get method - This just gets and returns a new SCEVZeroExtend object Definition at line 539 of file ScalarEvolution.cpp. References llvm::SCEVUnknown::get(), and llvm::ConstantExpr::getCast(). Referenced by getTruncateOrZeroExtend(). |
|
Definition at line 120 of file ScalarEvolutionExpressions.h. Referenced by getValueRange(). |
|
getType - Return the LLVM type of this SCEV expression. Implements llvm::SCEV. Definition at line 121 of file ScalarEvolutionExpressions.h. Referenced by getValueRange(). |
|
getValueRange - Return the tightest constant bounds that this value is known to have. This method is only valid on integer SCEV objects. Reimplemented from llvm::SCEV. Definition at line 233 of file ScalarEvolution.cpp. References getOperand(), and getType(). |
|
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 127 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 123 of file ScalarEvolutionExpressions.h. |
|
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 237 of file ScalarEvolution.cpp. |
