Doubleword Shift Left Logical Variable |
Doubleword Shift Left Logical Variable
To execute a left-shift of a doubleword by a variable number of bits.
GPR[rd] = GPR[rt] << GPR[rs]
The 64-bit doubleword contents of GPR rt are shifted left, inserting zeros into the emptied bits; the result is placed in
GPR rd. The bit-shift amount in the range 0 to 63 is specified by the low-order 6 bits in GPR rs.
s = GPR[rs]5..0 GPR[rd] = GPR[rt](63-s)..0 || 0s
