Reported by Reinhard Moosauer . 2000-04-10 Jes Sorensen * elf/dl-fini.c: Include alloca.h to get proper prototype for alloca(). 2000-04-11 Ulrich Drepper * test-skeleton.c (main): If STDOUT_UNBUFFERED is defined, make stdout stream unbuffered. * rt/Makefile (tests): Add tst-clock. Add rules to build tst-clock. * rt/tst-clock.c: New file. * sysdeps/unix/i386/i586/clock_getres.c: Correct expression to decide about initialization of nsec. * sysdeps/unix/i386/i586/clock_gettime.c: Correct expression to decide about initialization of freq. Set retval to zero if successful. * sysdeps/unix/sysv/linux/i386/get_clockfreq.c: Cache result. --- sysdeps/unix/sysv/linux/i386/get_clockfreq.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'sysdeps/unix/sysv/linux/i386/get_clockfreq.c') diff --git a/sysdeps/unix/sysv/linux/i386/get_clockfreq.c b/sysdeps/unix/sysv/linux/i386/get_clockfreq.c index 28f56c8fc3..65b7bb2116 100644 --- a/sysdeps/unix/sysv/linux/i386/get_clockfreq.c +++ b/sysdeps/unix/sysv/linux/i386/get_clockfreq.c @@ -29,9 +29,13 @@ __get_clockfreq (void) least one line like cpu MHz : 497.840237 We search for this line and convert the number in an integer. */ - unsigned long long int result = 0ull; + static unsigned long long int result; int fd; + /* If this function was called before, we know the result. */ + if (result != 0) + return result; + fd = open ("/proc/cpuinfo", O_RDONLY); if (__builtin_expect (fd != -1, 1)) { -- cgit 1.4.1
