Description
I really do not know which project to put this in but as the bug surfaced in output from disjs (and my disassembler because I also use the videocoreiv.arch file) I am posting it here.
The videocoreiv.arch definitions used in disjs generates what I believe to be inaccurate output.
Looking at the 48 bit instructions (jump added for comparison)
1110 0000 0000 0000 uuuu uuuu uuuu uuuu uuuu uuuu uuuu uuuu "; j 0x%08x{u}"
1110 0001 0000 0000 oooo oooo oooo oooo oooo oooo oooo oooo "; b 0x%08x{$+o}"
it will display the actual target for the branch as opposed to the actual value. Perhaps a better definition (or fixup applied in code which is more cumbersome) would be
1110 0001 0000 0000 oooo oooo oooo oooo oooo oooo oooo oooo "; b 0x%08x{o} # {$+o}"
Where # is a comment character of choice.
This way if the instruction is run through an assembler it will generate the correct output however the intent/meaning is still conveyed to the reader.
Of note the 16 bit branch instructions do not apply the offset but all others do
0000 0000 010d dddd "; b r%i{d}"
0000 0000 011d dddd "; bl r%i{d}"
