INC.L
Operation:
D + 1 → D
Description: Increment a long-word value in a register or memory. When an operand located in memory is operated

on, the low-order 32 bits of the result are stored back to memory. The condition codes are calculated
based on the 32-bit result. Absolute addresses pointing to long elements must always be even aligned
(that is, pointing to the lowest 16 bits).
This instruction is typically used when integer data is processed.
INC.L
Prior to execution, the 36-bit A accumulator contains the value $0:0020:0000. Execution of the INC.L
instruction adds one to the A accumulator. The CCR is updated based on the result of the addition.

— Set if the extension portion of the 36-bit result is in use
— Set if the 36-bit result is unnormalized
— Set if bit 31 of the result is set
— Set if the result is zero
— Set if overflow has occurred in result
— Set if a carry occurs from bit 31 of the result
