PR20744, Incorrect PowerPC VLE relocs
VLE 16A and 16D relocs were functionally swapped. PR 20744 include/ * opcode/ppc.h: Define VLE insns using 16A and 16D relocs. bfd/ * elf32-ppc.h (struct ppc_elf_params): Add vle_reloc_fixup field. * elf32-ppc.c: Include opcode/ppc.h. (ppc_elf_howto_raw): Correct dst_mask for R_PPC_VLE_LO16A, R_PPC_VLE_LO16D, R_PPC_VLE_HI16A, R_PPC_VLE_HI16D, R_PPC_VLE_HA16A, R_PPC_VLE_HA16D, R_PPC_VLE_SDAREL_LO16A, R_PPC_VLE_SDAREL_LO16D, R_PPC_VLE_SDAREL_HI16A, R_PPC_VLE_SDAREL_HI16D, R_PPC_VLE_SDAREL_HA16A, and R_PPC_VLE_SDAREL_HA16D relocs. (ppc_elf_link_hash_table_create): Update default_params init. (ppc_elf_vle_split16): Correct shift and mask. Add params. Report or fix insn/reloc mismatches. (ppc_elf_relocate_section): Pass input_section, offset and fixup to ppc_elf_vle_split16. binutils/ * NEWS: Mention PowerPC VLE relocation error. gas/ * config/tc-ppc.c: Delete VLE insn defines. (md_assemble): Swap use_a_reloc and use_d_reloc. * testsuite/gas/ppc/vle-reloc.d: Update. ld/ * emultempl/ppc32elf.em (params): Update initializer. Handle --vle-reloc-fixup command line arg.
