--- Comment #22 from Dmitry G. Dyachenko <dimhen at gmail dot com> ---
(In reply to Eric Botcazou from comment #21)
> What I don't get in that in comment 8 there is a command line with a PASS
> and then FAIL has "prev.cmd -march=corei7 -mtune=corei7" but the two options
> are already in the former command line...
>
> Could you post only the command line passed to cc1plus that FAILs?
