|
getType - Return the LLVM type of this SCEV expression. Implements llvm::SCEV. Definition at line 137 of file ScalarEvolution.cpp. |
|
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 142 of file ScalarEvolution.cpp. |
|
isLoopInvariant - Return true if the value of this SCEV is unchanging in the specified loop. Implements llvm::SCEV. Definition at line 132 of file ScalarEvolution.cpp. |
|
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 147 of file ScalarEvolution.cpp. |
