image: rename image.Tiled to image.Repeated. · 415f15b6

Nigel Tao authored Jan 11, 2012

What package image currently provides is a larger image consisting
of many copies of a smaller image.

More generally, a tiled image could be a quilt consisting of different
smaller images (like Google Maps), or a technique to view a portion of
enormous images without requiring the whole thing in memory.

This richer construct might not ever belong in the standard library (and
is definitely out of scope for Go 1), but I would like the option for
image.Tiled to be its name.

gc: inlining fixes · 97fd7d5f

Luuk van Dijk authored Jan 10, 2012

flag -l means: inlining on, -ll inline with early typecheck
-l lazily typechecks imports on use and re-export, nicer for debugging
-lm produces output suitable for errchk tests, repeated -mm... increases inl.c's verbosity
export processed constants, instead of originals
outparams get ->inlvar too, and initialized to zero
fix shared rlist bug, that lead to typecheck messing up the patched tree
properly handle non-method calls to methods T.meth(t, a...)
removed embryonic code to handle closures in inlined bodies
also inline calls inside closures (todo: move from phase 6b to 4)

Fixes #2579.

math/big: simplify fast string conversion · b4be65bc

Robert Griesemer authored Jan 09, 2012

- use slice ops for convertWords instead of lo/hi boundaries
- always compute leading zeroes (simplifies logic significantly),
  but remove them once, at the end (since leafSize is small, the
  worst-case scenario is not adding significant overhead)
- various comment cleanups (specifically, replaced direct -> iterative,
  and indirect -> recursive)
- slightly faster overall for -bench=String

go-mode.el: fix syntax highlighting of backticks · 70ed0ac5

Florian Weimer authored Jan 09, 2012

Instead of syntax-tables, an extended go-mode-cs is used for
from a font-lock callback.

Cache invalidation must happen in a before-change-function
because font-lock runs in an after-change-function, potentially
before the cache invalidation takes place.

Performance is reasonable, even with src/pkg/html/entity.go
and test/fixedbugs/bug257.go.
