Andrew Trick 7db197d209 Increased the register pressure limit on x86_64 from 8 to 12 ... regs. This is the only change in this checkin that may affects the default scheduler. With better register tracking and heuristics, it doesn't make sense to artificially lower the register limit so much. Added -sched-high-latency-cycles and X86InstrInfo::isHighLatencyDef to give the scheduler a way to account for div and sqrt on targets that don't have an itinerary. It is currently defaults to 10 (the actual number doesn't matter much), but only takes effect on non-default schedulers: list-hybrid and list-ilp. Added several heuristics that can be individually disabled for the non-default sched=list-ilp mode. This helps us determine how much better we can do on a given benchmark than the default scheduler. Certain compute intensive loops run much faster in this mode with the right set of heuristics, and it doesn't seem to have much negative impact elsewhere. Not all of the heuristics are needed, but we still need to experiment to decide which should be disabled by default for sched=list-ilp. llvm-svn: 127067		2011-03-05 08:00:22 +00:00
