* Use GCC builtins for rint functions if desired.Stefan Liebler2019-12-111-6/+11
| | | | | | | | | | | | This patch is using the corresponding GCC builtin for rintf, rint, rintl and rintf128 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.

* Always use wordsize-64 version of s_rint.c.Stefan Liebler2019-12-111-16/+16
| | | | | | | | | | This patch replaces s_rint.c in sysdeps/dbl-64 with the one in sysdeps/dbl-64/wordsize-64 and removes the latter one. The code is not changed except changes in code style. Also adjusted the include path in x86_64 file. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* Use rint functions not __rint functions in glibc libm.Joseph Myers2018-09-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the move to use, within libm, public names for libm functions that can be inlined as built-in functions on many architectures, this patch moves calls to __rint functions to call the corresponding rint names instead, with asm redirection to __rint when the calls are not inlined. The x86_64 math_private.h is removed as no longer useful after this patch. This patch is relative to a tree with my floor patch <https://sourceware.org/ml/libc-alpha/2018-09/msg00148.html> applied, and much the same considerations arise regarding possibly replacing an IFUNC call with a direct inline expansion. Tested for x86_64, and with build-many-glibcs.py. * include/math.h [!_ISOMAC && !(__FINITE_MATH_ONLY__ && __FINITE_MATH_ONLY__ > 0) && !NO_MATH_REDIRECT] (rint): Redirect using MATH_REDIRECT. * sysdeps/aarch64/fpu/s_rint.c: Define NO_MATH_REDIRECT before header inclusion. * sysdeps/aarch64/fpu/s_rintf.c: Likewise. * sysdeps/alpha/fpu/s_rint.c: Likewise. * sysdeps/alpha/fpu/s_rintf.c: Likewise. * sysdeps/i386/fpu/s_rintl.c: Likewise. * sysdeps/ieee754/dbl-64/s_rint.c: Likewise. * sysdeps/ieee754/dbl-64/wordsize-64/s_rint.c: Likewise. * sysdeps/ieee754/float128/s_rintf128.c: Likewise. * sysdeps/ieee754/flt-32/s_rintf.c: Likewise. * sysdeps/ieee754/ldbl-128/s_rintl.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_rintl.c: Likewise. * sysdeps/m68k/coldfire/fpu/s_rint.c: Likewise. * sysdeps/m68k/coldfire/fpu/s_rintf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_rint.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_rintf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_rintl.c: Likewise. * sysdeps/powerpc/fpu/s_rint.c: Likewise. * sysdeps/powerpc/fpu/s_rintf.c: Likewise. * sysdeps/riscv/rv64/rvd/s_rint.c: Likewise. * sysdeps/riscv/rvf/s_rintf.c: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_rint.c: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_rintf.c: Likewise. * sysdeps/sparc/sparc64/fpu/multiarch/s_rint.c: Likewise. * sysdeps/sparc/sparc64/fpu/multiarch/s_rintf.c: Likewise. * sysdeps/x86_64/fpu/multiarch/s_rint.c: Likewise. * sysdeps/x86_64/fpu/multiarch/s_rintf.c: Likewise. * sysdeps/x86_64/fpu/math_private.h: Remove file. * math/e_scalb.c (invalid_fn): Use rint functions instead of __rint variants. * math/e_scalbf.c (invalid_fn): Likewise. * math/e_scalbl.c (invalid_fn): Likewise. * sysdeps/ieee754/dbl-64/e_gamma_r.c (__ieee754_gamma_r): Likewise. * sysdeps/ieee754/flt-32/e_gammaf_r.c (__ieee754_gammaf_r): Likewise. * sysdeps/ieee754/k_standard.c (__kernel_standard): Likewise. * sysdeps/ieee754/k_standardl.c (__kernel_standard_l): Likewise. * sysdeps/ieee754/ldbl-128/e_gammal_r.c (__ieee754_gammal_r): Likewise. * sysdeps/ieee754/ldbl-128ibm/e_gammal_r.c (__ieee754_gammal_r): Likewise. * sysdeps/ieee754/ldbl-96/e_gammal_r.c (__ieee754_gammal_r): Likewise. * sysdeps/powerpc/powerpc32/fpu/s_llrint.c (__llrint): Likewise. * sysdeps/powerpc/powerpc32/fpu/s_llrintf.c (__llrintf): Likewise.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes more dbl-64 functions use libm_alias_double to define function aliases. Specifically, it makes the change for functions with dbl-64/wordsize-64 versions, changing both the dbl-64 and dbl-64/wordsize-64 versions and removing the ldbl-opt wrappers. Functions are excluded from this patch if there are complications because of versions of those functions also present in libc, or architecture-specific wrappers round these files. Tested for x86_64, and with build-many-glibcs.py. Installed stripped shared libraries are unchanged except for alpha (where increased use of dbl-64/wordsize-64 files, where previously ldbl-opt files that wrapped dbl-64 files were used, was expected to result in different, better code). * sysdeps/ieee754/dbl-64/s_ceil.c: Include <libm-alias-double.h>.
