            Bug ID: 105210
           Summary: gcc/auto-profile.cc:391:11: warning: variable 'level'
                    set but not used
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dcb314 at hotmail dot com
  Target Milestone: ---

A compile of recent gcc trunk with clang trunk shows
that local variable level is set but not used.

$ fgrep level ../trunk.git/gcc/auto-profile.cc
          level information (not source level). This info is used to help
     This will be enforced when instruction-level discriminator
        function is a top-level function_instance, i.e. it is the original =
copy
  /* For a given DECL, returns the top-level function_instance.  */
      int level =3D 0;
          level++;
/* For a given DECL, returns the top-level function_instance.  */
$=20

Suggest remove local variable.=
