2012-11-15[reg scavenger] Fix the isUsed/isAliasUsed functions so as to not report a falseChad Rosier
positive. In this particular case, R6 was being spilled by the register scavenger when it was in fact dead. The isUsed function reported R6 as used because the R6_R7 alias was reserved (due to the fact that we've reserved R7 as the FP). The solution is to only check if the original register (i.e., R6) isReserved and not the aliases. The aliases are only checked to make sure they're available. The test case is derived from one of the nightly tester benchmarks and is rather intractable and difficult to reproduce, so I haven't included it. rdar://12592448 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168054 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-13misched: Allow subtargets to enable misched and dependent options.Andrew Trick
This allows me to begin enabling (or backing out) misched by default for one subtarget at a time. To run misched we typically want to: - Disable SelectionDAG scheduling (use the source order scheduler) - Enable more aggressive coalescing (until we decide to always run the coalescer this way) - Enable MachineScheduler pass itself. Disabling PostRA sched may follow for some subtargets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167826 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-13Added RegisterCoalescer support for joining global copies first.Andrew Trick
This adds the -join-globalcopies option which can be enabled by default once misched is also enabled. Ideally, the register coalescer would be able to split local live ranges in a way that produces copies that can be easily resolved by the scheduler. Until then, this heuristic should be good enough to at least allow the scheduler to run after coalescing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167825 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-13misched: Don't consider artificial edges weak edges.Andrew Trick
For now be more conservative in case other out-of-tree schedulers rely on the old behavior of artificial edges. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167808 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-13Use the 'count' attribute instead of the 'upper_bound' attribute.Bill Wendling
If we have a type 'int a[1]' and a type 'int b[0]', the generated DWARF is the same for both of them because we use the 'upper_bound' attribute. Instead use the 'count' attrbute, which gives the correct number of elements in the array. <rdar://problem/12566646> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167806 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-12Added a temporary option to avoid critical edges splitting.Andrew Trick
This teaches the register coalescer to be less prone to split critical edges. I am currently benchmarking this with the new (post-coalescer) scheduler. I plan to enable this by default and remove the option as soon as misched is enabled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167758 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-12misched: Target-independent support for MacroFusion.Andrew Trick
Uses the infrastructure from r167742 to support clustering instructure that the target processor can "fuse". e.g. cmp+jmp. Next step: target hook implementations with test cases, and enable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167744 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-12misched: Target-independent support for load/store clustering.Andrew Trick
This infrastructure is generally useful for any target that wants to strongly prefer two instructions to be adjacent after scheduling. A following checkin will add target-specific hooks with unit tests. Then this feature will be enabled by default with misched. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167742 91177308-0d34-0410-b5e6-96231b3b80d8
