Russ Cox	d42495aa80	cmd/cc: add PREFETCH built-in (like SET, USED) ... This makes it possible to inline the prefetch of upcoming memory addresses during garbage collection, instead of needing to flush registers, make a function call, and reload registers. On garbage collection-heavy workloads, this results in a 5% speedup. Fixes #3493. R=dvyukov, ken, r, dave CC=golang-dev https://golang.org/cl/5990066	2012-05-02 16:22:56 -04:00
