None of the documents I found makes a statement as clear as the ARM EABI does.
Can someone point me to the source file where the "narrowing" is done, to maybe
simply "comment it out"?; I don't feel capable of providing a real fix, see
below, but I also don't want to rewrite large portions of my code when migrating
to GCC.
Having given more thought to the problem, isn't the "narrowing" an optimization
which should not be a fixed property of the compiler, given that even for the
same type of machine ("target") there can exist various different memory
interfaces? Hence, shouldn't it be an optimization option, "on" by default to be
backwards compatible?
