2013-01-05	Implement more movem modes src	Mike Pavone

2013-01-05	Implement more address modes for movem dst and fix a missing break statement ↵	Mike Pavone
	in translate_m68k_dst
2013-01-05	FIx movem when src is reg list and dst is not a areg predec mode	Mike Pavone

2013-01-05	Fix predec address mode when used as source	Mike Pavone

2013-01-04	Fix rotate instructions that use a register source. Fix ROXL/ROXR to ↵	Mike Pavone
	actually use the appropriate x86 instruction.
2013-01-04	Add cycles for Bcc (needs work, but this changes keeps some ROMs from making ↵	Mike Pavone
	the emulator unresponsive)
2013-01-04	Don't use the native call stack for M68K calls by default	Mike Pavone

2013-01-04	Small fix for bit instructions	Mike Pavone

2013-01-03	Implement TRAP (untested)	Mike Pavone

2013-01-03	Implement MULU/MULS and DIVU/DIVS	Mike Pavone

2013-01-01	Do a sync when interrupt mask changes so we can recompute the next interrupt ↵	Mike Pavone
	cycle. Also fix a bug in which the SR part of ORI to SR was not being performed.
2012-12-31	Implement most of the "X" instructions	Mike Pavone

2012-12-30	Add support for pc indexed addressing mode to lea	Mike Pavone

2012-12-30	Support more address modes for jmp	Mike Pavone

2012-12-29	Fix swap	Mike Pavone

2012-12-29	Cleanup bit instructions and fix bug in translate_m68k_move that caused ↵	Mike Pavone
	incorrect results once translate_m68k_src was fixed
2012-12-29	Fix check in translate_m68k_src that deals with instructions for which both ↵	Mike Pavone
	operands are registers that are not mapped to a native x86-64 register
2012-12-29	Fix encoding of movsx instruction when used with new (i.e. r9-r15) ↵	Mike Pavone
	registers. This fixes the indexed addressing modes when used with a word-wide index register
2012-12-29	Some fixes for translating code in located in RAM	Mike Pavone

2012-12-29	Implement the rest of the bit instructions	Mike Pavone

2012-12-28	Fix return address pushed to stack for jsr	Mike Pavone

2012-12-28	cycles should return dst	Mike Pavone

2012-12-28	Implement pea (untested).	Mike Pavone

2012-12-28	Defer the correct address for pc relative jsr/jmp	Mike Pavone

2012-12-28	Implement scc (untested)	Mike Pavone

2012-12-28	Implement more address modes for jsr	Mike Pavone

2012-12-28	Fix areg indexed mode for move dst	Mike Pavone

2012-12-28	Implement ORI to CCR/SR	Mike Pavone

2012-12-28	Implemented move from SR	Mike Pavone

2012-12-27	Use unsigned comparisons for address decoding, exit when we hit an unhandled ↵	Mike Pavone
	addressing mode for jmp
2012-12-27	allocate a new native code chunk when we run out of space	Mike Pavone

2012-12-27	Implement areg indexed mode for lea	Mike Pavone

2012-12-27	Allow use of indexed modes as move dst	Mike Pavone

2012-12-27	Allow indexed modes to be used as a destination	Mike Pavone

2012-12-27	Fix address register indexed addressing (probably)	Mike Pavone

2012-12-27	Fix pc indexed addressing (probably) when used as a source	Mike Pavone

2012-12-27	Initial work on allowing dynamic branches and code in RAM plus a small fix ↵	Mike Pavone

2012-12-26	RTE doesn't crash the emulator anymore	Mike Pavone

2012-12-26	Initial stab at interrupt support. Make native code offsets bigger so I ↵	Mike Pavone
	don't have to worry about overflowing the offset. Implement neg and not (untested).
