  "message": "RISC-V: Add second-pass relaxation for JAL to C.J/C.JAL\n\nWhen linker relaxation converts CALL (auipc+jalr, 8 bytes) to JAL\n(4 bytes), further relaxation to C.J or C.JAL (2 bytes) may become\npossible as code shrinks and jump distances decrease.\n\nThis patch adds _bfd_riscv_relax_jal to perform this second-pass\nrelaxation.  To enable this, we introduce R_RISCV_DELETE_AND_RELAX,\na new internal relocation that combines piecewise deletion with\npreservation of relaxation capability.  When _bfd_riscv_relax_call\nrelaxes CALL to JAL, it marks the deletion as R_RISCV_DELETE_AND_RELAX\ninstead of R_RISCV_DELETE.  After the piecewise deletion is resolved,\nR_RISCV_DELETE_AND_RELAX is converted back to R_RISCV_RELAX at the\nJAL instruction offset, allowing _bfd_riscv_relax_jal to further\nrelax JAL to C.J/C.JAL.\n\nC.JAL is only available on RV32 (rd\u003dra), while C.J is available on\nboth RV32 and RV64 (rd\u003dx0).\n\nChanges since v1:\n- Use R_RISCV_DELETE_AND_RELAX with piecewise deletion instead of\n  calling _riscv_relax_delete_immediate directly, to maintain\n  relaxation performance.\n- Add preserve_relax parameter to riscv_relax_delete_bytes to\n  simplify the logic in _bfd_riscv_relax_call.\n",
