Patch to add prototypes
- To: egcs at cygnus dot com
- Subject: Patch to add prototypes
- From: Bernd Schmidt <crux at pool dot informatik dot rwth-aachen dot de>
- Date: Mon, 6 Apr 1998 15:03:53 +0200 (MET DST)
Here's an updated version of a patch to add prototypes in a number of
random places. This one is against egcs-980328.
Bernd
* c-lex.c (is_class_name): Delete declaration.
(whitespace_cr): Make static and add prototype.
* c-lex.h (make_pointer_declarator, reinit_parse_for_function,
yylex, get_directive_line): Turn declarations into prototypes.
(position_after_whitespace, check_newline, yyerror,
forget_protocol_qualifiers, remember_protocol_qualifiers): Add
prototypes.
* genattr.c (extend_range, write_upcase, gen_attr, write_units): Add
prototypes.
* gencodes.c (gen_insn): Add prototype.
* genconfig.c (walk_insn, gen_insn, gen_expand, gen_split,
gen_peephole): Add prototypes.
* genflags.c (num_operands, gen_proto, gen_nonproto, gen_insn): Add
prototypes.
* gengenrtl.c (type_from_format, accessor_from_format, special_rtx,
special_format, find_formats, gendecl, genmacro, gendef, genlegend,
genheader, gencode): Add prototypes.
* genopinit.c (gen_insn): Add prototype.
* genoutput.c (output_prologue, output_epilogue, scan_operands,
process_template, validate_insn_alternatives, gen_insn, gen_peephole,
gen_expand, gen_split, n_occurrences): Add prototypes.
* genpeep.c (gen_peephole): Add prototype.
* loop.c (find_and_verify_loops, mark_loop_jump, prescan_loop,
reg_in_basic_block_p, consec_sets_invariant_p, libcall_other_reg,
labels_in_range_p, count_loop_regs_set, note_addr_stored,
loop_reg_used_before_p, scan_loop, replace_call_address,
skip_consec_insns, libcall_benefit, ignore_some_movables,
force_movables, combine_movables, rtx_equal_for_loop_p, move_movables,
strength_reduce, valid_initial_value_p, find_mem_givs, record_biv,
check_final_value, record_giv, update_giv_derive, basic_induction_var,
simplify_giv_expr, general_induction_var, consec_sets_giv,
check_dbra_loop, express_from, combine_givs_p, combine_givs,
product_cheap_p, maybe_eliminate_biv, maybe_eliminate_biv_1,
last_use_this_basic_block, record_initial, update_reg_last_use,
iteration_info, analyze_loop_iterations, insert_bct,
instrument_loop_bct, indirect_jump_in_function_p): Turn declarations
into prototypes.
