- Subject: [PATCH] Fix the C++ version of issignaling when __NO_LONG_DOUBLE_MATH
- is defined
- When __NO_LONG_DOUBLE_MATH is defined, __issignalingl is not available,
- thus issignaling with long double argument should call __issignaling,
- instead.
- Tested for powerpc64le.
- * math/math.h [defined __cplusplus] (issignaling): In the long
- double case, call __issignalingl only if __NO_LONG_DOUBLE_MATH
- is not defined. Call __issignaling, otherwise.
- (cherry picked from commit 3d7b66f66cb223e899a7ebc0f4c20f13e711c9e0)
- [Romain rebase on glibc 2.26]
