The new flag was added by CL 68150047 (part of the NaCl replay),
but the change, like the original, omitted documentation of the
new behavior.

See golang.org/s/go13nacl for design overview.
This CL is the mostly mechanical changes from rsc's Go 1.2 based NaCl branch, specifically 39cb35750369 to 500771b477cf from https://code.google.com/r/rsc-go13nacl. This CL does not include working NaCl support, there are probably two or three more large merges to come.
CL 15750044 is not included as it involves more invasive changes to the linker which will need to be merged separately.
The exact change lists included are
15050047: syscall: support for Native Client
15360044: syscall: unzip implementation for Native Client
15370044: syscall: Native Client SRPC implementation
15400047: cmd/dist, cmd/go, go/build, test: support for Native Client
15410048: runtime: support for Native Client
15410049: syscall: file descriptor table for Native Client
15410050: syscall: in-memory file system for Native Client
15440048: all: update +build lines for Native Client port
15540045: cmd/6g, cmd/8g, cmd/gc: support for Native Client
15570045: os: support for Native Client
15680044: crypto/..., hash/crc32, reflect, sync/atomic: support for amd64p32
15690044: net: support for Native Client
15690048: runtime: support for fake time like on Go Playground
15690051: build: disable various tests on Native Client

This CL adds a test that calls Mmap and Munmap through Syscall9
as the canary that detects assembly fragment breakage. For now
there is no package test that uses Syscall9 in the standard
library across all Unix-like systems.
Note that the package runtime owns its assembly fragments, so
this canary never works for runtime breakage.

Currently an ECDHE handshake uses the client's curve preference. This
generally means that we use P-521. However, P-521's strength is
mismatched with the rest of the cipher suite in most cases and we have
a fast, constant-time implementation of P-256.
With this change, Go servers will use P-256 where the client supports
it although that can be overridden in the Config.

Revision c0e0467635ec (cmd/gc: return canonical Node* from temp)
exposed original nodes of temporaries, allowing callers to mutate
their types.
In walkcompare a temporary could be typed as ideal because of
this. Additionnally, assignment of a comparison result to
a custom boolean type was broken.

Fixes the output of go env so that variables can be set
more accurately when using Plan 9's rc shell. Specifically,
GOPATH may have multiple components and the current
representation is plain wrong. In practice, we probably
ought to change os. Getenv to produce the right result, but
that requires considerably more thought.

Update #7347
When runtime.panic is called the *Panic is malloced from the heap. This can lead to a gc cycle while panicing which can make a bad situation worse.
It appears to be possible to stack allocate the Panic and avoid malloc'ing during a panic.

This lays the groundwork for making Go robust when the system's
calendar time jumps around. All input values to the runtimeTimer
struct now use the runtime clock as a common reference point.
This affects net.Conn.Set[Read|Write]Deadline(), time.Sleep(),
time.Timer, etc. Under normal conditions, behavior is unchanged.
Each platform and architecture's implementation of runtime·nanotime()
should be modified to use a monotonic system clock when possible.
Platforms/architectures modified and tested with monotonic clock:
linux/x86 - clock_gettime(CLOCK_MONOTONIC)
