            Bug ID: 31218
           Summary: PLT rewrite doesn't work on unrelocated definition
           Product: glibc
           Version: 2.39
            Status: NEW
          Severity: normal
          Priority: P2
         Component: dynamic-link
          Assignee: unassigned at sourceware dot org
          Reporter: hjl.tools at gmail dot com
                CC: goldstein.w.n at gmail dot com
  Target Milestone: ---
            Target: x86-64

When a R_X86_64_JUMP_SLOT relocation is resolved to the unrelocated object,
PLT rewrite will write the wrong address to PLT entry if the definition in
the unrelocated object will be updated by IFUNC relocation later.
