* [Bug fortran/57801] New: Waste work in resolve_variable() @ 2013-07-03 16:20 pchang9 at cs dot wisc.edu 2013-07-03 20:12 ` [Bug fortran/57801] Wasted " pchang9 at cs dot wisc.edu ` (2 more replies) 0 siblings, 3 replies; 4+ messages in thread From: pchang9 at cs dot wisc.edu @ 2013-07-03 16:20 UTC (permalink / raw) To: gcc-bugs http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57801 Bug ID: 57801 Summary: Waste work in resolve_variable() Product: gcc Version: 4.9.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran Assignee: unassigned at gcc dot gnu.org Reporter: pchang9 at cs dot wisc.edu CC: nistor1 at illinois dot edu The problem appears in revision 200588 in version 4.9. In method "resolve_variable()" in gcc/fortran/resolve.c, the loop on line 4908 should break immediately after "seen" is set to "true". All the iterations after "seen" set to "true" do not perform any useful work, at best they just set "seen" again to "true". ^ permalink raw reply [flat|nested] 4+ messages in thread
