2010-01-29Change the SREM case to match the logic in the IR version ComputeMaskedBits.Duncan Sands
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94805 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-29Catch more trivial tail call opportunities: no inputs and output types match.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94804 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-29Having RHSKnownZero and RHSKnownOne be alternative names for KnownZero and ↵Duncan Sands
KnownOne (via APInt &RHSKnownZero = KnownZero, etc) seems dangerous and confusing to me: it is easy not to notice this, and then wonder why KnownZero/RHSKnownZero changed underneath you when you modified RHSKnownZero/KnownZero etc. So get rid of this. No intended functionality change (tested with "make check" + llvm-gcc bootstrap). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94802 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-29It looks like the changes to the SRem logic of SimplifyDemandedUseBitsDuncan Sands
(fix for PR6165) are needed here too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94801 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-29Quick fix to make the header file for the enhancedSean Callanan
disassembly information have a better comment (and better guard macros). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94781 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-29Added a bare-bones Makefile to build the enhanced disassemblySean Callanan
library as a static and a shared library. Added dependencies so the target-specific enhanced disassembly info tables are built before the library. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94780 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-29Add constant support to object size handling and remove defaultEric Christopher
lowering. We'll either figure it out, or not and be lowered by SelectionDAGBuild. Add test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94775 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94771 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-29Add newline to debugging output, and fix some grammar-os in comment.Bill Wendling
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94765 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-29Added a custom TableGen backend to support theSean Callanan
enhanced disassembler, and the necessary makefile rules to build the table for X86. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94764 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-28Assign the ordering of SDNodes in a much less intrusive fashion. After theBill Wendling
"visit*" method is called, take the newly created nodes, walk them in a DFS fashion, and if they don't have an ordering set, then give it one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94757 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-28Support some more options...Mikhail Glushenkov
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94752 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-28Remove the folding ruleDan Gohman
getelementptr (i8* inttoptr (i64 1 to i8*), i32 -1) to inttoptr (i64 0 to i8*) from the VMCore constant folder. It didn't handle sign-extension properly in the case where the source integer is smaller than a pointer size. And, it relied on an assumption about sizeof(i8). The Analysis constant folder still folds these kinds of things; it has access to TargetData, so it can do them right. Add a testcase which tests that the VMCore constant folder doesn't miscompile this, and that the Analysis folder does fold it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94750 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-28Fix PR6165. The bug was that LHSKnownZero was being and'd with DemandedMaskDuncan Sands
when it should have been and'd with LowBits. Fix that and while there beef up the logic in the case of a negative LHS. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94745 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-28Make getAlignOf return an i64, for consistency with getSizeOf andDan Gohman
getOffsetOf, and remove the comment about assuming i8 is byte-aligned, which is no longer applicable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94738 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-28Remove SCEVAllocSizeExpr and SCEVFieldOffsetExpr, and in their placeDan Gohman
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
