03-reloc-annotations.sh (887B)

      1 # Golden: relocation records + inline disasm annotation for an rv64
      2 # call site. Asserts the auipc/jalr pair carries the symbol annotation
      3 # AND the relocation table prints the ELF-canonical kind name
      4 # (R_RISCV_CALL, via the per-arch ObjElfArchOps.reloc_name table — matching
      5 # binutils objdump). The inline disasm annotation keeps the arch-neutral
      6 # spelling ([RV_CALL]); it comes from the disassembler, not the obj reader.
