There should be an one-to-one relationship between the assembly source and the machine instruction and indeed there is. I check the list file and find out they are indeed almost the same. The only difference is that the code section starts with 0x07 for MPASM/MPLINK and 0x05 for the gpasm/gplink. There is two word not used by MPASM/MPLINK, a bit strange. The linker scripts are exactly the same.

With an assembler there is a one-to-one relationship between a source statement and a machine instruction. A compiler must translate the high level symbolic language to a machine instructions and it has much freedom how it wants to reach the goal.
