Functions
void	llvm::convertConstantExprsToInstructions (Instruction *I, ConstantExpr *CE, SmallPtrSetImpl< Instruction * > *Insts=nullptr)
	The given instruction I contains given constant expression CE as one of its operands, possibly nested within constant expression trees.
void	llvm::convertConstantExprsToInstructions (Instruction *I, std::map< Use *, std::vector< std::vector< ConstantExpr * > > > &CEPaths, SmallPtrSetImpl< Instruction * > *Insts=nullptr)
	The given instruction I contains constant expression CE within the constant expression trees of it`s constant expression operands, and CEPaths holds all the reachable paths (to CE) from such constant expression trees of I.
void	llvm::collectConstantExprPaths (Instruction *I, ConstantExpr *CE, std::map< Use *, std::vector< std::vector< ConstantExpr * > > > &CEPaths)
	Given an instruction I which uses given constant expression CE as operand, either directly or nested within other constant expressions, return all reachable paths from the constant expression operands of I to CE, and return collected paths at CEPaths.
