Wx64

Write val to low 64 bits of a ZMM register; upper bits are preserved.

Signature

(wx64 reg val x86) → x86

Definitions and Theorems

Function: wx64$inline

(defun wx64$inline (reg val x86)
  (declare (xargs :stobjs (x86)))
  (declare (type (unsigned-byte 4) reg)
           (type (unsigned-byte 64) val))
  (wz64 reg val x86 :regtype 1))
