Update.
2004-05-25 Steven Munroe <sjmunroe@us.ibm.com> * sysdeps/powerpc/fpu/Makefile: Make ld.so a dependency of libm.so. * sysdeps/powerpc/fpu/bits/mathinline.h [__LIBC_INERNAL_MATH_INLINES] (__ieee754_sqrt): Define as __MATH_INLINE using fsqrt instruction. (__ieee754_sqrtf): Define as __MATH_INLINE using fsqrts instruction. * sysdeps/powerpc/fpu/e_sqrt.c (__slow_ieee754_sqrt): Moved implementation from w_sqrt.c. * sysdeps/powerpc/fpu/e_sqrtf.c (__slow_ieee754_sqrtf): Moved implementation from w_sqrtf.c. * sysdeps/powerpc/fpu/w_sqrt.c (__sqrt): Wrapper implementation using inline __ieee754_sqrt(). * sysdeps/powerpc/fpu/w_sqrtf.c (__sqrtf): Wrapper implementation using inline __ieee754_sqrtf(). * sysdeps/powerpc/powerpc32/sysdep.h [__ASSEMBLER__]: Include <sysdeps/powerpc/sysdep.h> independent of __ASSEMBLER__. * sysdeps/powerpc/sysdep.h [__ASSEMBLER__] (PPC_FEATURE_*): Define PPC_FEATURE_* independent of __ASSEMBLER__. 2004-05-25 Jakub Jelinek <jakub@redhat.com> * sysdeps/pthread/aio_notify.c: Use <> instead of "" for aio_misc.h include. (aio_start_notify_thread): Define if not defined. (notify_func_wrapper): Use it. * sysdeps/pthread/aio_misc.c: Use <> instead of "" for aio_misc.h include. (aio_create_helper_thread): Define if not defined. (__aio_create_helper_thread): New function. (__aio_enqueue_request): Use aio_create_helper_thread. * nis/ypclnt.c (ypall_data, ypall_foreach): Remove. (struct ypresp_all_data): New type. (__xdr_ypresp_all): Change second argument to struct ypresp_all_data *. Replace ypall_foreach and ypall_data with objp->foreach and objp->data. (yp_all): Remove status variable, add data. Replace all uses of status with data.status. Initialize data.foreach and data.data instead of ypall_foreach and ypall_data. 2004-05-24 Jakub Jelinek <jakub@redhat.com> * elf/dl-lookup.c (add_dependency): Set DF_1_NODELETE bit in l_flags_1, not in l_flags.
