Hi Jakub, > This doesn't seem to handle the powerpc* IBM double double long double.
Do we support the IEEE Fortran modules on this target, despite having a non-IEEE long double? I remember we talked about it when I first implemented it, but can’t remember what choice we ended up making. > __LDBL_IS_IEC_60559__ isn't defined for this type, because it is far from > an IEEE754 type, but it has signaling NaNs - as can be seen in glibc > libc/sysdeps/ieee754/ldbl-128ibm/s_issignalingl.c > the type is a pair of doubles and whether it is a sNaN or qNaN is determined > by whether the first double is a sNaN or qNaN. > > Ok for trunk? It doesn’t hurt to provide an implementation, in any case. OK to push, and thanks for the patch. FX
