Detailed Description

template<typename T>
struct MergeAffineMinMaxOp< T >

Merge an affine min/max op to its consumers if its consumer is also an affine min/max op.

This pattern requires the producer affine min/max op is bound to a dimension/symbol that is used as a standalone expression in the consumer affine op's map.

For example, a pattern like the following:

%0 = affine.min affine_map<()[s0] -> (s0 + 16, s0 * 8)> ()[sym1] %1 = affine.min affine_map<(d0)[s0] -> (s0 + 4, d0)> (%0)[sym2]

Can be turned into:

%1 = affine.min affine_map< ()[s0, s1] -> (s0 + 4, s1 + 16, s1 * 8)> ()[sym2, sym1]
