[patch] m68k: Revert my ASSEMBLER_DIALECT patches.


Hi,

Attached is a patch to revert three patches of mine related to
ASSEMBLER_DIALECT.

On m68k, people use '{' and '}' in bitfield instructions.  One person
told me on IRC that Linux kernel uses one of those instructions.
Since ASSEMBLER_DIALECT uses '{' and '}' as special characters to
describe dialects, my patches broke backward compatibility.

This patch reverts my ASSEMBLER_DIALECT.  Too bad.

Committed as obvious.

Kazu Hirata

2007-10-10  Kazu Hirata  <kazu@codesourcery.com>

	Revert:
	2007-10-09  Kazu Hirata  <kazu@codesourcery.com>
	* longlong.h (count_leading_zeros): Replace '{' and '}' with '%{'
	and '%}', respectively.

	Revert:
	2007-10-09  Kazu Hirata  <kazu@codesourcery.com>
	* config/m68k/m68k.c (print_operand): Handle '{' and '}'.
	* config/m68k/m68k.h (PRINT_OPERAND_PUNCT_VALID_P): Accept '{'
	and '}'.
	* config/m68k/m68k.md: Replace '{' with '%{' where '{' is
	meant to be output.

	Revert:
	2007-10-07  Kazu Hirata  <kazu@codesourcery.com>
	* config/m68k/m68k.c, config/m68k/m68k.md: Use the assembly
	syntax for ASSEMBLER_DIALECT.
	* config/m68k/m68k.h (ASSEMBLER_DIALECT): New.
