From 5fc48cd78f0c50e889d1c1f3b8f812058db71ecd Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sat, 21 Apr 2001 07:55:01 +0000 Subject: Update. 2001-04-21 Ulrich Drepper * 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. --- elf/dl-support.c | 10 ++++++++++ 1 file changed, 10 insertions(+) (limited to 'elf/dl-support.c') diff --git a/elf/dl-support.c b/elf/dl-support.c index 8c10180e26..fa1b1874e7 100644 --- a/elf/dl-support.c +++ b/elf/dl-support.c @@ -29,6 +29,7 @@ #include #include #include +#include extern char *__progname; char **_dl_argv = &__progname; /* This is checked for some error messages. */ @@ -92,6 +93,11 @@ struct r_scope_elem *_dl_main_searchlist = &_dl_initial_searchlist; /* Nonzero during startup. */ int _dl_starting_up = 1; +/* Initial value of the CPU clock. */ +#ifdef CPUCLOCK_VARDEF +CPUCLOCK_VARDEF (_dl_cpuclock_offset); +#endif + /* During the program run we must not modify the global data of loaded shared object simultanously in two threads.
