--- Comment #11 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Anyway, seems clang is buggy:
clang -O2 -m32 -mno-sse -mfpmath=387 -fexcess-precision=standard
#include <float.h>
int
main ()
{
#if FLT_EVAL_METHOD == 2 && LDBL_MANT_DIG == 64 && DBL_MANT_DIG == 53
if ((double) 191.18831051580915 == 191.18831051580915)
__builtin_abort ();
#endif
}
should always succeed, because if FLT_EVAL_METHOD is 2, it ought to be
evaluated
as (long double) (double) 191.18831051580915L == 191.18831051580915L and
(double) 191.18831051580915L is 0x1.7e606a3c65c95p+7 while
191.18831051580915L is 0x1.7e606a3c65c9503ap+7L, so they aren't equal.
