according to B&L paper.
* predict.h (DEF_PREDICTOR): New argument FLAGS.
* profile.c (compute_branch_probabilities): Cleanup way the edge
probabilities are computed and REG_BR_PROB notes are dropped; if
values does not match, emit error.
(init_branch_prob): Do error instead of warning when profile driven
feedback is missing or corrupt.

* ifcvt.c (noce_get_alt_condition): If the condition is a compare
against a constant, try to adjust the compare to have the desired
constant in it so that min/max optimizations happen more often.

* class.c (mark_primary_virtual_base): Don't adjust base
offsets here.

* jump.c (cleanup_barriers): New function.
* toplev.c (rest_of_compilation): Call cleanup_barriers
before loop optimizer and after bb_reorder.

recalculate the global regs which are alive when
removing dead code during a global update.

* params.def (PARAM_MAX_PENDING_LIST_LENGTH): Add parameter to
limit length of dependancy flush list.
* params.h (MAX_PENDING_LIST_LENGTH): Define.
* sched-int.h (struct deps): Add pending_flush_length field.
* sched-deps.c (flush_pending_lists): Last_pending_memory_flush now
has 1 element in it.
(sched_analyze_1): Use MAX_PENDING_LIST_LENGTH.
(sched_analyze): After a jump, if the pending memory flush list is too
large, flush the pending lists.
(init_deps): Initialize pending_flush_length to 0.

* java/util/Calendar.java (set): Never recompute fields here. They
will already be set if someone set time explicitly, and it can cause
problems to do so. Don't invalidate AM_PM setting if HOUR is set.
* java/util/GregorianCalendar.java (computeTime): Don't ignore an
HOUR setting if AM_PM is set. Don't try to ensure the HOUR value is
sane.
* java/text/SimpleDateFormat.java (defaultCentury): New field.
(readObject): Call set2DigitYearStart if appropriate so that
defaultCentury is calculated.
(SimpleDateFormat): Don't bother clearing calendar here. Call
computeCenturyStart().
(set2DigitYearStart): Calculate and set defaultCentury.
(format): Don't clone the calendar. Use "calendar" not "theCalendar"
everywhere.
(parse): Likewise. If the pattern is "y" or "yy" and it found exactly
2 numeric digits, use the 80-20 heuristic to parse the value into a
default century based on defaultCenturyStart.
(computeCenturyStart): Rewritten. Call set2DigitYearStart().
From-SVN: r44395
* function.c (locate_and_pad_parm): Also pad initial offset
so that the total argument size also includes the padding.
