* tree-inline.c (expand_call_inline): Make the statement
expression we generate have a COMPOUND_STMT.
From-SVN: r54153
* gcse.c (cprop_cc0_jump): Function deleted.
(cprop_jump): Take an additional argument which is the possibly
NULL cc setting insn immediately before the conditional jump.
When a MODE_CC set is present, substitute it into the JUMP_INSN
before attempting the constant propagation.
(cprop_insn): Recognize cc setters followed by conditional jumps
as a special case. Use cprop_jump instead of cprop_cc0_jump.
(cprop_one_pass): Call bypass_conditional_jumps if altering jumps.
(find_bypass_set): New function based upon find_avail_set used by
cprop, but finds constant expressions available at the end of
basic blocks.
(bypass_block): New function. Given a basic block that begins
with a conditional jump and multiple incoming edges, perform
the jump bypass optimization.
(bypass_conditional_jumps): New function. Call bypass_block with
each suitable basic block in the CFG using a simple single pass.
From-SVN: r54152
* tree.c (real_minus_onep): New function to test for -1.0.
* fold-const.c (fold) [MULT_EXPR]: Optimize -1.0*x into -x.
* gcc.dg/fnegate-1.c: New test case.
From-SVN: r54149
* config/avr/avr.c (avr_mcu_types): Remove devices that were once
expected, but don't really exist: atmega83, atmega85, attiny10.
* config/avr/avr.h (LINK_SPEC): Update to use the new avr[1-5] ld
emulations for all devices.
(CRT_BINUTILS_SPECS): Remove atmega83, atmega85, attiny10.
* config/avr/t-avr (MULTILIB_MATCHES): Remove atmega83, atmega85.
From-SVN: r54146

(BB_VISITED): New flag.
(struct loop): New field pred, removed field shared.
(struct loops): New field parray.
(LOOP_EXITS_DOMS): Removed.
(flow_loop_tree_node_add, flow_loop_tree_node_remove,
flow_loop_nested_p, flow_bb_inside_loop_p, get_loop_body,
dfs_enumerate_from, loop_preheader_edge, loop_latch_edge,
add_bb_to_loop, remove_bb_from_loops, find_common_loop,
verify_loop_structure): Declare.
* cfg.c (entry_exit_blocks): Initialize loop_father field.
* cfganal.c (dfs_enumerate_from): New function.
* cfgloop.c (HEAVY_EDGE_RATIO): New constant.
(flow_loop_entry_edges_find, flow_loop_exit_edges_find,
flow_loop_nodes_find, flow_loop_level_compute, flow_loop_nested_p,

flow_loop_tree_node_add, flow_loop_level_compute,
flow_loops_level_compute, flow_loop_scan, flow_loops_update,
flow_loop_outside_edge_p): Modified for new infrastructure.
(make_forwarder_block, canonicalize_loop_headers, glb_enum_p,
redirect_edge_with_latch_update, flow_loop_free): New static functions.
(flow_loop_tree_node_remove, flow_bb_inside_loop_p,
get_loop_body, add_bb_to_loop, remove_bb_from_loops,
find_common_loop, verify_loop_structure, loop_latch_edge,
loop_preheader_edge): New functions.
(flow_loops_cfg_dump): Do not show dominators, as this information
does not remain up to date long.
(flow_loops_find): Store results in new format.
* predict.c (propagate_freq, estimate_probability,
estimate_loops_at_level, estimate_bb_frequencies): Use new loop
infrastructure.

* include/bits/stl_bvector.h: Use UL suffix for unsigned longs.
* testsuite/23_containers/vector_bool.cc (test02): New test.

* c-decl.c (struct binding_level): Change int field n_incomplete
to tree list incomplete_list.
(clear_binding_level): Init field with NULL.
(pushdecl): Add incomplete type to list.
(mark_binding_level): Mark the incomplete list.
(finish_struct): Scan the incomplete list for types instead
of all decls in the current binding level.

* i386.c (classify_argument): Properly handle base types.
* dwarf2out.c (expand_builin_init_dwarf_reg_sizes):
Store first DWARF_FRAME_REGISTERS dwarf registers, not pseudo
registers.
From-SVN: r54106
* gcse.c (gcse_emit_move_after): New.
(pre_delete, hoist_store): Use it.
* reload1.c (emit_input_reload_insns): Use constrain_operands
instead of constraint_accepts_reg_p to verify optimization.
(constraint_accepts_reg_p): Kill
* reload1.c (reload_cse_delete_noop_set): Kill.
(reload_cse_simplify): use delte_insn_and_edges.

source directory.
* gnat_ug.texi: Remove CVS keywords, correct version number.
Set file name correctly.
