Russ Cox	0d82e69811	test: prepare for 64-bit ints ... Minor tweaks to avoid assuming that int is always 32 bits. Update #2188. R=golang-dev, r CC=golang-dev https://golang.org/cl/6553062	2012-09-24 00:06:41 -04:00
Russ Cox	cd22afa07b	test: expand run.go's errorcheck, make clear which bugs run ... Today, if run.go doesn't understand a test header line it just ignores the test, making it too easy to write or edit tests that are not actually being run. - expand errorcheck to accept flags, so that bounds.go and escape*.go can run. - create a whitelist of skippable tests in run.go; skipping others is an error. - mark all skipped tests at top of file. Update #4139. R=golang-dev, bradfitz CC=golang-dev https://golang.org/cl/6549054	2012-09-23 13:16:14 -04:00
Russ Cox	c6ce44822c	cmd/gc: faster code, mainly for rotate ... * Eliminate bounds check on known small shifts. * Rewrite x<<s | x>>(32-s) as a rotate (constant s). * More aggressive (but still minimal) range analysis.
