[patch] Can't connect to simulator that doesn't have bi-endian

[Masaki Muranaka]

Hello Daniel,

I see my patch is not reasonable.

I read man1/*-*-run.1 again and there is no description about -E.
Simulators have no responsibility to implement -E option, right?
If this is true, GDB should not expect that all simulators have -E.
(It's also possible to fix man1/run.1.)

Any comments are welcome.
