- Reworked PMMU/core interface so PMMU now sees all cop 0 instructions
- Improved disassembly of PMMU instructions
- Preliminary 68LC040 support
- Fixed disassembly for EC/LC variants of '030/'040
The plan is to add the on-chip peripherals on the magicard.c driver then, when I get some consistency, hardwire it to the cpu core.
Please check this modification asap (should be fine, but I haven't compiled with a clean build)
This means that multiple changes without any execution will be seen as atomic. It also means that PULSE_LINE no longer works for signalling IRQs.
Added checks in the debug build to catch people who try to use
PULSE_LINE for non-NMI and non-RESET input lines on CPUs that no
longer support direct interrupt generation. Over time expect this
list to increase.
Before this patch a:
cpunum_set_input_line(5, ASSERT_LINE);
cpunum_set_input_line(3, ASSERT_LINE);
cpunum_set_input_line(3, CLEAR_LINE);
loses the state of line 5. This patch fixes it by adding an explicit
but optional "virtual irq line" support to the 68k interface.
Fix m68k interrupt handling by some drivers.
Clearing the NMI line to clear all the IRQ lines worked, but it just
doesn't make sense. Now that the irq lines are really independant,
the handling can be simplified.
