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

* 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".
