The advantage(s) of incorporating the macro processor into pass 1 is/ are:

many functions do not have to be implemented twice
Functions are combined and it is not necessary to create intermediate files as output from the macro processor and input to the assembler
more flexibility is available to the programmer in which he/she may use all the features of the assembler in conjunction with macros
All of these
