commit 04deeaa9ea
Author: Lucas A. M. Magalhaes <lamm@linux.ibm.com>
Date: Fri Jul 10 19:41:06 2020 -0300
Fix time/tst-cpuclock1 intermitent failures
has 2 issues:
1. It assumes time_t == long which is false on x32.
2. tst-timespec.c is compiled without -fexcess-precision=standard which
generates incorrect results on i686 in support_timespec_check_in_range:
double ratio = (double)observed_norm / expected_norm;
return (lower_bound <= ratio && ratio <= upper_bound);
This patch does
1. Compile tst-timespec.c with -fexcess-precision=standard.
2. Replace long with time_t.
3. Replace LONG_MIN and LONG_MAX with TYPE_MINIMUM (time_t) and
TYPE_MAXIMUM (time_t).
