get method - For SCEVUnknown, this just gets and returns a new SCEVUnknown. Definition at line 1007 of file ScalarEvolution.cpp. References llvm::SCEVConstant::get(). Referenced by llvm::SCEVUDivExpr::get(), llvm::SCEVZeroExtendExpr::get(), llvm::SCEVTruncateExpr::get(), getIntegerSCEV(), getNegativeSCEV(), llvm::SCEVAddRecExpr::getNumIterationsInRange(), and PartialFact(). |
|
getIntegerSCEV - Given an integer or FP type, create a constant for the specified signed integer value and return a SCEV for the constant. Definition at line 397 of file ScalarEvolution.cpp. References C, get(), llvm::ConstantSInt::get(), llvm::ConstantFP::get(), llvm::ConstantExpr::getCast(), llvm::Constant::getNullValue(), llvm::Type::getSignedVersion(), llvm::Type::isFloatingPoint(), and llvm::Type::isSigned(). Referenced by llvm::SCEVAddRecExpr::evaluateAtIteration(), llvm::SCEVAddExpr::get(), getNegativeSCEV(), llvm::SCEVAddRecExpr::getNumIterationsInRange(), and PartialFact(). |
|
getType - Return the LLVM type of this SCEV expression. Implements llvm::SCEV. Definition at line 322 of file ScalarEvolution.cpp. References llvm::Value::getType(). |
|
Definition at line 416 of file ScalarEvolutionExpressions.h. |
|
hasComputableLoopEvolution - Return true if this SCEV changes value in a known way in the specified loop. This property being true implies that the value is variant in the loop AND that we can emit an expression to compute the value of the expression at any particular loop iteration. Implements llvm::SCEV. Definition at line 419 of file ScalarEvolutionExpressions.h. |
|
isLoopInvariant - Return true if the value of this SCEV is unchanging in the specified loop. Implements llvm::SCEV. Definition at line 314 of file ScalarEvolution.cpp. References llvm::Loop::contains(), and I. |
|
print - Print out the internal representation of this scalar to the specified stream. This should really only be used for debugging purposes. Implements llvm::SCEV. Definition at line 326 of file ScalarEvolution.cpp. References llvm::WriteAsOperand(). |
