Peter Evans f8bda4ebd3 Remove modify_status() function
Also rewrite tests to use macros
2018-02-28 21:40:52 -06:00
Peter Evans 49199eac84 Rewrite status checks with macros
This also forces the result of operations to be considered purely as
8-bit results in _some_ cases, but not in others. We were missing some
times when an overflow is the expected behavior; because SET_RESULT()
and mos6502_modify_status() use ints, this overflow was not properly
observed.

Peter Evans 978ad1faaf Formerly "BAD" instructions are now forms of NOPs
But weird forms. In most cases they basically are NOPs, except with
different opcodes. In other cases, we call them NP2 and NP3s, and do so
because they consume 2 or 3 bytes respectively (vs. just 1 with NOP).

We had to teach some arcane magic to the emulator for this to work. We
may want to refactor to decouple the number of bytes consumed from the
address mode.

Peter Evans 90892c32e4 Add TSB (Test and Set Bits) instruction
This commit also moves the TRB code from loadstor to bits, which is
where it should have been all along.

Peter Evans 7b65dc1657 Add new BIM instruction (BIt imMediate mode)
This is not a real instruction in the 65c02 processor; I invented it for
the sole purpose of handling the specialized logic that is performed by
BIT in IMM mode. To be fair--I can imagine this really _was_ implemented
as a "separate" instruction on the chip! But I don't know that for sure.

Peter Evans 1091ec6e2a Pass image type into enc_dos; use sector_num instead of a table pointer 2018-02-20 15:36:23 -06:00
Peter Evans 98f640f0d1 Use the proper sector header length (20 bytes) 2018-02-20 14:35:07 -06:00
Peter Evans 508be6458a Pass in sector table for logical-physical orders
We were not encoding data properly, because in DOS 3.3 and ProDOS,
sectors must be interleaved on disk media (whereas in the original image
form, data is laid out in a linear fashion).

This solves a bug where we erroneously encountered a "bad" opcode (a7)
in the program code.
