That's a definitive fact. ld.so for the longest time selects special DSOs to load automatically based on the data. String functions are optimized to take cache sizes into account. That info comes from cpuid as well (at least on Intel CPUs). It's crucial to get info based on the current CPU. - -- ➧ Ulrich Drepper ➧ Red Hat, Inc. ➧ 444 Castro St ➧ Mountain View, CA ❖ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) iD8DBQFGXxRf2ijCOnn/RHQRAq+aAKC/NZ5JSSEGcdt+vqnhZC40V7iJ8gCgjqjR +9Zh/jNBfg2DVb/2zh6fgUI= =8HZ1 -----END PGP SIGNATURE----- ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
