In preparation for a gui based trace viewer, I've cleaned up the command line
version. Here's an example of single stepping
before:
gpsim> step
16c84 0x0011 0x078C addwf temp,f
read: 0x08 from temp
wrote: 0x48 to temp
wrote: 0x18 to status
cycle: 0x098063b
after:
gpsim> step
0x00000000013577FE 16c84 0x0006 0x0A0D incf x,w
read: 0x92 from x
wrote: 0x93 to W
wrote: 0x18 to status
The main difference is that the cycle is now displayed in the same line of the
instruction.
-----------------------
In addition, the trace dump command has been cleaned up too:
before:
gpsim> trace 20
read: 0x1a from status
wrote: 0x1a to status
pc: 0x0010 rrf temp,f
cycle: 0x0980639
instruction: 0x0c8c
read: 0x10 from temp
read: 0x1a from status
wrote: 0x08 to temp
wrote: 0x1a to status
pc: 0x0011 addwf temp,f
cycle: 0x098063a
instruction: 0x078c
read: 0x08 from temp
wrote: 0x48 to temp
wrote: 0x18 to status
pc: 0x0012 rrf temp,f
cycle: 0x098063b
after:
gpsim> trace 5
0x00000000013577F8 16c84 0x0015 0x1003 bcf status,0

0x00000000013577FA 16c84 0x0017 0x0008 return
0x00000000013577FC 16c84 0x0009 0x2806 goto 0x0006
0x00000000013577FE 16c84 0x0006 0x0A0D incf x,w

As you can see, the dump command looks similar to the trace after single
stepping. Furthermore, the cycle, PC, and instruction traces have been combined
into a single line. The trace information associated with the cycle appears
indented. Also notice that the trace parameter now specifies the number of
instructions instead of the number of raw trace entries.
If you have any comments or suggestions about this, let me know!
These changes are NOT in CVS because for some reason I'm unable to get access...

PS. I'm going to be at the Embedded Systems Conference in San Jose California
this week. There are some of us from the PICLIST getting together. If anybody
cares to join us, we'll be meeting at 6:30pm on Tuesday at the Byte Craft booth.
