            Bug ID: 69084
           Summary: lra-remat.c:165: dead function ?
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dcb314 at hotmail dot com
  Target Milestone: ---

From a trial build of gcc with clang++

../../src/trunk/gcc/lra-remat.c:165:1: warning: function 'rtx_hash' is not
needed and will not be emitted [-Wunneeded-internal-declaration]

It seems that rtx_hash is recursive and so gcc doesn't notice it
is only called by itself.

Suggest delete unused function.
