Update.
2001-04-21 Ulrich Drepper <drepper@redhat.com> * elf/dl-support.c: Include cpuclock-init.h. Use CPUCLOCK_VARDEF and CPUCLOCK_INIT if defined. * sysdeps/generic/dl-sysdep.c: Likewise. * sysdeps/generic/cpuclock-init.h: New file. * sysdeps/unix/i386/i586/cpuclock-init.h: New file. * sysdeps/unix/i386/i586/Versions: New file. * sysdeps/unix/i386/i586/clock_settime.c: New file. * sysdeps/unix/i386/i586/clock_gettime.c: Handle thread CPU clock separately by calling __pthread_clock_gettime if this function is available. Subtract offset from tsc value before computing time value.
