	* doc/c-i386.texi: Update .att_mnemonic and .intel_mnemonic.

	* config/tc-i386.c (set_intel_mnemonic): Set intel_mnemonic
	only.
	(md_assemble): Remove Intel mode workaround.
	(match_template): Check support for old gcc, AT&T mnemonic
	and Intel Syntax.
	(md_parse_option): Don't set intel_mnemonic to 0 for
	OPTION_MOLD_GCC.

gas/testsuite/

2008-01-05  H.J. Lu  <hongjiu.lu@intel.com>

	* gas/i386/intel.s: Add tests for fadd, faddp, fdiv, fdivp,
	fdivr, fdivrp, fmul, fmulp, fsub, fsubp, fsubr and fsubrp.

	* gas/i386/intel.d: Updated.
	* gas/i386/intel.e: Likewise.

2008-01-05  H.J. Lu  <hongjiu.lu@intel.com>

	* i386-gen.c (opcode_modifiers): Rename IntelMnemonic to
	ATTSyntax.

	* i386-opc.h (IntelMnemonic): Renamed to ..
	(ATTSyntax): This
	(Opcode_Modifier_Max): Updated.
	(i386_opcode_modifier): Remove intelmnemonic. Add attsyntax
	and intelsyntax.

	* i386-opc.tbl: Remove IntelMnemonic and update with ATTSyntax
	on fsub, fubp, fsubr, fsubrp, div, fdivp, fdivr and fdivrp.
	* i386-tbl.h: Regenerated.
