check from branch delay code. Remove unnecessary check for branches.
2005-03-09 * config/tc-mips.c (dummy_opcode): Delete.Richard Sandiford1-312/+252
(nop_insn, mips16_nop_insn): New variables. (NOP_INSN): New macro. (insn_length, create_insn, install_insn, move_insn, add_fixed_insn) (add_relaxed_insn, insert_into_history, emit_nop): New functions. (md_begin): Initialize nop_insn and mips16_nop_insn. (append_insn): Use the new emit_nop function to add nops, recording them in the history buffer. Use add_fixed_insn or add_relaxed_insn to reserve room for the instruction and install_insn to install the final form. Use insert_into_history to record the instruction in the history buffer. Use move_insn to do delay slot filling. (mips_emit_delays): Use add_fixed_insn instead of the emit_nop macro. (macro_build, mips16_macro_build, macro_build_lui, mips_ip) (mips16_ip): Use create_insn to initialize mips_cl_insns.
2005-03-09 * config/tc-mips.c (INSERT_BITS, EXTRACT_BITS, INSERT_OPERAND)Richard Sandiford1-203/+168
(EXTRACT_OPERAND, MIPS16_INSERT_OPERAND, MIPS16_EXTRACT_OPERAND): New. (insn_uses_reg, reg_needs_delay, append_insn, macro_build) (mips16_macro_build, macro_build_lui, mips16_macro, mips_ip) (mips16_ip): Use the new macros instead of explicit masks and shifts.
