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.
