Method Detail

getRegisterSize

public static AVXKind.AVXSize getRegisterSize(Value a)

getDataSize

public static AVXKind.AVXSize getDataSize(AMD64Kind kind)

getRegisterSize

public static AVXKind.AVXSize getRegisterSize(AMD64Kind kind)

changeSize

public static AMD64Kind changeSize(AMD64Kind kind,
                                   AVXKind.AVXSize newSize)

getMaskKind

public static AMD64Kind getMaskKind(AMD64Kind kind)

getAVXKind

public static AMD64Kind getAVXKind(AMD64Kind base,
                                   AVXKind.AVXSize size)

getAVXKind

public static AMD64Kind getAVXKind(AMD64Kind base,
                                   int length)

Returns the smallest kind that is able to hold a value of the specified base and vector length. When a length is specified that results a total data size that is not an exact match for a kind, the smallest kind that can hold the specified value will be returned. As an example, if a base kind of DWORD and a length of 3 is specified the function will return V128_DWORD since it is the smallest kind (4 x DWORD) that can hold the requested data. Calling this function with a length that exceeds the largest supported register is an error.

Parameters:

base - the kind of each element of the vector

length - the length of the vector

Returns:

the kind representing the smallest vector register that can hold the requested data
