Use ceil functions not __ceil functions in glibc libm.
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 __ceil functions to call the corresponding ceil names instead, with asm redirection to __ceil when the calls are not inlined. Tested for x86_64, and with build-many-glibcs.py. * include/math.h [!_ISOMAC && !(__FINITE_MATH_ONLY__ && __FINITE_MATH_ONLY__ > 0) && !NO_MATH_REDIRECT] (ceil): Redirect using MATH_REDIRECT. * sysdeps/aarch64/fpu/s_ceil.c: Define NO_MATH_REDIRECT before header inclusion. * sysdeps/aarch64/fpu/s_ceilf.c: Likewise. * sysdeps/ieee754/dbl-64/s_ceil.c: Likewise. * sysdeps/ieee754/dbl-64/wordsize-64/s_ceil.c: Likewise. * sysdeps/ieee754/float128/s_ceilf128.c: Likewise. * sysdeps/ieee754/flt-32/s_ceilf.c: Likewise. * sysdeps/ieee754/ldbl-128/s_ceill.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_ceill.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_ceil_template.c: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_ceil.c: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_ceilf.c: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_ceil.c: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_ceilf.c: Likewise. * sysdeps/riscv/rv64/rvd/s_ceil.c: Likewise. * sysdeps/riscv/rvf/s_ceilf.c: Likewise. * sysdeps/sparc/sparc64/fpu/multiarch/s_ceil.c: Likewise. * sysdeps/sparc/sparc64/fpu/multiarch/s_ceilf.c: Likewise. * sysdeps/x86_64/fpu/multiarch/s_ceil.c: Likewise. * sysdeps/x86_64/fpu/multiarch/s_ceilf.c: Likewise. * sysdeps/powerpc/fpu/math_private.h [_ARCH_PWR5X] (__ceil): Remove macro. * sysdeps/ieee754/dbl-64/e_gamma_r.c (gamma_positive): Use ceil functions instead of __ceil variants. * sysdeps/ieee754/flt-32/e_gammaf_r.c (gammaf_positive): Likewise. * sysdeps/ieee754/ldbl-128/e_gammal_r.c (gammal_positive): Likewise. * sysdeps/ieee754/ldbl-128ibm/e_gammal_r.c (gammal_positive): Likewise. * sysdeps/ieee754/ldbl-128ibm/s_truncl.c (__truncl): Likewise. * sysdeps/ieee754/ldbl-96/e_gammal_r.c (gammal_positive): Likewise. * sysdeps/powerpc/power5+/fpu/s_modf.c (__modf): Likewise. * sysdeps/powerpc/power5+/fpu/s_modff.c (__modff): Likewise.
