don't try to resolve addresses not contained in the elf (into some garbage) (e.g. 0x00000000)
demangle all symbols, not only functions (e.g. 0x3fc80fd8)
don't print anything if we cannot resolve it

Vollbrecht · 2024-02-12T13:35:47Z

Does it print the raw address and the decoded part (with the address again) separately? Could we do so that it either only prints a raw line or the decoded line?
You see that at the bottom output like here

It just increase the noise for no good reason i think?

mhhhh in that example you are right - looks like noise - actually the un-decoded line is the output from the target

Here it's actually needed

I could try to suppress repeating the address if the line just contains the address and nothing else

bjoernQ · 2024-02-12T14:52:27Z

It now looks like this

Much cleaner IMHO

MabezDev

This looks much clearer! I like it a lot! Ignoring addresses that don't make sense is really nice too.

Thanks!
