dcc6502 does not know when to stop

[wu2z]

I run dcc6502 on a 32k file and it just keeps on going and going and going, re-doing the same file over and over. I aborted it and I had over a million lines in my file.

I looked at the code and haven't figured out what is going on yet.

Try with "-o 0", this must not finish it seems:

while((pc <= 0xFFFFu) && ((pc - options.org) < byte_count)) {

@wu2z do you have the specific command line you used? Was the file exactly 32768 bytes?

$ ./dcc6502 -c -n -o 0 Super\ Mario\ Bros.\ (World).prg

        BRK             ; $7FFC Cycles: 7
        .byte $80       ; INVALID OPCODE !!!

        BEQ $7FFF       ; $7FFE Cycles: 3/4
        BRK             ; $8000 Cycles: 7

$ du -sb Super\ Mario\ Bros.\ (World).prg
32768 Super Mario Bros. (World).prg

I've found the pc variable and the loop just weird, and clearly when you need another orgin the loop never finishes.

On my first attempt using dcc6502 I used the command to > file.s... that became 4+ gb before I found this issue :)
