You can also make your own functions skippable by default with either the `[[gnu::artificial]]` or (the newer and more generalized) `[[gnu::nodebug]]` in GCC and Clang.
For lldb, checkout the `sif` command. It lets you step into a specific function by name. If the current line is `doFunStuff(a(), b())`, and I want to step past the a and b functions, then I can step into doFunStuff by running `sif Fun`. You could type in the whole name but it works matches by substring.
