* sysdeps/powerpc/dl-machine.c: Include dl-machine.h after the other header files. Mention about 128-byte cache line sizes. (__elf_machine_fixup_plt): Make types match elf_machine_fixup_plt. * sysdeps/powerpc/dl-machine.h (elf_machine_fixup_plt): Update for current calling sequence. * sysdeps/powerpc/dl-start.S (_dl_start_user): Close comment.
* sysdeps/powerpc/fpu/s_rint.c: Handle rounding to -0 correctly. * sysdeps/powerpc/fpu/s_rintf.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/syscalls.list: Add getrlimit and setrlimit syscalls for backwards compatibility. 2000-04-11 Geoff Keating <geoffk@cygnus.com> * sysdeps/powerpc/dl-machine.c: Include dl-machine.h after the other header files.
