Hi Markus,
Thanks for the patch - it works, but it introduces new failures into the gas
h8300 specific tests because it changes the default encoding for that
instruction. (To the version without the top bit set in the 4th byte). A
simpler fix is to just add a new line to the h8_opcodes table to accept the
encoding without the top bit set, but leaving in the current (top bit is set)
line. That way gas does not change its behaviour, but objdump can disassemble
both versions.
The uploaded patch does this, and it adds a new test to the gas testsuite in
order to make sure that the bug does not reoccur. I will check this patch in
along with the following changelog entry.
Cheers
Nick
