x86: Replace AddrPrefixOp0 with AddrPrefixOpReg
This patch replaces AddrPrefixOp0 with AddrPrefixOpReg to indicate that
the size of register operand is controlled by the address size prefix.
This will be used by Intel MOVDIRI and MOVDIR64B instructions later.
gas/
* config/tc-i386.c (process_suffix): Check addrprefixopreg
instead of addrprefixop0.
opcodes/
* i386-gen.c (opcode_modifiers): Replace AddrPrefixOp0 with
AddrPrefixOpReg.
* i386-opc.h (AddrPrefixOp0): Renamed to ...
(AddrPrefixOpReg): This.
(i386_opcode_modifier): Rename addrprefixop0 to addrprefixopreg.
* i386-opc.tbl: Replace AddrPrefixOp0 with AddrPrefixOpReg.
