namespace  llvm
 This is an optimization pass for GlobalISel generic memory operations.


unsigned llvm::getICmpCode (CmpInst::Predicate Pred)
 Encode a icmp predicate into a three bit mask.
Constantllvm::getPredForICmpCode (unsigned Code, bool Sign, Type *OpTy, CmpInst::Predicate &Pred)
 This is the complement of getICmpCode.
bool llvm::predicatesFoldable (CmpInst::Predicate P1, CmpInst::Predicate P2)
 Return true if both predicates match sign or if at least one of them is an equality comparison (which is signless).
unsigned llvm::getFCmpCode (CmpInst::Predicate CC)
 Similar to getICmpCode but for FCmpInst.
Constantllvm::getPredForFCmpCode (unsigned Code, Type *OpTy, CmpInst::Predicate &Pred)
 This is the complement of getFCmpCode.
bool llvm::decomposeBitTestICmp (Value *LHS, Value *RHS, CmpInst::Predicate &Pred, Value *&X, APInt &Mask, bool LookThroughTrunc=true)
 Decompose an icmp into the form ((X & Mask) pred 0) if possible.
