TODO

- Debugger::runScript requires that a newline be present after each line in the script.
	Make this not so.
- Put SCIF printf's and trapa's in tatest and do some debugging
- Implement the FPU in assembly so we don't have to deal with C/C++'s
	automatic type conversion.  Also it ought to be faster.
- Optimize memory accesses.  Perhaps have a "TLB" that caches the host addresses of
  recently accessed SH memory.  On a per-page basis?
  	- Think about this one.  We already have a couple TLBs and adding another one
  	  probably won't speed it up.	
- Finish that FPU! Do 64-bit floats work?
	- Matrix instructions
	- Debugger commands to support double-precision stuff
- Maple bus.
- Finish the SREC loading support to make it tolerate unsuppored S types
	- Change SHCpu::go and Debugger because as it stands now each instruction is fetched twice
	  whenever the debugger prompt is used.  We don't want the debugger prompt triggering
	  exceptions.
	- When exceptions are finally implemented, things that can cause exceptions will need a
	  going over.  For example, the TMU should be able to generate interrupts, but it doesn't
	  at the moment.
- User mode stuff in general.
	- Store queues, etc
- Make the screen update itself on a regular basis better.  Currently the periodic update is a
  kludge.
- Make serial interface better.  Maybe tunnel it over TCP/IP.  Only SCIF is implemented at the
  moment...does anything use SCI?
- A GDB stub eventually, which could use that SCIF TCP/IP tunneling.
- More of the cache controller.
- GDROM syscalls
	Swirly will take in an ISO image of the data track.  No need to have an image of the audio track.
	* Should specify just how big that audio track is, perhaps through a command-line switch *
	This means that the sector numbers of the ISO image should be offset by a certain nonzero
	value.  For example, if the sector number offset is 1000, then a GDROM_CMD_READSECTORS of
	sector 1000 should actually read sector 0 of the ISO image.  Anything lower than that
	is a read to the junk audio track.

	To use ISO images we must know what the sector offset is that results from the junk audio
	track being the first session.  The default is 512 at the moment.
- Make the debugger U command work
