Andrew Trick 16bb45c5c8 mi-sched: Suppress register pressure tracking when the scheduling window is too small. ... If the instruction window is < NumRegs/2, pressure tracking is not likely to be effective. The scheduler has to process a very large number of tiny blocks. We want this to be fast. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189991 91177308-0d34-0410-b5e6-96231b3b80d8		2013-09-04 21:00:11 +00:00
