Timings (as for change 1122043) go from 49ms to 48ms ish. It's mostly lost in the noise, but it probably doesn't hurt. R=r CC=golang-dev http://codereview.appspot.com/1179041

To draw.Draw a 32x32 image.Alpha 10000 times, Before: 633ms with 10000 mallocs After: 49ms with 0 mallocs These times are just blitting an image.Alpha, and do not include rasterizing a glyph's vector contours to an image.Alpha.

2010-05-08big: cleanups and performance tuningRobert Griesemer5-161/+142
- removed last argument (n) from all core arithmetic routines; instead, use the length of the result - simplified nat.make implementation and chose a better capacity for new values, removed a TODO in the process Changing the constant e from 1 (old) to 4 (new) improved pidigits -s -n 10000 by ~9% (on a 3.06GHz Intel Core 2 Duo): user 0m3.882s (old) user 0m3.549s (new) R=rsc CC=golang-dev http://codereview.appspot.com/1133043

2010-05-06big: implemented overlap-tolerant shifts in assemblyRobert Griesemer5-164/+188
- no need to make copies in cases of aliases - removed deprecated internal shift functions - minor unrelated simplifications This change improves pidigits -s -n10000 by almost 20%: user 0m6.156s (old) user 0m4.999s (new) (pidigits -s -n20000 goes from ~25s to ~19s) R=rsc CC=golang-dev http://codereview.appspot.com/1149041

2010-05-05gob: add support for maps.Rob Pike6-43/+254
Because maps are mostly a hidden type, they must be implemented using reflection values and will not be as efficient as arrays and slices. R=rsc CC=golang-dev http://codereview.appspot.com/1127041

- renamed Len -> BitLen, simplified implementation - renamed old Div, Mod, DivMod -> Que, Rem, QuoRem - implemented Div, Mod, DivMod (Euclidian definition, more useful in a mathematical context) - fixed a bug in Exp (-0 was possible) - added extra tests to check normalized results everywhere - uniformly set Int.neg flag at the end of computations - minor cosmetic cleanups - ran all tests R=rsc CC=golang-dev http://codereview.appspot.com/1091041

2010-05-03runtime: update godefs usage comment for GOARCH=386 GOOS={darwin,freebsd}Giles Lean4-4/+4
When trying to regenerate src/pkg/runtime/darwin/386/defs.h on a 64 bit capable Snow Leopard (OS X 10.6.3) system I needed to add -f -m32 to godefs, as this OS and hardware combination defaults to 64 bit compilation. For safety, make the same change to the 32 bit FreeBSD instructions in .../freebsd/defs.c. (Tested OK and no problems introduced.)
