+ * mips.c (abort_with_insn): Make function static, add a prototype,
+ constify 2nd parameter and mark with ATTRIBUTE_NORETURN.
+ (current_function_file, mips_cpu_string, mips_isa_string,
+ mips_abi_string, mips_no_mips16_string, mips_entry_string,
+ mips_move_1word, mips_move_2words, output_block_move, load_store,
+ override_options, make_temp_file, mips16_fp_args): Qualify a char*
+ with the `const' keyword.
+
+ * mips.h (current_function_file, mips_cpu_string, mips_isa_string,
+ mips_abi_string, mips_entry_string, mips_no_mips16_string,
+ mips_move_1word, mips_move_2words, output_block_move): Likewise.
+ (abort_with_insn): Remove extern prototype.
+
+ * mips.md: Qualify a char* with the `const' keyword.
+ Remove many unused variables named `label'.
