It's ok by me too, because it should be possible to keep the parts
relatively separate, but having command lines like --do-tracing, and so you
can use it as a multi-part tutorial where the parts are effectively
delineated by "if (clo_do_tracing) { ... }" conditions.

This > would reduce volume of output while keeping postprocessing easy. I prefer Alternative B, with the following caveat. This change (add tracing) continues to move Lackey away from its original purpose - a very simple example tool - and instead changes it into a fairly simple tool which does basic instruction set stuff - insn counts, memory access counts, IR operation counts, trace generation. That's ok by me. However: As it stands the count generation stuff is appallingly inefficient because there are way too many helper function calls. This made sense when the purpose was to be a simple example tool, but it makes operation counting run very slowly. For example, a helper function is called once per insn executed, to increment the insns-executed counter. With little effort this could be changed to be incremented by N when a straight-line sequence of N insns is run. The problem is even more acute for counting IR operations since they are more numerous than guest instructions. > --trace-extent=all,function,calltree > > Specifies whether to trace the entire program, the instructions in the > function specified by --fnname, or all instructions from entry into the > function until the function returns. The default is calltree. I understand 'all' and 'function', but not 'calltree'. You mean 'function and children' ? J |
