getOpmask

public AllocatableValue getOpmask()

Description copied from interface: AVX512Support

Denotes the optional opmask register that allows additional masking for write operations. The Value.getValueKind() should correspond to the operand registers in such a way that all lanes may be masked (e.g. 8 bits for 512 bit QWORDs in a ZMM register). May be Value.ILLEGAL if no register should be used.

Specified by:

getOpmask in interface AVX512Support

Returns:

a register that contains the opmask operand or Value.ILLEGAL
