* gnu/gcj/runtime/FinalizerThread.java (init): New. Native.
(finalizerReady): Now native.

a primitive lock, and don't hold it while running the finalizers.

* name-lookup.c (cxx_saved_binding_make): Remove.
(store_binding): Add new bindings to a vector, using an
accumulator style, rather than adding them to a list.
(store_bindings): Adjust accordingly.
(store_class_bindings): Likewise.
(push_to_top_level): Likewise.
(pop_from_top_level): Likewise.
* optimize.c (maybe_clone_body): Must push_to_top_level and
pop_from_top_level calls outside of loop.
* parser.c (cp_parser_class_specifier): Move push_scope/pop_scope
calls here from cp_parser_late_parsing_default_args.
(cp_parser_save_default_args): Record the class type in which the
function is declared.
(cp_parser_late_parsing_default_args): Do not call
push_nested_class/pop_nested_class.

(unuse_fields): Remove.
* g++.dg/parse/defarg8.C: New test.
From-SVN: r84530
* builtins.c (fold_builtin_fputs): Don't bother converting the
return type to integer_type_node, as we've already checked that
the result will be ignored.
* tree-eh.c (tree_could_trap_p): Add support for -ftrapv such
that signed addition, subtraction, multiplication, division,
remainder, negation and absolute value may potentially trap.
* fold-const.c (fold_ignored_result): New function to strip
non-side-effecting tree nodes from an expression whose result
is ignored.
(fold_convert): Call fold_ignored_result when casting a value
to VOID_TYPE.
(omit_one_operand): Call fold_ignored_result on the "omitted"
operand when building a COMPOUND_EXPR.
(pedantic_omit_one_operand): Likewise.
* tree.h (fold_ignored_result): Prototype here.
* tree-ssa-ccp.c (ccp_fold_builtin): Call fold_ignored_result
when we're going to ignore the result.

* java/net/URLStreamHandler.java (parseURL): When url file part
doesn't contain a '/' just ignore context.

* rtlanal.c (insn_rtx_cost): New function, moved and renamed from
combine.c's combine_insn_cost.
* rtl.h (insn_rtx_cost): Prototype here.
* combine.c (combine_insn_cost): Delete function.
(combine_validate_cost): Update callers of combine_insn_cost to
call insn_rtx_cost instead.
(combine_instructions): Likewise. Use NONJUMP_INSN_P to avoid
requesting the rtx_cost of call and/or jump instructions.
* ifcvt.c (total_bb_rtx_cost): Use insn_rtx_cost instead of calling
rtx_cost directly. Don't request/use the cost of call or jump
instructions. Return -1 if the cost of any instruction can't be
determined (or the BB contains a function call).
(find_if_case_1): Abort transformation if total_bb_rtx_cost returns
-1 (i.e. can't determine the cost of any instruction or the basic
block contains a subroutine call).
(find_if_case_2): Likewise.
From-SVN: r84513
* rs6000.c (struct processor_costs): Change semantics of fields to
include the COST_N_INSNS scaling, and update all initializers.
(rs6000_rtx_costs): Don't use COSTS_N_INSNS on rs6000_cost fields.
Use COSTS_N_INSNS(1) for NOT, SIGN_EXTEND, ZERO_EXTEND and COMPARE.
Use rs6000_cost->fp for both FLOAT_TRUNCATE and UNSPEC_FRSP. When
optimizing for size, use COSTS_N_INSNS(1) for CALL and IF_THEN_ELSE.

name.

instruction, not after it.

signedness comes from outer type using precision rather than size.
