* Revert 101465, it broke internal OpenGL testing.Eric Christopher2010-04-161-2/+2
| | | | | | | Probably the best way to know that all getOperand() calls have been handled is to replace that API instead of updating. llvm-svn: 101579
* reapply r101434Gabor Greif2010-04-161-2/+2
| | | | | | | | | | | | | with a fix for self-hosting rotate CallInst operands, i.e. move callee to the back of the operand array the motivation for this patch are laid out in my mail to llvm-commits: more efficient access to operands and callee, faster callgraph-construction, smaller compiler binary llvm-svn: 101465
* back out r101423 and r101397, they break llvm-gcc self-host on darwin10Gabor Greif2010-04-161-2/+2
| | | | llvm-svn: 101434
* reapply r101364, which has been backed out in r101368Gabor Greif2010-04-151-2/+2

* Move GetStringLength and helper from SimplifyLibCalls to ValueTracking.Eric Christopher2010-03-051-0/+129
| | | | | | No functionality change. llvm-svn: 97793
* There are two ways of checking for a given type, for example isa<PointerType>(T)Duncan Sands2010-02-161-6/+6
| | | | | | | and T->isPointerTy(). Convert most instances of the first form to the second form. Requested by Chris. llvm-svn: 96344
* Uniformize the names of type predicates: rather than having isFloatTy andDuncan Sands2010-02-151-8/+8
| | | | | | isInteger, we now have isFloatTy and isIntegerTy. Requested by Chris! llvm-svn: 96223
* It looks like the changes to the SRem logic of SimplifyDemandedUseBitsDuncan Sands2010-01-291-8/+17
| | | | | | (fix for PR6165) are needed here too. llvm-svn: 94801

| | | | llvm-svn: 92964
* Move remaining stuff to the isInteger predicate.Benjamin Kramer2010-01-051-3/+2
| | | | llvm-svn: 92771
* Fix GetConstantStringInfo to not look into MDString (it works on Chris Lattner2009-12-151-5/+0
| | | | | | | real data, not metadata) and fix DbgInfoPrinter to not abuse GetConstantStringInfo. llvm-svn: 91444

* Implement PR1143 (at -m64) by making basicaa look through extensions. WeChris Lattner2009-11-261-2/+23
| | | | | | | previously already handled it at -m32 because there were no i32->i64 extensions for addressing. llvm-svn: 89959

* Use hasDefinitiveInitializer() instead of testing the same thingDan Gohman2009-08-191-2/+1

* Add a new Operator class, for handling Instructions and ConstantExprsDan Gohman2009-07-171-20/+9
| | | | | | | | | in a convenient manner, factoring out some common code from InstructionCombining and ValueTracking. Move the contents of BinaryOperators.h into Operator.h and use Operator to generalize them to support ConstantExprs as well as Instructions. llvm-svn: 76232

| | | | | | | | | While we could do this, doing so requires adjusting the demanded mask and the code isn't doing that yet. This fixes PR4495 llvm-svn: 74699
* Fix llvm::ComputeNumSignBits to handle pointer typesDan Gohman2009-06-221-1/+5

* Support vector casts in more places, fixing a variety of assertionDan Gohman2009-06-151-10/+25
| | | | | | | | | | | | | | | failures. To support this, add some utility functions to Type to help support vector/scalar-independent code. Change ConstantInt::get and ConstantFP::get to support vector types, and add an overload to ConstantInt::get that uses a static IntegerType type, for convenience. Introduce a new getConstant method for ScalarEvolution, to simplify common use cases. llvm-svn: 73431
* Split the Add, Sub, and Mul instruction opcodes into separateDan Gohman2009-06-041-1/+1
| | | | | | | | | | | | | | | integer and floating-point opcodes, introducing FAdd, FSub, and FMul. For now, the AsmParser, BitcodeReader, and IRBuilder all preserve backwards compatability, and the Core LLVM APIs preserve backwards compatibility for IR producers. Most front-ends won't need to change immediately. This implements the first step of the plan outlined here: http://nondot.org/sabre/LLVMNotes/IntegerOverflow.txt llvm-svn: 72897
