[09:34] 	<Rhy0lite <irc://irc.oftc.net/Rhy0lite,isnick>> 	zadeck_: with
your patch, gcc ppc will generate more pseudos for materializing
constants and splitting some logical ops
[09:34] 	<Rhy0lite <irc://irc.oftc.net/Rhy0lite,isnick>> 	which is good
[09:34] 	<Rhy0lite <irc://irc.oftc.net/Rhy0lite,isnick>> 	instead of
trying to do the operations in place with existing registers

read-write dependencies
