--- Comment #11 from Gabriel F. T. Gomes <gftg at linux dot vnet.ibm.com> ---
For iszero, I could write a patch similar to the one I wrote (and that is still
under review) for issignaling
(https://sourceware.org/ml/libc-alpha/2017-08/msg00859.html). That would make
iszero use the correct __fpclassify* function for each type, instead of relying
on the type-generic fpclassify macro.
Does that sound like a good approach for this problem?
