2012-08-03 Andreas Schwab <schwab@linux-m68k.org>
* sysdeps/m68k/sysdep.h (ALIGNARG, ASM_TYPE_DIRECTIVE)
(ASM_SIZE_DIRECTIVE): Remove.
(ENTRY, END): Use .p2align. Use .type and .size instead of
ASM_TYPE_DIRECTIVE and ASM_SIZE_DIRECTIVE.
* sysdeps/m68k/asm-syntax.h (ALIGNARG, PROLOG, EPILOG, ALIGN)
(GLOBL): Remove unused macros.
