Split helper classification macros from mathcalls.h
The classification macros: finite, fpclassify, iseqsig, isinf, isnan,
issignaling, and signbit are defined by ISO C11 and declared in
mathcalls.h for each of the floating-point types: float, double, and
long double.
TS 18661-3 does not mention these macros for float128, however support
for them must be present when _Float128 is present. This is true,
even when the feature test macro __STDC_WANT_IEC_60559_TYPES_EXT__ is
false. Other function declarations in mathcalls.h, on the other hand,
depend on __STDC_WANT_IEC_60559_TYPES_EXT__.
This patch splits the helper functions (__finite, __fpclassify,
__iseqsig, __isinf, __isnan, __issignaling, and __signbit) from
mathcalls.h, so that these helper functions can be declared for
_Float128, even when __STDC_WANT_IEC_60559_TYPES_EXT__ is false.
Tested for powerpc64le, s390x, and x86_64.
* include/bits/mathcalls-helper-functions.h: New file.
* math/Makefile (headers): Add bits/mathcalls-helper-functions.h.
* math/bits/mathcalls.h (__finite, __fpclassify, __iseqsig)
(__isinf, __isnan, __issignaling, __signbit): Move declarations to
math/bits/mathcalls-helper-functions.h.
* math/bits/mathcalls-helper-functions.h: New file.
* math/math.h: Include bits/mathcalls-helper-functions.h for
float, double, and long double.
