Debugger: trace address of reads and writes

[paulb-nl]

Is there a way to add the address and data of reads and writes to the tracelog? I have read through the documentation but haven't found a way to do this.

Here is an example with a 68K CPU:
move.w D0, ($2,A1) "Addr $123456, Data: $1234"

That would definitely be useful, but it'd be a big project to update all of the disassemblers.

Can’t you just use a watchpoint to add memory accesses to the trace log? For example on a Z80, this would log writes to the trace log:

wpset 0x0000,0x10000,w,1,{ tracelog "@%04X = %02X",wpaddr,wpdata ; g }

Thanks, that works. I wasn't aware that it could do that without halting execution. Maybe I read "will halt execution" in the docs and then stopped reading 😄

Well, it actually does halt, but you can immediately start execution again with a g command. Some of the examples in the documentation demonstrate this trick.
