I just finished stepping through some code having to do with PCs in simple CPU, and I noticed that not printing DPRINTFs is actually a fairly involved process, considering that you're not actually doing anything. Part of the issue, I think, is that whether or not a traceflag is on is stored in a vector of Bools. Since the size of the vector won't change often (ever?) would it make sense to just make it a char [] and use something like the following?
flags[t >> 3] & (1 << (t & 3)); I realize when you've got tracing on you're not going for blazing speed in the first place, but if it's easy to tighten it up a bit that's probably a good idea. The other possibility is that it's actually not doing a whole lot but calling through a bunch of functions gdb stops at one at a time. That would look like a lot of work to someone stepping through with gdb but could be just as fast.
