◆ mlirIntegerSetDump()

void mlirIntegerSetDump ( MlirIntegerSet  set)

Prints an integer set to the standard error stream.

◆ mlirIntegerSetEmptyGet()

MlirIntegerSet mlirIntegerSetEmptyGet ( MlirContext  context,
intptr_t  numDims,
intptr_t  numSymbols 
)

Gets or creates a new canonically empty integer set with the give number of dimensions and symbols in the given context.

◆ mlirIntegerSetEqual()

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.

◆ mlirIntegerSetGet()

MlirIntegerSet mlirIntegerSetGet ( MlirContext  context,
intptr_t  numDims,
intptr_t  numSymbols,
intptr_t  numConstraints,
const MlirAffineExpr *  constraints,
const bool *  eqFlags 
)

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). Both constraints and eqFlags are expected to point to at least numConstraint consecutive values.
