[SPARC] Add LEON architecture

- Subject: [SPARC] Add LEON architecture
Hi,
this is an updated version of Konrad Eisele's patch from 2011:
http://gcc.gnu.org/ml/gcc/2011-10/msg00414.html
It defines a new LEON architecture, which is V8 with 3 additional instructions:
umac/smac a la SPARClet and casa a la V9. I don't think switching to V8+ would
be really appropriate, so LEON is essentially treated as V8 by binutils.
Tested for sparc-elf and with a patched compiler, OK for mainline?
2013-08-04 Eric Botcazou <ebotcazou@adacore.com>
Konrad Eisele <konrad@gaisler.com>
gas/
* config/tc-sparc.c (sparc_arch_types): Add leon.
(sparc_arch): Move sparc4 around and add leon.
(sparc_target_format): Document -Aleon.
* doc/c-sparc.texi: Likewise.
include/
* opcode/sparc.h (sparc_opcode_arch_val): Add SPARC_OPCODE_ARCH_LEON.
opcodes/
* sparc-dis.c (compute_arch_mask): Set SPARC_OPCODE_ARCH_LEON bit for
bfd_mach_sparc.
* sparc-opc.c (MASK_LEON): Define.
(v6, v6notlet, v7, v8, v6notv9): Add MASK_LEON.
(sparc_opc): Add leon.
(umac): Enable if MASK_LEON.
(umac): Likewise.
(casa): Likewise.
(cas): Likewise.
(casl): Likewise.
