* Add libm_alias_*_other_r macros.Joseph Myers2017-10-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* New expf and exp2f version without SVID compat wrapperSzabolcs Nagy2017-09-251-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the expf and exp2f error handling semantics to only set errno accoring to POSIX rules. New symbol version is introduced at GLIBC_2.27. The old wrappers are kept for compat symbols. Internal calls to __expf now get the new error semantics, this seems to only affect sysdeps/i386/fpu/s_expm1f.S where the errno-only behaviour should be correct. ia64 needed assembly change to have the new and compat versioned symbol map to the same function. All linux libm abilists are updated. * math/Versions (expf): New libm symbol at GLIBC_2.27.

* Move wrappers to libm-compat-calls-autoGabriel F. T. Gomes2017-01-041-19/+0
| | | | | | | | | | This commit moves one step towards the deprecation of wrappers that use _LIB_VERSION / matherr / __kernel_standard functionality, by adding the suffix '_compat' to their filenames and adjusting Makefiles and #includes accordingly. New template wrappers that do not use such functionality will be added by future patches and will be first used by the float128 wrappers.
