EMULV() doesn't need p, hx, tx and ty if DLA_FMS is defined.
If that variables are needed for EMULV() only, GCC warns about
unused variables, like this:
../sysdeps/ieee754/dbl-64/e_sqrt.c: In function ‘__ieee754_sqrt’:
../sysdeps/ieee754/dbl-64/e_sqrt.c:56:54: warning: unused variable ‘ty’ [-Wunused-variable]
double y, t, del, res, res1, hy, z, zz, p, hx, tx, ty, s;
^
This patch fixes it for sysdeps/ieee754/dbl-64/e_sqrt.c where it happens.
* sysdeps/ieee754/dbl-64/e_sqrt.c
(__ieee754_sqrt): declare p, hx, tx and ty conditionally.
