link_reloc_desc.c (712B)

      1 /* Arch-aware relocation-descriptor dispatcher.
      2  *
      3  * Stitches the per-arch slices (src/arch/<arch>/reloc.c, reached through
      4  * LinkArchDesc.reloc_desc) onto the arch-neutral table (src/obj/reloc.c).
      5  * The arch slice wins so an arch can refine the classification of an
      6  * otherwise-neutral kind (e.g. R_PLT32 is a branch on x86-64 / RISC-V but
      7  * not on AArch64) while still sharing the neutral width. */
