net/rpc: improve response reading logic CL 5956051 introduced too many call != nil checks, so attempt to improve this by splitting logic into three distinct parts. R=r CC=golang-dev http://codereview.appspot.com/6248048 Committer: Rob Pike <r@golang.org>

cmd/8c: better fix for 64-bit register smash Ken pointed out that CL 5998043 was ugly code. This should be better. Fixes issue 3501. R=ken2 CC=golang-dev http://codereview.appspot.com/6258049

cmd/gc: fix parallel assignment in range for expr1, expr2 = range slice was assigning to expr1 and expr2 in sequence instead of in parallel. Now it assigns in parallel, as it should. This matters for things like for i, x[i] = range slice. Fixes issue 3464. R=ken2 CC=golang-dev http://codereview.appspot.com/6252048

runtime: handle and test large map values This is from CL 5451105 but was dropped from that CL. See also CL 6137051. The only change compared to 5451105 is to check for h != nil in reflect·mapiterinit; allowing use of nil maps must have happened after that original CL. Fixes issue 3573.

exp/html: adjust parseForeignContent to match spec Remove redundant checks for integration points. Ignore null bytes in text. Don't break out of foreign content for a <font> tag unless it has a color, face, or size attribute. Check for MathML text integration points when breaking out of foreign content. Pass two new tests.

hash/adler32: optimize. The bulk of the gains come from hoisting the modulo ops outside of the inner loop.

net/rpc: fix race condition when request write partially fails When client fails to write a request is sends caller that error, however server might have failed to read that request in the mean time and replied with that error. When client then reads the response the call would no longer be pending, so call will be nil Handle this gracefully by discarding such server responses R=golang-dev, r CC=golang-dev, rsc http://codereview.appspot.com/5956051 Committer: Rob Pike <r@golang.org>

cmd/gc: faster code, mainly for rotate * Eliminate bounds check on known small shifts. * Rewrite x<<s | x>>(32-s) as a rotate (constant s). * More aggressive (but still minimal) range analysis. R=ken, dave, iant CC=golang-dev http://codereview.appspot.com/6209077

runtime: fix docs for Caller and Callers The previous attempt to explain this got it backwards (all the more reason to be sad we couldn't make the two functions behave the same). Fixes issue 3669. R=golang-dev, rsc CC=golang-dev http://codereview.appspot.com/6249051

exp/locale/collate: avoid 16-bit math There's no need for the 16-bit arithmetic here, and it tickles a long-standing compiler bug. Fix the exp code not to use 16-bit math and create an explicit test for the compiler bug. R=golang-dev, r CC=golang-dev http://codereview.appspot.com/6256048

math/big: make Rat.Denom() always return a reference The documentation says so, but in the case of a normalized integral Rat, the denominator was a new value. Changed the internal representation to use an Int to represent the denominator (with the sign ignored), so a reference to it can always be returned. Clarified documentation and added test cases. Fixes issue 3521. R=golang-dev, rsc CC=golang-dev http://codereview.appspot.com/6237045

cmd/6g: peephole fixes/additions * Shift/rotate by constant doesn't have to stop subprop. (also in 8g) * Remove redundant MOVLQZX instructions. * An attempt at issuing loads early. Good for 0.5% on a good day, might not be worth keeping. Need to understand more about whether the x86 looks ahead to what loads might be coming up.
