opcode table as something that is "opened/closed".
* cgen.h (CGEN_OPCODE_DESC): New type.
(all fns): New first arg of opcode table descriptor.
(cgen_set_parse_operand_fn): Add prototype.
(cgen_current_machine,cgen_current_endian): Delete.
(CGEN_OPCODE_TABLE): New members mach,endian,operand_table,
parse_operand_fn,asm_hash_table,asm_hash_table_entries,
dis_hash_table,dis_hash_table_entries.
(opcode_open,opcode_close): Add prototypes.
* cgen.h (cgen_insn): New element `cdx'.
* i386.h (i386_optab): Add general form of aad and aam. Add ud2a
and ud2b.
(i386_regtab): Allow cr0..7, db0..7, dr0..7, tr0..7, not just
those that happen to be implemented on pentiums.
* i386.h: Change occurences of Data16 to Size16, Data32 to Size32,
IgnoreDataSize to IgnoreSize. Flag address and data size prefixes
with Size16|IgnoreSize or Size32|IgnoreSize.
* i386.h (REPNE): Rename to REPNE_PREFIX_OPCODE.
(REPE): Rename to REPE_PREFIX_OPCODE.
(i386_regtab_end): Remove.
(i386_prefixtab, i386_prefixtab_end): Remove.
(i386_optab): Use NULL as sentinel rather than "" to suit rewrite
of md_begin.
(MAX_OPCODE_SIZE): Define.
(i386_optab_end): Remove.
(sl_Suf): Define.
(sl_FP): Use sl_Suf.
* i386.h (i386_optab): Allow 16 bit displacement for `mov
mem,acc'. Combine 16 and 32 bit forms of various insns. Allow 16
bit form of ljmp. Add IsPrefix modifier to prefixes. Add addr32,
data32, dword, and adword prefixes.
(i386_regtab): Add BaseIndex modifier to valid 16 bit base/index
regs.
* i386.h (i386_regtab): Remove BaseIndex modifier from esp.
* i386.h: Allow `l' suffix on fld, fst, fstp, fcom, fcomp with
register operands, because this is a common idiom. Flag them with
a warning. Allow illegal faddp, fsubp, fsubrp, fmulp, fdivp,
fdivrp because gcc erroneously generates them. Also flag with a
warning.
* i386.h: Add suffix modifiers to most insns, and tighter operand
checks in some cases. Fix a number of UnixWare compatibility
issues with float insns. Merge some floating point opcodes, using
new FloatMF modifier.
(WORD_PREFIX_OPCODE): Rename to DATA_PREFIX_OPCODE for
consistency.
* i386.h: Change occurence of ShortformW to W|ShortForm. Add
IgnoreDataSize where appropriate.
