68f57c8327 androidtest.bash: copy pkg for gcimporter tests
The tests for go/types depend on reading gc export data from the
$GOROOT/pkg directory. This is the first use of these files as
testdata, so previously they were not copied to the android device.
Now they are used, copy them.

Fixes android/arm build.

a173357cd5 runtime: fix return type for bsdthread_register in comments
The return type for bsdthread_register is int32. See
runtime/os_darwin.go.

This change also rewrites declaration comments for go functions to
use go syntax and fixes vet errors in sys_darwin_amd64.s.

a814c05eba io: clarify Copy docs regarding error handling
"returns ... the first error" was misleading or at least confusing:
in case a Read results in an error with non-zero bytes read, and the
subsequent Write also results in an error, the error from Write is
returned, which is the second one (in the temporal dimension).

Fixes #9744

b2a1fb74f4 cmd/api: update api checker to use go/types from std repo
The old code checked out a specific version of go/types from the
x/tools repo. With go/types being part of the std repo, this is
not necessary anymore.

Also, for the same reason, the api tool is now built like any
other regular command. There's no need to build it for each run.
Removed the respective +build tags.

254964074f go/types, go/exact: "vendor" go/types into std repo
This is a first step towards moving go/types from the tools
repo into the std repo. The files were brought over via the
added src/go/types.bash script for reproducability. The
script can be removed once all dependencies on go/types
have moved to the std repo go/types.

The script moved packages as follows:

- x/tools/go/types => go/types (type-checker)
- x/tools/go/exact => go/exact (constants)
- x/tools/go/gcimporter => go/types/internal/gcimporter

The gcimporter is needed to be able to run tests. go/types
should probably have some factory function to provide an
appropriate importer.

Some of the go/types tests fail for a handful of platforms
(windows and nacl). In order to keep this change "clean"
from manual changes, the next change will disable those
tests for now so we can move forward.

bb418a59f8 cmd/internal/gc: use approx. float formatting in error messages
For very out-of-range floating-point constants (1e100000000),
precise formatting of the offending value for error messages
is not needed and potentially extremely slow.

This change resurrects an adjusted variant of the original code
which uses float64 formatting in the common case (in-range values),
and a fast manual approximation for out-of-range values.

8e95654ac8 net/url: allow Parse, ParseRequestURI to parse ipv6 zone identifiers in URIs
Using IPv6 link-local addresses to make connections between on-link
nodes is useful for small distributed applications but it requires zone
identifiers to distinguish a correct IP link. It's the same for
transports using URI for destination discovery such as HTTP, WebSocket.

This change allows Parse, ParseRequestURI functions and String method of
URL to parse/return a literal IPv6 address followed by a zone identifier
within a URI as described in RFC 6874.

Fixes #6530.

5451fff475 doc/progs: rewrite test driver in Go
The tests in doc/progs appear to have been originally written
for use with the old test driver. At some later point,
they acquired their own test driver.
Both ran tests in serial.

This CL rewrites the current test driver in Go,
runs tests concurrently, and cleans up
historical artifacts from the old drivers.

The primary motivation is to speed up all.bash.
On my laptop, using tip, this CL reduces doc/progs test
wall time from 26s to 7s. The savings will remain
even when the compiler gets faster. Using Go 1.4,
this CL reduces test wall time from 15s to 4s.

8c3fc088fb runtime: report marked heap size in gctrace
When the gctrace GODEBUG option is enabled, it will now report three
heap sizes: the heap size at the beginning of the GC cycle, the heap
size at the end of the GC cycle before sweeping, and marked heap size,
which is the amount of heap that will be retained until the next GC
cycle.

6d12b1780e runtime: make next_gc be heap size to trigger GC at
In the STW collector, next_gc was both the heap size to trigger GC at
as well as the goal heap size.

Early in the concurrent collector's development, next_gc was the goal
heap size, but was also used as the heap size to trigger GC at. This
meant we always overshot the goal because of allocation during
concurrent GC.

Currently, next_gc is still the goal heap size, but we trigger
concurrent GC at 7/8*GOGC heap growth. This complicates
shouldtriggergc, but was necessary because of the incremental
maintenance of next_gc.

Now we simply compute next_gc for the next cycle during mark
termination. Hence, it's now easy to take the simpler route and
redefine next_gc as the heap size at which the next GC triggers. We
can directly compute this with the 7/8 backoff during mark termination
and shouldtriggergc can simply test if the live heap size has grown
over the next_gc trigger.

This will also simplify later changes once we start setting next_gc in
more sophisticated ways.
