(As Stefan explained - macOS is supported. EFQ. You probably think of
Aquamacs, which AFAIU is a kind of fork of Emacs that started in the early
2000s. I don't know much more about it. They will be assimilated.)
I'd also rather use GDB because of Emacs' .gdbinit. The problem is GDB: it
supports macOS on amd64, but not on arm64 (patches welcome, says gdb-devel),
and arm64 is what I have.
So, for now, I've added 'xbacktrace' and 'pr' (safe_debug_print()) for LLDB.
Both could be useful for people investigating bugs, I think, as a bare minimum.
For anyone listening and interested:
I've looked at the GDB sources for the first time today. GDB supports arm64 on
other platforms, and it supports macOS with amd64, so it might not be too hard
to add something for someone who knows what he is doing. So far, I'm not that
someone, and I don't want to spend a ton of time on programming anyway these
days, so I won't promise to do anything.
