2005-12-08 Steven Munroe <sjmunroe@us.ibm.com>
Tom Gall <tom_gall@vnet.ibm.com> * elf/rtld.c (dl_main): Initialize l_local_scope for sysinfo_map. * sysdeps/powerpc/elf/libc-start.c: Move this... * sysdeps/unix/sysv/linux/powerpc/libc-start.c: ...to here. * sysdeps/powerpc/powerpc32/dl-start.S: Add _dl_main_dispatch label. * sysdeps/powerpc/powerpc32/hp-timing.h: New file. * sysdeps/unix/sysv/linux/powerpc/Versions: New file. * sysdeps/unix/sysv/linux/clock_getres.c: If HAVE_CLOCK_GETRES_VSYSCALL is not defined, redefine INTERNAL_VSYSCALL and INLINE_VSYSCALL to INTERNAL_SYSCALL and INLINE_SYSCALL respectively. Otherwise include <bits/libc-vdso.h>. Use INLINE_VSYSCALL and INTERNAL_SYSCALL instead of the normal versions throughout the code. * sysdeps/unix/sysv/linux/clock_gettime.c: Likewise if HAVE_CLOCK_GETTIME_VSYSCALL is defined. * sysdeps/unix/sysv/linux/powerpc/bits/libc-vdso.h: New file. * sysdeps/unix/sysv/linux/powerpc/dl-vdso.c: New file. * sysdeps/unix/sysv/linux/powerpc/dl-vdso.h: New file. * sysdeps/unix/sysv/linux/powerpc/get_clockfreq.c: Use vDSO. * sysdeps/unix/sysv/linux/powerpc/gettimeofday.c: New file. * sysdeps/unix/sysv/linux/powerpc/Makefile: Add dl-vdso to routines. * sysdeps/unix/sysv/linux/powerpc/powerpc32/sysdep.h: Define INLINE_VSYSCALL, INTERNAL_VSYSCALL, INTERNAL_SYSCALL_NCS, INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK, HAVE_CLOCK_GETRES_VSYSCALL, and HAVE_CLOCK_GETTIME_VSYSCALL. * sysdeps/unix/sysv/linux/powerpc/powerpc64/sysdep.h: Likewise.
