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