This sounds much like d65 which I implemented back in 1994. OK, I now 
see that the last update to that was almost ten years ago, at Cameron 
Kaiser’s web page:

If I remember correctly, d65 allowed you to specify the 6502 dialect 
(documented opcodes only, some variants with some undocumented opcodes, 
and CMOS 6502 opcodes). But as far as I remember, it did not allow you 
to specify which external addresses are code and which ones are 
definitely not (for example, so that it would detect that $20 $d3 $ff 
must be data; you would not typically have jsr $ffd3 in a Commodore 
program, but instead, jsr $ffd2).
