            Bug ID: 23937
           Summary: powerpc64le local ifunc IRELATIVE relocs are wrong
           Product: binutils
           Version: 2.32 (HEAD)
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ld
          Assignee: unassigned at sourceware dot org
          Reporter: amodra at gmail dot com
  Target Milestone: ---

With a brand new binutils and gcc, when I compile
gcc/testsuite/gcc.dg/attr-ifunc-4.c I see the call to magic() in main() going
via a plt stub.  There's an IRELATIVE reloc on the .iplt entry used by the
stub.  That's all as expected but
the IRELATIVE reloc points at resolver+8.  It should point at resolver+0.

As it is, when ld.so calls the resolver func r2 will have ld.so's TOC pointer
value and thus calculate the wrong offset to implementation().
