: this CL makes the
stack scanning behavior the same as it was in Go 1.1.

Add benchmarks to package runtime so that we have
them when we re-enable this feature during the
Go 1.3 development.

As far as I can tell the changes are mainly noise.

      cmd/dist, build: support building statically linked toolchain · 6b188ef5
      Shenghou Ma authored 
      Added a new $GO_DISTFLAGS to make.bash, and while we're here,
added mention $CXX in make.bash (CL 13704044).

Fixes #6448.
Update #3564
We can pass GO_DISTFLAGS=-s from misc/dist to make.bash so that
it will build a statically linked toolchain.
(Note: OS X doesn't have the concept of static linking, so don't
pass GO_DISTFLAGS=-s for OS X builds)

      Currently, the directories generaed by includeArgs can have the "_race"
suffix added if invoked with -race flag, but ignores -installsuffix if
set.
