Detailed Description

An alternative template-metaprogramming approach to expression matching.

Potentially more efficient. We lift the expression pattern into a type, and then use force-inlined functions to generate efficient matching and reconstruction code for any pattern. Pattern elements are either one of the classes in the namespace IRMatcher, or are non-null Exprs (represented as BaseExprNode &).

Pattern elements that are fully specified by their pattern can be built into an expression using the make method. Some patterns, such as a broadcast that matches any number of lanes, don't have enough information to recreate an Expr.

noexcept

Construct a rewriter for the given instance, which may be a pattern with concrete expressions as leaves, or just an expression.

The second optional argument (wildcard_type) is a hint as to what the type of the wildcards is likely to be. If omitted it uses the same type as the expression itself. They are not required to be this type, but the rule will only be tested for wildcards of that type when testing is enabled.

The rewriter can be used to check to see if the instance is one of some number of patterns and if so rewrite it into another form, using its operator() method. See Simplify.cpp for a bunch of example usage.

Important: Any Exprs in patterns are captured by reference, not by value, so ensure they outlive the rewriter.
