PR 20744
bfd/
* elf32-ppc.c (ppc_elf_howto_raw): Correct dst_mask on all VLE
16D relocations.
(ppc_elf_vle_split16): Correct field mask and shift for 16D relocs.
(ppc_elf_relocate_section): Correct calculation for VLE SDAREL
relocs.
ld/
* testsuite/ld-powerpc/vle-reloc-2.s: Use r6 for last insn of
each group.
* testsuite/ld-powerpc/vle-reloc-2.d: Update for above change
and sdarel reloc fix.
