Shift Left and Add Pointer InstructionShift Left and Add Pointer Instructionshladdp4
Instruction Type M
Format
(qp) shladdp4 r1 = r2, count2, r3
Description
The first source operand is shifted to the left by count2 bits and then is added to the second source operand. The upper 32 bits of the result are forced to zero, and then bits {31:30} of GR r3 are copied to bits {62:61} of the result. This result is placed in GR r1. The first operand can be shifted by 1, 2, 3, or 4 bits.
