Classes
class	llvm::InstCombiner
	The core instruction combiner logic. More...

Namespaces
	llvm
	This class represents lattice values for constants.

Macros
#define	DEBUG_TYPE   "instcombine"

Enumerations
enum	llvm::OverflowCheckFlavor {   llvm::OCF_UNSIGNED_ADD, llvm::OCF_SIGNED_ADD, llvm::OCF_UNSIGNED_SUB, llvm::OCF_SIGNED_SUB,   llvm::OCF_UNSIGNED_MUL, llvm::OCF_SIGNED_MUL, llvm::OCF_INVALID }
	Specific patterns of overflow check idioms that we match. More...

Functions
static unsigned	llvm::getComplexity (Value *V)
	Assign a complexity or rank value to LLVM Values. More...
static bool	llvm::isCanonicalPredicate (CmpInst::Predicate Pred)
	Predicate canonicalization reduces the number of patterns that need to be matched by other transforms. More...
static Value *	llvm::peekThroughBitcast (Value *V, bool OneUseOnly=false)
	Return the source operand of a potentially bitcasted value while optionally checking if it has one use. More...
static Constant *	llvm::AddOne (Constant *C)
	Add one to a Constant. More...
static Constant *	llvm::SubOne (Constant *C)
	Subtract one from a Constant. More...
static bool	llvm::IsFreeToInvert (Value *V, bool WillInvertAllUses)
	Return true if the specified value is free to invert (apply ~ to). More...
static OverflowCheckFlavor	llvm::IntrinsicIDToOverflowCheckFlavor (unsigned ID)
	Returns the OverflowCheckFlavor corresponding to a overflow_with_op intrinsic. More...
static Constant *	llvm::getSafeVectorConstantForBinop (BinaryOperator::BinaryOps Opcode, Constant *In, bool IsRHSConstant)
	Some binary operators require special handling to avoid poison and undefined behavior. More...
