------- Comment #4 from jvdelisle at gcc dot gnu dot org 2008-11-09 07:46 ------- According to the g77 documentation, system_clock uses the times(2) function.
gfortran uses either the time(2) (note no 's' on the end of the name) or the gettimeofday function. When I revise the gfortran routines to use the times(2) function I get results similar to g77. Now question is, how equivalent to g77 do we want to get in this case? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37832
