* math: Add math-use-builtins-fabs (BZ#29027)Adhemerval Zanella2022-05-231-0/+1
| | | | | | | | | | | | | | | | | | Both float, double, and _Float128 are assumed to be supported (float and double already only uses builtins). Only long double is parametrized due GCC bug 29253 which prevents its usage on powerpc. It allows to remove i686, ia64, x86_64, powerpc, and sparc arch specific implementation. On ia64 it also fixes the sNAN handling: math/test-float64x-fabs math/test-ldouble-fabs Checked on x86_64-linux-gnu, i686-linux-gnu, powerpc-linux-gnu, powerpc64-linux-gnu, sparc64-linux-gnu, and ia64-linux-gnu.
* Update copyright dates with scripts/update-copyrightsPaul Eggert2022-01-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 7061 files FOO. I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah. I don't know why I run into these diagnostics whereas others evidently do not. remote: *** 912-#endif remote: *** 913: remote: *** 914- remote: *** error: lines with trailing whitespace found ... remote: *** error: sysdeps/unix/sysv/linux/statx_cp.c: trailing lines

* Use GCC builtins for roundeven functions if desired.Shen-Ta Hsieh2021-06-271-0/+1
| | | | | | | | | | | | | This patch is using the corresponding GCC builtin for roundevenf, roundeven and roundevenl if the USE_FUNCTION_BUILTIN macros are defined to one in math-use-builtins.h. These builtin functions is supported since GCC 10. The code of the generic implementation is not changed. Signed-off-by: Shen-Ta Hsieh <ibmibmibm.tw@gmail.com> Reviewed-by: H.J.

* 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.
