* math: Decompose math-use-builtins.hAdhemerval Zanella2020-06-221-45/+11
| | | | | | | | | | | Each symbol definitions are moved on a separated file and it cover all symbol type definitions (float, double, long double, and float128). It allows to set support for architectures without the boiler place of copying default values. Checked with a build on the affected ABIs.

* Use GCC builtins for copysign functions if desired.Stefan Liebler2019-12-111-0/+9
| | | | | | | | | | | | This patch is always using the corresponding GCC builtin for copysignf, copysign, and is using the builtin for copysignl, copysignf128 if the USE_FUNCTION_BUILTIN macros are defined to one in math-use-builtins.h. Altough the long double version is enabled by default we still need the macro and the alternative implementation as the _Float128 version of the builtin is not available with all supported GCC versions.

* Use GCC builtins for round functions if desired.Stefan Liebler2019-12-111-0/+5
| | | | | | | | | | | | This patch is using the corresponding GCC builtin for roundf, round, roundl and roundf128 if the USE_FUNCTION_BUILTIN macros are defined to one in math-use-builtins.h. This is the case for s390 if build with at least --march=z196 --mzarch. Otherwise the generic implementation is used. The code of the generic implementation is not changed.
