Russ Cox	d4cc557b0d	runtime: use manual stack for garbage collection ... Old code was using recursion to traverse object graph. New code uses an explicit stack, cutting the per-pointer footprint to two words during the recursion and avoiding the standard allocator and stack splitting code. in test/garbage: Reduces parser runtime by 2-3% Reduces Peano runtime by 40% Increases tree runtime by 4-5% R=r CC=golang-dev https://golang.org/cl/2150042	2010-09-07 09:57:22 -04:00
Russ Cox	12518e441b	runtime cleanup. ... * move memory code into $GOOS-specific directory. * allow printing of static strings < 256 bytes. (dynamic strings will bump maxstring as they are allocated.) * use cgo2c for runtime.mal. R=r, dho CC=golang-dev https://golang.org/cl/186143	2010-01-13 17:50:02 -08:00
