[hatari-devel] New DSP trace functions added

[Laurent Sallafranque]

Hi,

I've added 2 new functions to dsp_disasm :

dsp_disasm_reg : this shows the state of the concerned register before 
and after the execution of the instruction
dsp_disasm_mem : this shows the state of the concerned memory address 
before and after the execution of the instruction

Both of them are working only with dsp_disasm.

(It would make no sense to display a register or memory change without 
knowing which instruction was executed).

I've tried to optimize it to have no slowness with the 3 dsp_disasm_xxx 
functions activated when DSP doesn't do anything.

Regards

Laurent
