◆ copyAPIntToArrayForBEmachine()

static void copyAPIntToArrayForBEmachine ( APInt  value,
size_t  numBytes,
char *  result 
)
static

Copy actual numBytes data from value (APInt) to char array(result) for BE format.

Definition at line 475 of file BuiltinAttributes.cpp.

Referenced by writeBits().

◆ copyArrayToAPIntForBEmachine()

static void copyArrayToAPIntForBEmachine ( const char *  inArray,
size_t  numBytes,
APInt &  result 
)
static

Copy numBytes data from inArray(char array) to result(APINT) for BE format.

Referenced by readBits().

◆ dictionaryAttrSort()

template<bool inPlace>
static bool dictionaryAttrSort ( ArrayRef< NamedAttribute value,
SmallVectorImpl< NamedAttribute > &  storage 
)
static

Helper function that does either an in place sort or sorts from source array into destination.

If inPlace then storage is both the source and the destination, else value is the source and storage destination. Returns whether source was sorted.

Definition at line 60 of file BuiltinAttributes.cpp.

◆ findDuplicateElement()

static std::optional<NamedAttribute> findDuplicateElement ( ArrayRef< NamedAttribute value)
static

Returns an entry with a duplicate name from the given sorted array of named attributes.

Returns std::nullopt if all elements have unique names.

Definition at line 102 of file BuiltinAttributes.cpp.

◆ getBit()

static bool getBit ( const char *  rawData,
size_t  bitPos 
)
static

Return the value of the specified bit.

Referenced by mlir::DenseElementsAttr::BoolElementIterator::operator*(), and readBits().

◆ getDenseElementStorageWidth() [1/2]

static size_t getDenseElementStorageWidth ( size_t  origWidth)
static

Get the bitwidth of a dense element type within the buffer.

DenseElementsAttr requires bitwidths greater than 1 to be aligned by 8.

◆ getDenseElementStorageWidth() [2/2]

static size_t getDenseElementStorageWidth ( Type  elementType)
static

◆ hasSameElementsOrSplat()

template<typename Values >
static bool hasSameElementsOrSplat ( ShapedType  type,
const Values &  values 
)
static

Returns true if 'values' corresponds to a splat, i.e.

one element, or has the same element count as 'type'.

◆ isComplexOfIntType()

static bool isComplexOfIntType ( Type  type)
static

Return if the given complex type has an integer element type.

◆ isValidIntOrFloat()

static bool isValidIntOrFloat ( Type  type,
int64_t  dataEltSize,
bool  isInt,
bool  isSigned 
)
static

Check the information for a C++ data type, check if this type is valid for the current attribute.

This method is used to verify specific type invariants that the templatized 'getValues' method cannot.
