2017-10-02Do not wrap expf and exp2fSzabolcs Nagy
The new generic expf and exp2f code don't need wrappers any more, they set errno inline, so only use the wrappers on targets that need it. (If the wrapper is needed, then the top level wrapper code is included, otherwise empty w_exp*f.c is used to suppress the wrapper.) A powerpc64 expf implementation includes the expf c code directly which needed some changes. * sysdeps/ieee754/flt-32/e_exp2f.c (__exp2f): Define without wrapper. * sysdeps/ieee754/flt-32/e_expf.c (__expf): Likewise * sysdeps/ieee754/flt-32/w_exp2f.c: New file. * sysdeps/ieee754/flt-32/w_expf.c: New file. * sysdeps/powerpc/powerpc64/fpu/multiarch/e_expf-ppc64.c: Update for the new expf code. * sysdeps/powerpc/powerpc64/fpu/multiarch/w_expf.c: New file. * sysdeps/powerpc/powerpc64/power8/fpu/w_expf.c: New file. * sysdeps/m68k/m680x0/fpu/w_exp2f.c: New file. * sysdeps/m68k/m680x0/fpu/w_expf.c: New file. * sysdeps/i386/fpu/w_exp2f.c: New file. * sysdeps/i386/fpu/w_expf.c: New file. * sysdeps/i386/i686/fpu/multiarch/w_expf.c: New file. * sysdeps/x86_64/fpu/w_expf.c: New file.
2017-02-08Move w_exp to libm-compat-call-autoGabriel F. T. Gomes
This patch adds the "_compat" suffix to the wrappers of the function exp, which use _LIB_VERSION / matherr / __kernel_standard functionality. Tested for powerpc64le, s390, and x86_64. * math/Makefile (libm-calls): Move w_exp... (libm-compat-calls-auto): Here. * math/w_expl.c: Add suffix "_compat" to filename. * sysdeps/ia64/fpu/w_expl.c: Likewise. * sysdeps/ia64/fpu/w_expf.c: Likewise. * sysdeps/ia64/fpu/w_exp.c: Likewise. * sysdeps/ieee754/dbl-64/w_exp.c: Likewise. * sysdeps/ieee754/flt-32/w_expf.c: Likewise. * sysdeps/ieee754/ldbl-128/w_expl.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/w_expl.c: Likewise. * sysdeps/ieee754/ldbl-96/w_expl.c: Likewise. * math/w_expl_compat.c: New file, copied from above. * sysdeps/ia64/fpu/w_exp_compat.c: Likewise. * sysdeps/ia64/fpu/w_expf_compat.c: Likewise. * sysdeps/ia64/fpu/w_expl_compat.c: Likewise. * sysdeps/ieee754/dbl-64/w_exp_compat.c: Likewise. * sysdeps/ieee754/flt-32/w_expf_compat.c: Likewise. * sysdeps/ieee754/ldbl-128/w_expl_compat.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/w_expl_compat.c: Likewise. * sysdeps/ieee754/ldbl-96/w_expl_compat.c: Likewise. * sysdeps/ieee754/ldbl-64-128/w_expl.c: Add suffix "_compat" to filename. * sysdeps/ieee754/ldbl-opt/w_exp.c: Likewise. * sysdeps/ieee754/ldbl-64-128/w_expl_compat.c: New file, copied from above and adjusted for the new filenames. * sysdeps/ieee754/ldbl-opt/w_exp_compat.c: Likewise.
