From 24b6515d879c992be194ccd5323b8b780fa6d4d3 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Tue, 10 Oct 2017 21:29:11 +0000 Subject: Add libm_alias_*_other_r macros. Some libm functions are unable to use the generic alias macros such as libm_alias_double because they have special symbol versioning requirements for the main float, double or long double public names. To facilitate adding _FloatN / _FloatNx function aliases in future, it's still desirable to have generic macros those functions can use as far as possible. This patch adds macros such as libm_alias_double_other, which only define names for _FloatN / _FloatNx aliases, not for float / double / long double. As present, all these new macros do nothing, but they are called in the appropriate places in macros such as libm_alias_double. This patch also arranges for lgamma implementations, and the recently added optimized float function implementations, to use the new macros to make them ready for addition of _FloatN / _FloatNx aliases. Tested for x86_64, and tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by this patch. * sysdeps/generic/libm-alias-double.h (libm_alias_double_other_r): New macro.
