* cse.c (cse_find_path): Don't wrap a gcc_assert in ENABLE_CHECKING.
(cse_extended_basic_block): When truncating a path while processing
it, make sure to clear the visited bit on the basic blocks in the
truncated part of the path.
(cse_main): Use reverse completion order, not DFS order, to walk
the CFG.
(gate_handle_cse): Revert erroneous commit of a counter.
From-SVN: r119985

* cse.c (this_insn_cc0, this_insn_cc0_mode): New global
variables, moved out from cse_insn.
(prev_insn): Remove this global variable).
(new_basic_block): Don't set it.
(cse_insn): Idem. Also, move code to delete unused CC0-setter
insns and code to set prev_insn_cc0 and prev_insn_cc0_mode
from here...
(cse_extended_basic_block): ...to here. Do not clear
prev_insn_cc0 until after recording equivalences from jumps.

* cse.c: (struct cse_basic_block_data): Remove LAST field.
(struct branch_path): Remove BRANCH and TAKEN fields. Add new
BB field.
(cse_visited_basic_blocks): New static bitmap.
(cse_end_of_basic_block, cse_basic_block): Remove.
(cse_find_path, cse_dump_path, cse_prescan_path,
cse_extended_basic_block): New static functions.
(cse_insn): Don't CSE over setjmp calls. Use the CFG to find
basic block boundaries. Don't record jump equivalences here.
Update the CFG after doing in-place replacement of the SET_SRC.
(cse_main): Rewrite. Look for extended basic block headers
and call cse_extended_basic_block on them until all paths that
start at this header are exhausted.
(rest_of_handle_cse): Verify that the CFG is incrementally updated
and correct after cse_main.
Don't call delete_trivially_dead_insns, let cfgcleanup do that.
(rest_of_handle_cse2): Verify the CFG here, too, after cse_main.
(pass_cse): Add TODO_verify_flow.
(pass_cse2): Likewise.

* cse.c (cse_altered): Remove.
(record_jump_equiv): Make true/false argument a bool instead
of an int.
(cse_insn): Don't set cse_altered. Use delete_insn_and_edges
where appropriate. Emit a new jump before the existing one
instead of after so that delete_insn_and_edges removes the
dead edges properly. Check any_condjump_p before calling
record_jump_equiv.
(cse_basic_block): Check any_condjump_p before calling
record_jump_equiv.
(cse_main): Don't set/check cse_altered. Remove USE_C_ALLOCA.

* cse.c (enum taken): Remove PATH_AROUND.
(addr_affects_sp_p, invalidate_skipped_set,
invalidate_skipped_block): Remove.
(cse_end_of_basic_block): Remove skip_blocks and related code.
(cse_main): Don't test for flag_cse_skip_blocks.
Update cse_end_of_basic_block call.
(cse_basic_block): Likewise. Remove PATH_AROUND case. Remove
code to lengthen the path if a jump was simplified.

* cse.c (fold_rtx): Correctly associate shifts when const_arg1 and/or
inner_const are negative or greater than or equal to the bitsize of
MODE. If SHIFT_COUNT_TRUNCATED is false, the values aren't associated.
Otherwise, the values are masked using GET_MODE_BITSIZE (mode) - 1.
Simplify complicated if statement. For ASHIFT and LSHIFTRT, return
CONST0_RTX (mode) when the new shift count is greater than or equal to
to the bitsize of the object being shifted and XEXP (y, 0) has no side
effects.
