Wonder how is that possible, the patch uses REVERSE_CONDITION on GT and
that is handled by both reverse_condition and
reverse_condition_maybe_unordered.
Can I ask for preprocessed source + cc1plus command line + what -march=
etc. options one needs if it is just implied by configure, so that I can
have a look in a cross-compiler?
I really don't have access to 32-bit arm anymore.
