Owen Anderson e1cebd9e2e Replace the statically generated hashtables for checking register relationships with just scanning the (typically tiny) static lists. ... At the time I wrote this code (circa 2007), TargetRegisterInfo was using a std::set to perform these queries. Switching to the static hashtables was an obvious improvement, but in reality there's no reason to do anything other than scan. With this change, total LLC time on a whole-program 403.gcc is reduced by approximately 1.5%, almost all of which comes from a 15% reduction in LiveVariables time. It also reduces the binary size of LLC by 86KB, thanks to eliminating a bunch of very large static tables. llvm-svn: 133051		2011-06-15 06:53:50 +00:00

Analysis	Add "unknown" results for memdep, which mean "I don't know whether a dependence for the given instruction exists in the given block". This cleans up all the existing hacks in memdep which represent this concept by returning clobber with various unrelated instructions.	2011-06-15 00:47:34 +00:00
