PowerPC -Mraw disassembly
This adds -Mraw for PowerPC objdump, a disassembler option to display
the underlying machine instruction rather than aliases. For example,
"rlwinm" always rather than "rotlwi" when the instruction is
performing a simple rotate.
binutils/
* doc/binutils.texi (objdump): Document PowerPC -M options.
gas/
* config/tc-ppc.c (md_parse_option): Reject -mraw.
include/
* opcode/ppc.h (PPC_OPCODE_RAW): Define.
(PPC_OPCODE_*): Make them all unsigned long long constants.
opcodes/
* ppc-dis.c (ppc_opts): Set PPC_OPCODE_PPC for "any" flags. Add
"raw" option.
(lookup_powerpc): Don't special case -1 dialect. Handle
PPC_OPCODE_RAW.
(print_insn_powerpc): Mask out PPC_OPCODE_ANY on first
lookup_powerpc call, pass it on second.
