Hi,
I kind of feel that it would make sense to also change the type of the
architecture_changed observable so the observers receive the inferior *
and the gdbarch *. It will not be used at the moment, but makes it
clearer that this observable gets triggerd for a given inferior.
WDYT?
Best,
Lancelot.
