Bug ID: 57800
Summary: Waste work in gfc_match_call()
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 "gfc_match_call()" in gcc/fortran/match.c, the loop on line 4189
should break immediately after "i" is set to 1. All the iterations after "i"
set to 1 do not perform any useful work, at best they just set "i" again to 1.
