Make dbl-64 atan and tan into weak aliases. This patch converts the dbl-64 implementations of atan and tan into weak aliases of __atan and __tan, in preparation for making them use libm_alias_double. Consequent changes are made to the x86_64 multiarch versions wrapping round them (with the dbl-64 functions, like other such functions, being made not to define their aliases at all if __atan or __tan are defined as macros by an including file). Tested for x86_64, and with build-many-glibcs.py. * sysdeps/ieee754/dbl-64/s_atan.c (atan): Rename to __atan and define as weak alias of __atan. Do not define any aliases if [__atan]. [NO_LONG_DOUBLE] (__atanl): Define as strong alias of __atan. [NO_LONG_DOUBLE] (atanl): Define as weak alias of __atanl. * sysdeps/ieee754/dbl-64/s_tan.c (tan): Rename to __tan and define as weak alias of __tan. Do not define any aliases if [__tan]. [NO_LONG_DOUBLE] (__tanl): Define as strong alias of __tan. [NO_LONG_DOUBLE] (tanl): Define as weak alias of __tanl. * sysdeps/x86_64/fpu/multiarch/s_atan-avx.c (atan): Rename to __atan. * sysdeps/x86_64/fpu/multiarch/s_atan-fma.c (atan): Likewise. * sysdeps/x86_64/fpu/multiarch/s_atan-fma4.c (atan): Likewise. * sysdeps/x86_64/fpu/multiarch/s_atan.c (atan): Rename to __atan and define as weak alias of __atan. * sysdeps/x86_64/fpu/multiarch/s_tan-avx.c (tan): Rename to __atan. * sysdeps/x86_64/fpu/multiarch/s_tan-fma.c (tan): Likewise. * sysdeps/x86_64/fpu/multiarch/s_tan-fma4.c (tan): Likewise. * sysdeps/x86_64/fpu/multiarch/s_tan.c (tan): Rename to __tan and define as weak alias of __tan. 2017-10-02 20:20:52 +00:00			`#define __tan __tan_avx`
