arc/nps400 : New cmem instructions and associated relocation
Add support for arc/nps400 cmem instructions, these load and store
instructions are hard-wired to access "0x57f00000 + 16-bit-offset".
Supporting this relocation required some additions to the arc relocation
handling in the bfd library, as well as the standard changes required to
add a new relocation type.
There's a test of the new instructions in the assembler, and a test of
the relocation in the linker.
bfd/ChangeLog:
* reloc.c: Add BFD_RELOC_ARC_NPS_CMEM16 entry.
* bfd-in2.h: Regenerate.
* libbfd.h: Regenerate.
* elf32-arc.c: Add 'opcode/arc.h' include.
(struct arc_relocation_data): Add symbol_name.
(arc_special_overflow_checks): New function.
(arc_do_relocation): Use arc_special_overflow_checks, reindent as
required, add an extra comment.
(elf_arc_relocate_section): Setup symbol_name in reloc_data.
gas/ChangeLog:
* testsuite/gas/arc/nps400-3.d: New file.
* testsuite/gas/arc/nps400-3.s: New file.
include/ChangeLog:
* elf/arc-reloc.def: Add ARC_NPS_CMEM16 reloc.
* opcode/arc.h (NPS_CMEM_HIGH_VALUE): Define.
ld/ChangeLog:
* testsuite/ld-arc/arc.exp: New file.
* testsuite/ld-arc/nps-1.s: New file.
* testsuite/ld-arc/nps-1a.d: New file.
* testsuite/ld-arc/nps-1b.d: New file.
* testsuite/ld-arc/nps-1b.err: New file.
opcodes/ChangeLog:
* arc-nps400-tbl.h: Add xldb, xldw, xld, xstb, xstw, and xst
instructions.
* arc-opc.c (insert_nps_cmem_uimm16): New function.
(extract_nps_cmem_uimm16): New function.
(arc_operands): Add NPS_XLDST_UIMM16 operand.
