Move w_exp to libm-compat-call-auto
This patch adds the "_compat" suffix to the wrappers of the function exp, which use _LIB_VERSION / matherr / __kernel_standard functionality. Tested for powerpc64le, s390, and x86_64. * math/Makefile (libm-calls): Move w_exp... (libm-compat-calls-auto): Here. * math/w_expl.c: Add suffix "_compat" to filename. * sysdeps/ia64/fpu/w_expl.c: Likewise. * sysdeps/ia64/fpu/w_expf.c: Likewise. * sysdeps/ia64/fpu/w_exp.c: Likewise. * sysdeps/ieee754/dbl-64/w_exp.c: Likewise. * sysdeps/ieee754/flt-32/w_expf.c: Likewise. * sysdeps/ieee754/ldbl-128/w_expl.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/w_expl.c: Likewise. * sysdeps/ieee754/ldbl-96/w_expl.c: Likewise. * math/w_expl_compat.c: New file, copied from above. * sysdeps/ia64/fpu/w_exp_compat.c: Likewise. * sysdeps/ia64/fpu/w_expf_compat.c: Likewise. * sysdeps/ia64/fpu/w_expl_compat.c: Likewise. * sysdeps/ieee754/dbl-64/w_exp_compat.c: Likewise. * sysdeps/ieee754/flt-32/w_expf_compat.c: Likewise. * sysdeps/ieee754/ldbl-128/w_expl_compat.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/w_expl_compat.c: Likewise. * sysdeps/ieee754/ldbl-96/w_expl_compat.c: Likewise. * sysdeps/ieee754/ldbl-64-128/w_expl.c: Add suffix "_compat" to filename. * sysdeps/ieee754/ldbl-opt/w_exp.c: Likewise. * sysdeps/ieee754/ldbl-64-128/w_expl_compat.c: New file, copied from above and adjusted for the new filenames. * sysdeps/ieee754/ldbl-opt/w_exp_compat.c: Likewise.
