As noted in bug 21607, NO_LONG_DOUBLE conditionals in libm tests are no longer effective. For most this is harmless - they were only present because of long double functions not being declared with _LIBC defined, and _LIBC is no longer defined for building most tests. For the few where this is actually relevant to the test, testing LDBL_MANT_DIG > DBL_MANT_DIG is more appropriate as that limits the test to public APIs. This patch fixes the tests accordingly. Tested for x86_64 and arm. [BZ #21607] * math/basic-test.c [!NO_LONG_DOUBLE]: Change conditionals to [LDBL_MANT_DIG > DBL_MANT_DIG]. * math/bug-nextafter.c [!NO_LONG_DOUBLE]: Remove conditionals. * math/bug-nexttoward.c [!NO_LONG_DOUBLE]: Likewise. * math/test-math-isinff.cc [!NO_LONG_DOUBLE]: Likewise. * math/test-math-iszero.cc [!NO_LONG_DOUBLE]: Likewise. * math/test-nan-overflow.c [!NO_LONG_DOUBLE]: Likewise. * math/test-nan-payload.c [!NO_LONG_DOUBLE]: Likewise. * math/test-nearbyint-except-2.c [!NO_LONG_DOUBLE]: Likewise. * math/test-nearbyint-except.c [!NO_LONG_DOUBLE]: Likewise. * math/test-powl.c [!NO_LONG_DOUBLE]: Likewise. * math/test-signgam-finite-c99.c [!NO_LONG_DOUBLE]: Likewise. * math/test-signgam-finite.c [!NO_LONG_DOUBLE]: Likewise. * math/test-signgam-main.c [!NO_LONG_DOUBLE]: Likewise. * math/test-snan.c [!NO_LONG_DOUBLE]: Likewise. * math/test-tgmath-ret.c [!NO_LONG_DOUBLE]: Likewise. * math/test-tgmath.c: Include <float.h>. [!NO_LONG_DOUBLE]: Change conditionals to [LDBL_MANT_DIG > DBL_MANT_DIG]. * math/test-tgmath2.c: Include <float.h>. [!NO_LONG_DOUBLE]: Change conditionals to [LDBL_MANT_DIG > DBL_MANT_DIG].
