Ah, yes, that's indeed simpler than what I was going for (see below, incomplete).
Yours should be able to go to both 7.12 and master. Please send it to gdb-patches.
This exposes something else that needs to be done, as long
as the sim is C -- gdb/remote-sim.c:gdb_os_error (which is
what host_callback->error is set to, throws a C++ exception,
and that will want to cross the sim. But that will only work
if the sim is build with -fexceptions (which is the default
on x86_64). So we either need to always build the sim explicitly
with -fexceptions, or we need to longjmp out of the sim instead
of throwing a C++ exception. E.g., wrap calls into the sim
with TRY_SJLJ/CATCH_SJLJ and make gdb_os_error use
throw_exception_sjlj, like we handle longjmp-ing across
readline.
