(qp) pshl2 r1 = r2, r3 two_byte_form, variable_form
(qp) pshl2 r1 = r2, count5 two_byte_form, fixed_form
(qp) pshl4 r1 = r2, r3 four_byte_form, variable_form
(qp) pshl4 r1 = r2, count5 four_byte_form, fixed_form
Description
The data elements of GR r2 are each independently shifted to the left by the scalar shift count in GR r3, or in the immediate field count5. The low-order bits of each element are filled with zeros. The shift count is interpreted as unsigned. Shift counts greater than 15 (for 16-bit quantities) or 31 (for 32-bit quantities) yield all zero results. The results are placed in GR r1.
