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
