const Type * SCEVCouldNotCompute::getType | ( | ) | const [virtual] |
getType - Return the LLVM type of this SCEV expression.
Implements llvm::SCEV.
Definition at line 139 of file ScalarEvolution.cpp.
bool SCEVCouldNotCompute::hasComputableLoopEvolution | ( | const Loop * | L | ) | const [virtual] |
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 144 of file ScalarEvolution.cpp.
bool SCEVCouldNotCompute::isLoopInvariant | ( | const Loop * | L | ) | const [virtual] |
isLoopInvariant - Return true if the value of this SCEV is unchanging in the specified loop.
Implements llvm::SCEV.
Definition at line 134 of file ScalarEvolution.cpp.
void SCEVCouldNotCompute::print | ( | std::ostream & | OS | ) | const [virtual] |
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 155 of file ScalarEvolution.cpp.
SCEVHandle SCEVCouldNotCompute::replaceSymbolicValuesWithConcrete | ( | const SCEVHandle & | Sym, | |
const SCEVHandle & | Conc | |||
) | const [virtual] |
replaceSymbolicValuesWithConcrete - If this SCEV internally references the symbolic value "Sym", construct and return a new SCEV that produces the same value, but which uses the concrete value Conc instead of the symbolic value. If this SCEV does not use the symbolic value, it returns itself.
Implements llvm::SCEV.
