2011-01-21Enable support for precise scheduling of the instruction selectionAndrew Trick
DAG. Disable using "-disable-sched-cycles". For ARM, this enables a framework for modeling the cpu pipeline and counting stalls. It also activates several heuristics to drive scheduling based on the model. Scheduling is inherently imprecise at this stage, and until spilling is improved it may defeat attempts to schedule. However, this framework provides greater control over tuning codegen. Although the flag is not target-specific, it should have very little affect on the default scheduler used by x86. The only two changes that affect x86 are: - scheduling a high-latency operation bumps the current cycle so independent operations can have their latency covered. i.e. two independent 4 cycle operations can produce results in 4 cycles, not 8 cycles. - Two operations with equal register pressure impact and no latency-based stalls on their uses will be prioritized by depth before height (height is irrelevant if no stalls occur in the schedule below this point). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123971 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-21Convert -enable-sched-cycles and -enable-sched-hazard to -disableAndrew Trick
flags. They are still not enable in this revision. Added TargetInstrInfo::isZeroCost() to fix a fundamental problem with the scheduler's model of operand latency in the selection DAG. Generalized unit tests to work with sched-cycles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123969 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-20Don't be overly aggressive with CSE of "ldr constantpool". If it's a pc-relativeEvan Cheng
value, the "add pc" must be CSE'ed at the same time. We could follow the same approach as T2 by adding pseudo instructions that combine the ldr + "add pc". But the better approach is to use movw + movt (which I will enable soon), so I'll leave this as a TODO. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123949 91177308-0d34-0410-b5e6-96231b3b80d8

to add/sub by doing the normal operation and then checking for overflow afterwards. This generally relies on the DAG handling the later invalid operations as well.
