the question then becomes whether GCC is helped or harmed by
its current policy of unpredictable excess precision.
it's quite unfortunate that gcc responders feel so free to vent
their annoyance about this. Pinski, for instance, is absurdly
unhelpful in suggesting that the bug reporter just abandon x87.
again, the problem is well-understood: the lack of predictability of
when excess precision is retained by x87. the problem is not EP or x87.
the only constructive comment in this thread so far has been that libm
might somehow rely on EP (ie can't use the _FPU_SET_CW workaround).
which code is this? I'd guess it might be related to using series
approximations, and the code could either set CW or accept 64b results.
