Functions | |
static bool | llvm::isUniformLoop (Loop *Lp, Loop *OuterLp) |
static bool | llvm::isUniformLoopNest (Loop *Lp, Loop *OuterLp) |
static Type * | llvm::convertPointerToIntegerType (const DataLayout &DL, Type *Ty) |
static Type * | llvm::getWiderType (const DataLayout &DL, Type *Ty0, Type *Ty1) |
static bool | llvm::hasOutsideLoopUser (const Loop *TheLoop, Instruction *Inst, SmallPtrSetImpl< Value * > &AllowedExit) |
Check that the instruction has outside loop users and is not an identified reduction variable. | |
static bool | llvm::storeToSameAddress (ScalarEvolution *SE, StoreInst *A, StoreInst *B) |
Returns true if A and B have same pointer operands or same SCEVs addresses. | |
static bool | llvm::isTLIScalarize (const TargetLibraryInfo &TLI, const CallInst &CI) |
Checks if a function is scalarizable according to the TLI, in the sense that it should be vectorized and then expanded in multiple scalar calls. | |
