* Generalize target-independent folding rules for sizeof to handle moreDan Gohman2010-02-013-40/+98
| | | | | | | | | | | | | | | | | | | | cases, and implement target-independent folding rules for alignof and offsetof. Also, reassociate reassociative operators when it leads to more folding. Generalize ScalarEvolution's isOffsetOf to recognize offsetof on arrays. Rename getAllocSizeExpr to getSizeOfExpr, and getFieldOffsetExpr to getOffsetOfExpr, for consistency with analagous ConstantExpr routines. Make the target-dependent folder promote GEP array indices to pointer-sized integers, to make implicit casting explicit and exposed to subsequent folding. And add a bunch of testcases for this new functionality, and a bunch of related existing functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94987 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove SCEVAllocSizeExpr and SCEVFieldOffsetExpr, and in their placeDan Gohman2010-01-282-105/+100
| | | | | | | | | | | | | | | | | use plain SCEVUnknowns with ConstantExpr::getSizeOf and ConstantExpr::getOffsetOf constants. This eliminates a bunch of special-case code. Also add code for pattern-matching these expressions, for clients that want to recognize them. Move ScalarEvolution's logic for expanding array and vector sizeof expressions into an element count times the element size, to expose the multiplication to subsequent folding, into the regular constant folder. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94737 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix inline cost predictions with SCIENCE.Jakob Stoklund Olesen2010-01-261-28/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | After running a batch of measurements, it is clear that the inliner metrics need some adjustments: Own argument bonus: 20 -> 5 Outgoing argument penalty: 0 -> 5 Alloca bonus: 10 -> 5 Constant instr bonus: 7 -> 5 Dead successor bonus: 40 -> 5*(avg instrs/block) The new cost metrics are generaly 25 points higher than before, so we may need to move thresholds. With this change, InlineConstants::CallPenalty becomes a political correction: if (!isa<IntrinsicInst>(II) && !callIsSmall(CS.getCalledFunction())) NumInsts += InlineConstants::CallPenalty + CS.arg_size(); The code size is accurately modelled by CS.arg_size(). CallPenalty is added because calls tend to take a long time, so it may not be worth it to inline a function with lots of calls. All of the political corrections are in the InlineConstants namespace: IndirectCallBonus, CallPenalty, LastCallToStaticBonus, ColdccPenalty, NoreturnPenalty. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94615 91177308-0d34-0410-b5e6-96231b3b80d8
* Revert test polarity to match comment and desired outcome. Remove undeserved ↵Jakob Stoklund Olesen2010-01-261-2/+2

This patch should remove a small positive bias toward inlining functions with variable-index GEPs, and remove a smaller negative bias from functions with all-constant index GEPs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94591 91177308-0d34-0410-b5e6-96231b3b80d8

* Re-implement the main strength-reduction portion of LoopStrengthReduction.Dan Gohman2010-01-213-81/+359
| | | | | | | | | | | | | | | This new version is much more aggressive about doing "full" reduction in cases where it reduces register pressure, and also more aggressive about rewriting induction variables to count down (or up) to zero when doing so reduces register pressure. It currently uses fairly simplistic algorithms for finding reuse opportunities, but it introduces a new framework allows it to combine multiple strategies at once to form hybrid solutions, instead of doing all full-reduction or all base+index. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94061 91177308-0d34-0410-b5e6-96231b3b80d8
