2012-05-24misched: Give each ReadyQ a unique IDAndrew Trick
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157428 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-24misched: Added ScoreboardHazardRecognizer.Andrew Trick
The Hazard checker implements in-order contraints, or interlocked resources. Ready instructions with hazards do not enter the available queue and are not visible to other heuristics. The major code change is the addition of SchedBoundary to encapsulate the state at the top or bottom of the schedule, including both a pending and available queue. The scheduler now counts cycles in sync with the hazard checker. These are minimum cycle counts based on known hazards. Targets with no itinerary (x86_64) currently remain at cycle 0. To fix this, we need to provide some maximum issue width for all targets. We also need to add the concept of expected latency vs. minimum latency. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157427 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-23Add a last resort tryInstructionSplit() to RAGreedy.Jakob Stoklund Olesen
Live ranges with a constrained register class may benefit from splitting around individual uses. It allows the remaining live range to use a larger register class where it may allocate. This is like spilling to a different register class. This is only attempted on constrained register classes. <rdar://problem/11438902> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157354 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-23Fix typo in flag to opt, and also a CHECK-NEXT that doesn't follow aKaelyn Uhrain
CHECK. The latter error was hidden by the former, and the test harness used by e.g. "make check" silently ignored that opt was printing an error message about an unknown flag instead of running on the test file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157341 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-23Correctly deal with identity copies in RegisterCoalescer.Jakob Stoklund Olesen
Now that the coalescer keeps live intervals and machine code in sync at all times, it needs to deal with identity copies differently. When merging two virtual registers, all identity copies are removed right away. This means that other identity copies must come from somewhere else, and they are going to have a value number. Deal with such copies by merging the value numbers before erasing the copy instruction. Otherwise, we leave dangling value numbers in the live interval. This fixes PR12927. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157340 91177308-0d34-0410-b5e6-96231b3b80d8
