I'd like to have some conclusion on how normal software single step
and special software single step interact. Are all the things handled
in GDB's software single step routine also the responsibility of any
stub that claims single step support?
Which is not how it works today - we let a powerpc gdbserver single
step most things, but detect atomic sequences in the client. This
avoids duplicating the logic across all stubs, but is slower.
And do these special stepping types get turned off if you disable
software single stepping manually?
