* Added MachineSchedPolicy.Andrew Trick2013-09-061-0/+11
| | | | | | | | Allow subtargets to customize the generic scheduling strategy. This is convenient for targets that don't need to add new heuristics by specializing the strategy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190176 91177308-0d34-0410-b5e6-96231b3b80d8
* Add useAA() to TargetSubtargetInfoHal Finkel2013-08-291-0/+4
| | | | | | | | | | | | | There are several optional (off-by-default) features in CodeGen that can make use of alias analysis. These features are important for generating code for some kinds of cores (for example the (in-order) PPC A2 core). This adds a useAA() function to TargetSubtargetInfo to allow these features to be enabled by default on a per-subtarget basis. Here is the first use of this function: To control the default of the -enable-aa-sched-mi feature. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189563 91177308-0d34-0410-b5e6-96231b3b80d8
* Use the 'target-features' and 'target-cpu' attributes to reset the subtarget ↵Bill Wendling2013-02-151-0/+4
| | | | | | | | | | | features. If two functions require different features (e.g., `-mno-sse' vs. `-msse') then we want to honor that, especially during LTO. We can do that by resetting the subtarget's features depending upon the 'target-feature' attribute. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175314 91177308-0d34-0410-b5e6-96231b3b80d8
* misched: Allow subtargets to enable misched and dependent options.Andrew Trick2012-11-131-0/+7
| | | | | | | | | | | | 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
