To whom it may concern:
In general, the logic of the gcc/config/arm/linux-elf.h file dictates that if
the target is big-endian arm, gcc will use big-endian defaults (like
-mbig_endian); otherwise, gcc will use little-endian defaults. However, there
is apparently one exception to this rule.
Is there anyway for the optimizers to get at this range information still?
Or was range information removed because it is essentially impossible to use
it correctly (if so this bug report should be closed as unfixable)?
