Classes
class	llvm::SCEVExpander
	This class uses information about analyze scalars to rewrite expressions in canonical form. More...

Namespaces
	llvm
	This class represents lattice values for constants.

Functions
bool	llvm::isSafeToExpand (const SCEV *S, ScalarEvolution &SE)
	Return true if the given expression is safe to expand in the sense that all materialized values are safe to speculate anywhere their operands are defined. More...
bool	llvm::isSafeToExpandAt (const SCEV *S, const Instruction *InsertionPoint, ScalarEvolution &SE)
	Return true if the given expression is safe to expand in the sense that all materialized values are defined and safe to speculate at the specified location and their operands are defined at this location. More...
