Evan Cheng	c9cb37516d	Teach if-converter to be more careful with predicating instructions that would ... take multiple cycles to decode. For the current if-converter clients (actually only ARM), the instructions that are predicated on false are not nops. They would still take machine cycles to decode. Micro-coded instructions such as LDM / STM can potentially take multiple cycles to decode. If-converter should take treat them as non-micro-coded simple instructions. llvm-svn: 113570	2010-09-10 01:29:16 +00:00
