mlirIntegerSetEqual()

MLIR_CAPI_EXPORTED bool mlirIntegerSetEqual	(	MlirIntegerSet	s1,
		MlirIntegerSet	s2 )

Checks if two integer set objects are equal.

This is a "shallow" comparison of two objects. Only the sets with some small number of constraints are uniqued and compare equal here. Set objects that represent the same integer set with different constraints may be considered non-equal by this check. Set difference followed by an (expensive) emptiness check should be used to check equivalence of the underlying integer sets.

Prints an integer set by sending chunks of the string representation and forwarding userData to callback`.

/ Gets or creates a new integer set in the given context. The set is defined / by a list of affine constraints, with the given number of input dimensions / and symbols, which are treated as either equalities (eqFlags is 1) or / inequalities (eqFlags is 0).
