* jump.c (jump_optimize): Initialize mappings from INSN_UID to
EH region if exceptions are enabled and we're performing cross
jump optimizations.
(find_cross_jump): Exit loop if the insns are in different EH regions.
From-SVN: r23475
* warn_summary (longLineFilter): New shell function to encapsulate
this functionality. It is off by default, only active if -llf
flag is specified.
(subdirectoryFilter): Fix bug in filtering which made some
subdirectory warnings erroneously appear in the toplevel set.
(stageNfilter): Renamed from `stageNwarns'. Updated to collect
warnings from stage1 as well as stage0, which means warnings from
outside the bootstrap directory. Eg, the libraries, etc.
(warningFilter): New shell function to encapsulate this
functionality.
(keywordFilter): New shell function to encapsulate this
functionality.
Store data in a temp file rather than calculating it 3x. Arrange
to remove it on exit and signals.
Add -pass/-wpass flags to do "pass through" (i.e. manual
inspection) of bootstrap output from a particular stageN as well
as language subdirs.
Add better comments/documentation.

Delete code to compute basic_block_drops_in.
After calling make_edges, mark blocks reached by current block live.
Update test for unreachable live blocks.

changed.
Simplify to call add_edge_to_label when a LABEL_REF is found.

(free_basic_block_vars): Don't free basic_block_drops_in.

dump_bb_data instead.

and uid_block_number.
Simply copy the previously computed cfg.
(dump_bb_data): New arg LIVE_INFO. All callers changed.
Print register lifetime information if LIVE_INFO is nonzero.

* reload1.c (struct elim_table): Delete MAX_OFFSET member.
(update_eliminable_offsets): Don't compute it.
(set_initial_elim_offsets): Don't initialize it.
Break out some code into set_initial_label_offsets so the rest of
this function can be called from reload_as_needed.
Assume that INITIAL_FRAME_POINTER_OFFSET is defeined when
ELIMINABLE_REGS isn't.
(set_initial_label_offsets): New function, broken out of
set_initial_elim_offsets.
(set_offsets_for_label): New function, broken out of set_label_offsets
and reload_as_needed.
(reload): Call the two new functions.
(reload_as_needed): Call set_initial_elim_offsets instead of
duplicating the code. Likewise for set_offsets_for_label.

* c-lex.c (init_parse) [USE_CPPLIB=1]: After calling
cpp_start_read, set yy_cur and yy_lim to read from
parse_in.token_buffer, so that we'll see the first #line
directive.
* cpplib.c (cpp_start_read): finclude the main input file
before processing -include/-imacros. Process -imacros and
-include separately, and handle -include by stacking a
buffer for the file in question as if it'd been #included.

USE_CPPLIB is on.

file_name_list there also.
