* Revert some parts of r196288 that were confusing and untested.David Blaikie2014-10-141-8/+2
| | | | | | | If we figure out why they should be here, let's add some testing of some kind so we can better demonstrate why it's needed. llvm-svn: 219694

* Add an assertion about the integrity of the iterator.Adrian Prantl2014-10-131-0/+5
| | | | | | | | | Broken parent scope pointers in inlined DIVariables can cause ensureAbstractVariableIsCreated to insert new abstract scopes, thus invalidating the iterator in this loop and leading to hard-to-debug crashes. Useful when manually reducing IR for testcases. llvm-svn: 219628

| | | | | | | | | | | instructions within a function, lead to the function itself." This invariant is violated (& the assertions fire) on some Objective C++ in the test-suite. Reverting while I investigate. This reverts commit r219215. llvm-svn: 219523
* [MiSched] Fix a logic error in tryPressure()Hal Finkel2014-10-101-2/+2
| | | | | | | | | | | | | Fixes a logic error in the MachineScheduler found by Steve Montgomery (and confirmed by Andy). This has gone unfixed for months because the fix has been found to introduce some small performance regressions. However, Andy has recommended that, at this point, we fix this to avoid further dependence on the incorrect behavior (and then follow-up separately on any regressions), and I agree. Fixes PR18883. llvm-svn: 219512

* Improve sqrt estimate algorithm (fast-math)Sanjay Patel2014-10-091-17/+16
| | | | | | | | | | | | | | | | | | | This patch changes the fast-math implementation for calculating sqrt(x) from: y = 1 / (1 / sqrt(x)) to: y = x * (1 / sqrt(x)) This has 2 benefits: less code / faster code and one less estimate instruction that may lose precision. The only target that will be affected (until http://reviews.llvm.org/D5658 is approved) is PPC. The difference in codegen for PPC is 2 less flops for a single-precision sqrtf or vector sqrtf and 4 less flops for a double-precision sqrt. We also eliminate a constant load and extra register usage. Differential Revision: http://reviews.llvm.org/D5682 llvm-svn: 219445

* [PBQP] Replace PBQPBuilder with composable constraints (PBQPRAConstraint).Lang Hames2014-10-091-355/+307
| | | | | | | | | | | | | | | | This patch removes the PBQPBuilder class and its subclasses and replaces them with a composable constraints class: PBQPRAConstraint. This allows constraints that are only required for optimisation (e.g. coalescing, soft pairing) to be mixed and matched. This patch also introduces support for target writers to supply custom constraints for their targets by overriding a TargetSubtargetInfo method: std::unique_ptr<PBQPRAConstraints> getCustomPBQPConstraints() const; This patch should have no effect on allocations. llvm-svn: 219421

* Sink DwarfDebug::constructInlinedScopeDIE into DwarfCompileUnitDavid Blaikie2014-10-094-44/+50
| | | | | | | | | | | This introduces access to the AbstractSPDies map from DwarfDebug so DwarfCompileUnit can access it. Eventually this'll sink down to DwarfFile, but it'll still be generically accessible - not much encapsulation to provide it. (constructInlinedScopeDIE could stay further up, in DwarfFile to avoid exposing this - but I don't think that's particularly better) llvm-svn: 219411

* Sink DwarfDebug::addScopeRangeList down into DwarfCompileUnitDavid Blaikie2014-10-094-37/+43
| | | | | | | | | | | | | (& add a few accessors/make a couple of things public for this - it's a bit of a toss-up, but I think I prefer it this way, keeping some more of the meaty code down in DwarfCompileUnit - if only to make for smaller implementation files, etc) I think we could simplify range handling a bit if we removed the range lists from each unit and just put a single range list on DwarfDebug, similar to address pooling. llvm-svn: 219370
