Method Detail

getASIMDKind

public static AArch64Kind getASIMDKind(AArch64Kind base,
                                       int length)

Returns the smallest ASIMD 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
