Thus my question to whoever looked at this code close enough is:
1. Is the FALLTHRU really OK?
yes, see above. Plus the fall through is only for non fp types.
Yes I see now... a quite complicated way to express the choice logic:
1. if -fcx-limited-range is set go straight for the quick overflowing
version.
2. be strict in case of ISO C99.
3. handle floaing poing divisions more precisely then multiplications
else.
2. Shouldn't the logic when to decide which kind of implementation to
take
not look a bit more like in the multiplication case?
It is the same in general anyways but division is the one that is
different between flag_complex_method==0 and flag_complex_method==1.
OK. This confirms that the three state flag_complex_method could be
eliminated, and fcx_limited_range used directly instead.
(My final goal is of course something in the way of #pragma STDC
CX_LIMITED_RANGE)...
