[tremor] Tremor at 74MHz -- optimizations?

[Owen G. Emry]

First, the good news.  Tremor is alive and well on my 74MHz Cirrus board.

The rest of the news:  It's not that fast.  Depending on bitrate, it decodes 
anywhere from 1.0x real time to 1.15x (slower than) real time.  This is using 
a recent CVS version, _but_ I'm not using any configure scripts, so I'm sure 
I'm missing all sorts of optimizations.

I know the original target was realtime decode on a similar board, and I know 
Nicolas has submitted numerous improvements since then, so...

What else should I define/inline/etc. to get it sped up?  (I'm already using 
_ARM_ASSEM_ but that's all.)

Thanks in advance...

-Owen
