Function Documentation

◆ isScaleInExpressedTypeRange()

LogicalResult isScaleInExpressedTypeRange	(	function_ref< InFlightDiagnostic()>	emitError,
		Type	expressedType,
		double	scale )

static

Checks if the given scale value is within the valid range of the expressed type.

The expressedType argument is the floating-point type used for expressing the quantized values, and scale is the double value to check.

◆ parseAnyType()

Type parseAnyType ( DialectAsmParser & parser )

static

Parses an AnyQuantizedType.

any ::= any< storage-spec (expressed-type-spec)?> storage-spec ::= storage-type (< storage-range >)? storage-range ::= integer-literal : integer-literal storage-type ::= (i | u) integer-literal expressed-type-spec ::= : f integer-literal

◆ parseBlockSizeInfoUntilRBrace()

ParseResult parseBlockSizeInfoUntilRBrace	(	DialectAsmParser &	parser,
		SmallVectorImpl< int32_t > &	quantizedDimensions,
		SmallVectorImpl< int64_t > &	blockSizes )

static

Parses block size information for sub-channel quantization, assuming the leading '{' has already been parsed.

The block size information is provided as a comma-separated list of "Axis:BlockSize" pairs, terminated by a '}'.

The parsed axis indices are stored in quantizedDimensions, and the corresponding block sizes are stored in blockSizes.

◆ parseQuantParamListUntilRBrace()

ParseResult parseQuantParamListUntilRBrace	(	DialectAsmParser &	parser,
		Type	expressedType,
		SmallVectorImpl< double > &	scales,
		SmallVectorImpl< int64_t > &	zeroPoints,
		SmallVectorImpl< int64_t > &	dims )

static

Parses a bracketed list of quantization parameters, returning the dimensions of the parsed sub-tensors in dims.

The dimension of the list is prepended to the dimensions of the sub-tensors. This function assumes that the initial left brace has already been parsed. For example:

parseQuantParamListUntilRBrace(1.0:1, 2.0:4, 3.0:4}) -> Success, dims = [3], scales = [1.0, 2.0, 3.0], zeroPoints = [1, 4, 4]

parseQuantParamListUntilRBrace({1.0, 2.0}, {3.0:1, 4.0:9}}) -> Success, dims = [2, 2], scales = [1.0, 2.0, 3.0, 4.0], zeroPoints = [0, 0, 1, 9]

This function expects all sub-tensors to have the same rank.

◆ parseQuantParams()

ParseResult parseQuantParams	(	DialectAsmParser &	parser,
		Type	expressedType,
		double &	scale,
		int64_t &	zeroPoint )

static

Parses a quantization parameter, which is either a scale value (float) or a scale-zero point pair (float:integer).

expressedType, expressing the type of scale values, is used to validate the scale. The parsed scale and zero point (if any) are stored in scale and zeroPoint.
