+       * elfnn-riscv.c (riscv_pcgp_hi_reloc): Add new field undefined_weak.
+       (riscv_record_pcgp_hi_reloc): New parameter undefined_weak.
+       Set undefined_weak field from it.
+       (relax_func_t): New parameter undefined_weak.
+       (_bfd_riscv_relax_call): New ignored parameter undefined_weak.
+       (_bfd_riscv_relax_tls_le): Likewise.
+       (_bfd_riscv_relax_align): Likewise.
+       (_bfd_riscv_relax_delete): Likewise.
+       (_bfd_riscv_relax_lui): New parameter undefined_weak.  If true,
+       allow relaxing.  For LO12* relocs, set rs1 to x0 when undefined_weak.
+       (_bfd_riscv_relax_pc): New parameter undefined_weak.  For LO12* relocs,
+       set undefined_weak from hi_reloc.  If true, allow relaxing.  For LO12*
+       relocs, set rs1 to x0 when undefined_weak and change to non-pcrel
+       reloc.
+       (_bfd_riscv_relax_section): New local undefined_weak.  Set for
+       undef weak relocs that can be relaxed.  Pass to relax_func call.
