* Provide a C++ version of issignaling that does not use __MATH_TGGabriel F. T. Gomes2017-08-221-0/+113
The macro __MATH_TG contains the logic to select between long double and _Float128, when these types are ABI-distinct. This logic relies on __builtin_types_compatible_p, which is not available in C++ mode. On the other hand, C++ function overloading provides the means to distinguish between the floating-point types. The overloading resolution will match the correct parameter regardless of type qualifiers, i.e.: const and volatile. Tested for powerpc64le, s390x, and x86_64. * math/math.h [defined __cplusplus] (issignaling): Provide a C++ definition for issignaling that does not rely on __MATH_TG, since __MATH_TG uses __builtin_types_compatible_p, which is only available in C mode. (CFLAGS-test-math-issignaling.cc): New variable. * math/Makefile [CXX] (tests): Add test-math-issignaling. * math/test-math-issignaling.cc: New test for C++ implementation of type-generic issignaling. * sysdeps/powerpc/powerpc64le/Makefile [subdir == math] (CXXFLAGS-test-math-issignaling.cc): Add -mfloat128 to the build options of test-math-issignaling on powerpc64le.
