Ugh... the MOVA corner cases (_testmov2) seem to be a bit trickier.
I'm dealing with that in
right now, although it isn't yet clear to me if this is a delay slot
issue or a separate quirk.
According to the SH12 programming manual:
"If this instruction is placed immediately after a delayed branch
instruction, the PC must point to an address specified by (the
starting address of the branch destination) + 2."
Running into so many failing corner cases (in the original SH Qemu
port) was not something I anticipated. Sorry for any delays that may
I think I'll ping-pong between "for-j2-sh2-dirty-hacks " and
"feature/j2-sh2-dirty-hacks" for a while, adding support to
"feature/j2-sh2-dirty-hacks" as I go along. Any pointers are welcome.
