it may well be
helpful to do so, or at least to get ideas from it. It didn't add
__builtin_issignaling, but did add implementations of other related
built-in functions based on bit-manipulation, and __builtin_issignaling
would need to be implemented based on such bit-manipulation.
Apart from avoid
Hi,
In order to finalize our support for Fortran IEEE modules, we need to have
access to a reliable issignaling() macro, that would work across all
floating-point types. Some targets (glibc ones, notably) have it, but not all,
far from it. Instead of implementing our own, probably buggy,
