sse2 is a more precise description of the requirement,
and it matches what people will see in, for example
        grep sse2 /proc/cpuinfo # linux
        sysctl hw.optional.sse2 # os x

Decode as much as possible of a Huffman symbol in a single table
lookup (much like the zlib implementation), filling more bits
(conservatively, so we don't consume past the end of the stream)
when the code prefix indicates more bits are needed. This
results in about a 50% performance gain in speed benchmarks.
The following set is benchcmp done on a retina MacBook Pro:

I think that the parser is complete enough to take that warning out.
It passes the test suite.
There may be incompatible API changes, but being in the exp directory
is warning enough for that.

We need to wait for the handler to actually finish running,
not almost be done running.

This was always a bug, but now that handler output is buffered
it shows up easily on GOMAXPROCS >1 systems.

It's possible to view the package docs in plain text, eg:
        http://golang.org/pkg/time/?m=text
and this CL introduces the ability to do the same for files:

Completely removed *ast.Objects from being exposed by the
types API. *ast.Objects are still required internally for
resolution, but now the door is open for an internal-only
rewrite of identifier resolution entirely at type-check
time. Once that is done, ASTs can be type-checked whether
they have been created via the go/parser or otherwise,
and type-checking does not require *ast.Object or scope
invariants to be maintained externally.
