            Bug ID: 115428
           Summary: 3 * unused in today's build
           Product: gcc
           Version: 15.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dcb314 at hotmail dot com
  Target Milestone: ---

From today's build of gcc with clang:

working $ grep Wunused /tmp/0
../../trunk/gcc/analyzer/call-summary.cc:727:21: warning: unused variable
'summary_cast_reg' [-Wunused-variable]
../../trunk/gcc/range-op.cc:209:1: warning: unused function
'has_pointer_operand_p' [-Wunused-function]
../../trunk/gcc/value-relation.cc:207:24: warning: unused variable
'relation_to_code' [-Wunused-const-variable]
working $ 

I've checked all three and they all look like candidates for deletion.

--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The reason why has_pointer_operand_p is not warned about is because it is a
`static inline` function which GCC will never warn about. Looks like clang only
warns about them if they are in a main source.

The reason why relation_to_code is not warned about is a similar reasons but
this time for `static const` variables.

See PR 52105 for that.

This one see PR 44598.

I can't figure out why GCC didn't warn about summary_cast_reg though ...
