	* mips.h (INSN_TRAP): Rename to...
	(INSN_NO_DELAY_SLOT): ... this.
	(INSN_SYNC): Remove macro.

gas/
2011-07-24  Maciej W. Rozycki  <macro@codesourcery.com>

	* config/tc-mips.c (can_swap_branch_p): Adjust for the rename of
	INSN_TRAP to INSN_NO_DELAY_SLOT.  Remove the check for INSN_SYNC
	as well as explicit checks for ERET and DERET when scheduling
	branch delay slots.

opcodes/
2011-07-24  Maciej W. Rozycki  <macro@codesourcery.com>

	* mips-opc.c (NODS): New macro.
	(TRAP): Adjust for the rename of INSN_TRAP to INSN_NO_DELAY_SLOT.
	(DSP_VOLA): Likewise.
	(mips_builtin_opcodes): Add NODS annotation to "deret" and
	"eret". Replace INSN_SYNC with NODS throughout.  Use NODS in
	place of TRAP for "wait", "waiti" and "yield".
	* mips16-opc.c (NODS): New macro.
	(TRAP): Adjust for the rename of INSN_TRAP to INSN_NO_DELAY_SLOT.
	(mips16_opcodes):  Use NODS in place of TRAP for "jalrc", "jrc",
	"restore" and "save".
