SETRACE Report Generator

Hi All

Here is a small program that uses the SETRACE instruction to collect data on cog activity.
I've been using it on the FPGA to test stuff and get a clearer picture on P2's inner workings.
I thought you guys might have a use for it too.

For separate cog variant:
Just set up the pin exchange function and SET pin 127 to start trace.
To stop trace CLEAR pin 127 and the results will be transmitted.

For single cog variant:
SETXFR #n
exec code..
SETXFR #0
CALL #report

The Rnnn represents the record number
Tn is the task number
+nn is the cycle count from the last execution of that task
ZC represent Z/C flags
S indicates pipeline stall
F indicates condition false
X indicates a cancelled operation
$nnn is the tasks program counter (indented)

Here's a sample output 
r000 t3 +01       ____ ____ ____ $033
r001 t0 +02       $00f ____ ____ ____
r002 t0 +01       $010 ____ ____ ____
r003 t0 +01   s   $011 ____ ____ ____
r004 t0 +01   s   $011 ____ ____ ____
r005 t0 +01   s   $011 ____ ____ ____
r006 t0 +01   s   $011 ____ ____ ____
r007 t0 +01       $011 ____ ____ ____
r008 t2 +09       ____ ____ $02d ____
r009 t0 +02       $012 ____ ____ ____
r010 t1 +11       ____ $028 ____ ____
r011 t0 +02    fx $013 ____ ____ ____
r012 t0 +01    fx $014 ____ ____ ____
r013 t2 +05       ____ ____ $02d ____
r014 t3 +14       ____ ____ ____ $030
r015 t0 +03       $012 ____ ____ ____

It' was designed for DE2-115 only :( (Apologies to DE0 users,but you need a separate cog)

Edit: Added single COG variant

    Nice work Brian. IIRC the pin xfr mode to aux can run in the background, so perhaps this is doable on the DE0 to some extent?

    Thank you!

    With all the changes, little snippets are a big help. Much appreciated. We should start a pile of these somewhere... I've kind of lost track of all the code we've got sitting around. Some of it's old, but still valuable at this point.

    Ray,
    Just posted a variant that runs in the same COG as the test code.
    So full steam ahead for DE0 too. :)

    Excellent!
    Have my P2 Debugger semi working - had to replace the tx bit-banging with SENDSER as waitcnt is not working. Now have to replace the receive end.

    Is the wait x broken too? Maybe that is why the serial version of Chip's balls demo isn't working?

    WAITX checks out OK
    In the sample output in post #1 the $11 address in task0 is a WAIT 5 instruction that stalls the pipeline. :)

    My LMM execution unit is working nicely on the latest DE0 code. I have replaced th tx and rx to use the serial uart. I now only need to mod the disassembler for the new instruction set.
