checkTensorElementType()

static LogicalResult checkTensorElementType ( function_ref< InFlightDiagnostic()>  emitError, Type  elementType  )

static

Definition at line 312 of file BuiltinTypes.cpp.

References mlir::emitError(), and mlir::TensorType::isValidElementType().

extractStrides()

static LogicalResult extractStrides ( AffineExpr  e, AffineExpr  multiplicativeFactor, MutableArrayRef< AffineExpr >  strides, AffineExpr &  offset  )

static

Takes a single AffineExpr e and populates the strides array with the strides expressions for each dim position.

The convention is that the strides for dimensions d0, .. dn appear in order to make indexing intuitive into the result.

extractStridesFromTerm()

static void extractStridesFromTerm ( AffineExpr  e, AffineExpr  multiplicativeFactor, MutableArrayRef< AffineExpr >  strides, AffineExpr &  offset  )

static

getStridesAndOffset()

static LogicalResult getStridesAndOffset ( MemRefType  t, SmallVectorImpl< AffineExpr > &  strides, AffineExpr &  offset  )

static

A stride specification is a list of integer values that are either static or dynamic (encoded with ShapedType::kDynamic).

Strides encode the distance in the number of elements between successive entries along a particular dimension.

For example, memref<42x16xf32, (64 * d0 + d1)> specifies a view into a non-contiguous memory region of 42 by 16 f32 elements in which the distance between two consecutive elements along the outer dimension is 1 and the distance between two consecutive elements along the inner dimension is 64.

The convention is that the strides for dimensions d0, .. dn appear in order to make indexing intuitive into the result.
