properly, so go back to unflagging them all before processing any via1
interrupts. Perhaps this can be changed back when we get ADB code that
does not rely on the ROMs?
it into three pieces:
* locore.S, which contains generic mips locore code,
applicable for both r2000/r3000 and r4000s (in 32-bit mode).
* locore_r2000.S, which contains r2000/r3000 (MIPS-I) versions
of the locore functions that need mips-generation-specific
instructions or handling.
* locore_r4000.S, which contains r4000/r4400/r4600 (MIPS-III?) versions
of the locore functions that need mips-generation-specific
instructions or handling.
Much of the code in locore_r4000.S is derived from Per Fogelstrom's Pica port.
locore.S still contains some pmax-specific DMA-buffer copy functions.
to the mips tree.
* Add declarations of functions used by vm_machdep.c.
* Add declarations of functions printed by name in stack tracebacks.
* Add declarations of functions used by the model-independnet mips machdep.c
code.
symbolic lookup of the CPU-level specific locore entry points to use the
r2k, not the r4k, labels.
Include header files to get prototyped declarations of ipintr() and arpintr().
Remove unused variables and parenthesize assignments in if () expressions.
Gcc warns of a possible && vs || operator-precedence bug in the network
softint dispatch code, which needs more thought.
interrupts only after the condition that caused the interrupt has been
cleared. This is a particular problem with the 5380 SCSI controller,
since the Mac glue logic may raise (e.g.) the SCSI DRQ interrupt a number
of times during the course of a normal transfer. By waiting to unflag it,
we effectively ignore all but the first.
