* combine.c (get_last_value): If the last set of a register
is after subst_low_cuid, then we can not use it to determine
the register's last value.
From-SVN: r30062
* haifa-sched.c (add_dependence): Only check/update the cache
if it exists.
(remove_dependence): Likewise.
(schedule_insns): Only create the true_dependency_cache if the
average number of instructions in a basic block is very large.
From-SVN: r30058

Prototype for exported functions.

(one_classic_gcse_pass): Call compute_ae_kill with parameters.
(pre_insert, s_preds, s_succs, num_preds, num_succs): Delete.
(gcse_main): No longer call compute_preds_succs. Rebuild the
set table after reach pre pass.

block.
(compute_code_hoist_vbeinout): New new edge based routines.

that work with the new cfg datastructures and work with edges
instead of blocks.
From-SVN: r30055
* reload.h (struct reload): Add new fields "mode" and "nregs".
* reload1.c: Change all occurrences of reload_mode and reload_nregs
to reference the "mode" and "nregs" field within struct reload.
From-SVN: r30051
* haifa-sched.c (true_dependency_cache): New.
(add_dependence): Use the true dependency cache to avoid expensive
walks down the LOG_LINKS dependency list. Add entries to the
cache as necessary.
(remove_dependence): Remove entries from the true dependency cache
as needed.
(schedule_insns): Allocate and initialize and free the true
dependency cache.
From-SVN: r30050
* java/lang/ClassLoader.java (getSystemResource): Use
getSystemClassLoader instead of ClassLoader.system.
(getSystemResourceAsStream): Ditto.
* java/lang/natClassLoader.cc (redirect): Make static and
remove #ifdef INTERPRETER so it is always defined.
(getVMClassLoader0): Remove #ifdef INTERPRETER so it always
returns a VMClassLoader.
* java/util/ResourceBundle.java (trySomeGetBundle): Create a
PropertyResourceBundle if a properties file is found before a
ResourceBundle class.
From-SVN: r30048
* haifa-sched.c (compute_block_forward_dependencies): Only check
for notes, deleted insns and duplicates if ENABLE_CHECKING is defined.
From-SVN: r30042
* lex.c (lang_init_options): Set flag_bounds_check as "unspecified".

From-SVN: r30038
* flags.h (flag_bounds_check, flag_bounded_pointers): New extern decls.
* toplev.c (flag_bounds_check, flag_bounded_pointers): New flags.
(f_options): Add "bounded-pointers" and "bounds-check" entries.
* c-lang.c (lang_init_options): Set flag_bounds_check as "unspecified".
(lang_init): Set default for flag_bounds_check if still "unspecified".
From-SVN: r30035
* pa.c (move_operand): Rely on memory_address_p to determine the
validity of non-indexed memory addresses.
* pa.h (GO_IF_LEGITIMATE_ADDRESS): Allow LO_SUM with a symbolic
operand in DFmode and SFmode when generating PA2.0 code.
From-SVN: r30025
* cse.c: Include hashtab.h instead of splay-tree.h
(struct cse_reg_info): No longer use variant union. Add new
field "regno". All references changed to avoid union.
(cse_reg_info_used_list, cse_reg_info_used_list_end): New variables.
(free_cse_reg_info): Remove.
(hash_cse_reg_info, cse_reg_info_equal_p): New functions.

(new_basic_block): Similarly.
