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.
