* sysdeps/ieee754/ldbl-128ibm/s_nextafterl.c (__nextafterl): Use math_opt_barrier and math_force_eval macros. 2007-03-27 Jakub Jelinek <jakub@redhat.com> [BZ #3306] * math/math_private.h (math_opt_barrier, math_force_eval): Define. * sysdeps/i386/fpu/math_private.h: New file. * sysdeps/x86_64/fpu/math_private.h: New file. * math/s_nexttowardf.c (__nexttowardf): Use math_opt_barrier and math_force_eval macros. Use "+m" constraint on asm rather than "=m" and "m". * math/s_nextafter.c (__nextafter): Likewise. * sysdeps/ieee754/ldbl-128ibm/s_nexttoward.c (__nexttoward): Likewise. * sysdeps/ieee754/flt-32/s_nextafterf.c (__nextafterf): Likewise. * sysdeps/ieee754/ldbl-128/s_nexttoward.c (__nexttoward): Likewise. * sysdeps/ieee754/ldbl-96/s_nexttoward.c (__nexttoward): Likewise. * sysdeps/i386/fpu/s_nextafterl.c (__nextafterl): Use math_opt_barrier and math_force_eval macros. * sysdeps/ieee754/ldbl-128/s_nextafterl.c (__nextafterl): Likewise. * sysdeps/ieee754/ldbl-96/s_nextafterl.c (__nextafterl): Likewise. * sysdeps/i386/fpu/s_nexttoward.c: Include float.h. (__nexttoward): Use math_opt_barrier and math_force_eval macros. Use "+m" constraint on asm rather than "=m" and "m". Only use asm to force double result if FLT_EVAL_METHOD is 2. * sysdeps/i386/fpu/s_nexttowardf.c: Include float.h. (__nexttowardf): Use math_opt_barrier and math_force_eval macros. Use "+m" constraint on asm rather than "=m" and "m". Only use asm to force double result if FLT_EVAL_METHOD is not 0. * sysdeps/ieee754/ldbl-128ibm/s_nexttowardf.c: Include float.h. (__nexttowardf): Use math_opt_barrier and math_force_eval macros. If FLT_EVAL_METHOD is not 0, force x to float using asm. * sysdeps/ieee754/ldbl-opt/s_nexttowardfd.c: Include float.h. (__nldbl_nexttowardf): Use math_opt_barrier and math_force_eval macros. If FLT_EVAL_METHOD is not 0, force x to float using asm. * sysdeps/ieee754/ldbl-96/s_nexttowardf.c: Include float.h. (__nexttowardf): Use math_opt_barrier and math_force_eval macros. If FLT_EVAL_METHOD is not 0, force x to float using asm. * math/bug-nextafter.c (zero, inf): New variables. (main): Add new tests. * math/bug-nexttoward.c (zero, inf): New variables. (main): Add new tests.
