ConstantInterval	Halide::Internal::constant_integer_bounds (const Expr &e, const Scope< ConstantInterval > &scope=Scope< ConstantInterval >::empty_scope(), std::map< Expr, ConstantInterval, ExprCompare > *cache=nullptr)
	Deduce constant integer bounds on an expression.

Detailed Description

Methods for computing compile-time constant int64_t upper and lower bounds of an expression.

Cheaper than symbolic bounds inference, and useful for things like instruction selection.
