* Remove NO_LONG_DOUBLE conditionals in libm tests (bug 21607).Joseph Myers2017-06-281-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>.

* Fix nan functions handling of payload strings (bug 16961, bug 16962).Joseph Myers2015-12-041-0/+122
The nan, nanf and nanl functions handle payload strings by doing e.g.: if (tagp[0] != '\0') { char buf[6 + strlen (tagp)]; sprintf (buf, "NAN(%s)", tagp); return strtod (buf, NULL); } This is an unbounded stack allocation based on the length of the argument. Furthermore, if the argument starts with an n-char-sequence followed by ')', that n-char-sequence is wrongly treated as significant for determining the payload of the resulting NaN, when ISO C says the call should be equivalent to strtod ("NAN", NULL), without being affected by that initial n-char-sequence. This patch fixes both those problems by using the __strtod_nan etc. functions recently factored out of strtod etc. for that purpose, with those functions being exported from libc at version GLIBC_PRIVATE. Tested for x86_64, x86, mips64 and powerpc. [BZ #16961] [BZ #16962] * math/s_nan.c (__nan): Use __strtod_nan instead of constructing a string on the stack for strtod. * math/s_nanf.c (__nanf): Use __strtof_nan instead of constructing a string on the stack for strtof. * math/s_nanl.c (__nanl): Use __strtold_nan instead of constructing a string on the stack for strtold. * stdlib/Versions (libc): Add __strtof_nan, __strtod_nan and __strtold_nan to GLIBC_PRIVATE. * math/test-nan-overflow.c: New file. * math/test-nan-payload.c: Likewise. * math/Makefile (tests): Add test-nan-overflow and test-nan-payload.
