comparing C-compiler output assembly listings

[edaverill]

I am doing pretty well at getting BC3 to ignore unimportant things when I compare listings from two compiler versions. Of course, one of the key pieces is ignoring addresses when they appear in the listing, since most any change will produce different addresses.

I have created rules for many assembly instructions that match from the opcode to the text of the instruction code. I have then told BC3 that these are "unimportant".

The problem is that I really would like to ignore mismatch if I get "ldd" on both sides, but not ignore the mismatch if I get "ldx" on one side and "ldy" on the other side.

I really want the types to be tested for match, but the contents not to be.

Is there a way to tell BC3 that I want that?

Thanks,
