## Classes

class  mlir::presburger::MaybeOptimum< T >

struct  mlir::presburger::MaybeLocalRepr

## Enumerations

enum  mlir::presburger::OptimumKind { mlir::presburger::OptimumKind::Empty, mlir::presburger::OptimumKind::Unbounded, mlir::presburger::OptimumKind::Bounded }
This class represents the result of operations optimizing something subject to some constraints. More...

enum  mlir::presburger::ReprKind { mlir::presburger::ReprKind::Inequality, mlir::presburger::ReprKind::Equality, mlir::presburger::ReprKind::None }
ReprKind enum is used to set the constraint type in MaybeLocalRepr. More...

## Functions

SmallVector< int64_t, 8 > mlir::presburger::getDivUpperBound (ArrayRef< int64_t > dividend, int64_t divisor, unsigned localVarIdx)
If q is defined to be equal to expr floordiv d, this equivalent to saying that q is an integer and q is subject to the inequalities 0 <= expr - d*q <= c - 1 (quotient remainder theorem). More...

SmallVector< int64_t, 8 > mlir::presburger::getDivLowerBound (ArrayRef< int64_t > dividend, int64_t divisor, unsigned localVarIdx)

llvm::SmallBitVector mlir::presburger::getSubrangeBitVector (unsigned len, unsigned setOffset, unsigned numSet)

SmallVector< MPInt, 8 > mlir::presburger::getMPIntVec (ArrayRef< int64_t > range)
Check if the pos^th variable can be expressed as a floordiv of an affine function of other variables (where the divisor is a positive constant). More...

SmallVector< int64_t, 8 > mlir::presburger::getInt64Vec (ArrayRef< MPInt > range)
Return the given array as an array of int64_t. More...

MaybeLocalRepr mlir::presburger::computeSingleVarRepr (const IntegerRelation &cst, ArrayRef< bool > foundRepr, unsigned pos, MutableArrayRef< int64_t > dividend, unsigned &divisor)
Returns the MaybeLocalRepr struct which contains the indices of the constraints that can be expressed as a floordiv of an affine function. More...

void mlir::presburger::mergeLocalVars (IntegerRelation &relA, IntegerRelation &relB, llvm::function_ref< bool(unsigned i, unsigned j)> merge)
Given two relations, A and B, add additional local vars to the sets such that both have the union of the local vars in each set, without changing the set of points that lie in A and B. More...

int64_t mlir::presburger::gcdRange (ArrayRef< int64_t > range)
Compute the gcd of the range. More...

int64_t mlir::presburger::normalizeRange (MutableArrayRef< int64_t > range)
Divide the range by its gcd and return the gcd. More...

void mlir::presburger::normalizeDiv (MutableArrayRef< int64_t > num, int64_t &denom)
Normalize the given (numerator, denominator) pair by dividing out the common factors between them. More...

SmallVector< int64_t, 8 > mlir::presburger::getNegatedCoeffs (ArrayRef< int64_t > coeffs)
Return coeffs with all the elements negated. More...

SmallVector< int64_t, 8 > mlir::presburger::getComplementIneq (ArrayRef< int64_t > ineq)
Return the complement of the given inequality. More...
