* tm.texi (Caller Saves): Say that DEFAULT_CALLER_SAVES has no
effect when -O2 and higher.
* invoke.texi (Optimize Options): Likewise for -fcaller-saves.
From-SVN: r21848
* regclass.c: Changed register set documentation to be consistent
with GCC behaviour.
* final.c (final_start_function) Removed redundant test for
call_fixed_regs.
From-SVN: r21847
* rtl.h (rtx_function): New type.
(for_each_rtx): New function.
* rtlanal.c (for_each_rtx): Define it.
* recog.c (change_t): New type.
(change_objects, change_old_codes, change_locs, change_olds):
Replace with ...
(changes): New variable.
(validate_change): Dynamically allocate room for more changes, if
necessary. Uses changes array instead of change_objects, etc.
(apply_change_group): Use changes array instead of
change_objects, etc.
* loop.c (loop_mem_info): New type.
(loop_mems): New variable.
(loop_mems_idx): Likewise.
(looop_mems_allocated): Likewise.
(scan_loop): Remove nregs parameter.
(next_insn_in_loop): New function.
(load_mems_and_recount_loop_regs_set): Likewise.
(load_mems): Likewise.
(insert_loop_mem): Likewise.
(replace_loop_mem): Likewise.
(replace_label): Likewise.
(INSN_IN_RANGE_P): New macro.
(loop_optimize): Don't pass max_reg_num() to scan_loop.
(scan_loop): Remove nregs parameter, compute it after any new
registers are created by load_mems. Use INSN_IN_RANGE_P and
next_insn_in_loop rather than expanding them inline. Call
load_mems to load memory into pseudos, if appropriate.
(prescan_loop): Figure out whether or not there are jumps from the
loop to targets other than the label immediately following the
loop. Call insert_loop_mem to notice all the MEMs used in the
loop, if it could be safe to pull MEMs into REGs for the duration
of the loop.
(strength_reduce): Use next_insn_in_loop. Tweak comments.

* config/sparc/sparc.c (finalize_pic): Check for the correct
nonlocal_goto_receiver UNSPEC number.
* config/sparc/sparc.md (nonlocal_goto_receiver): Add comment
making note of this dependency existing in sparc.c
From-SVN: r21842
* expr.c (emit_block_move): Do not call memcpy as a libcall
instead build up a CALL_EXPR and call it like any other
function.
(clear_storage): Similarly for memset.

statement after end of loop label.
From me...
* config/sparc/sparc.c (ultra_types_avail): New variable.
(ultra_build_types_avail): New function to record mask of insn
types in ready list at this cycle.
(ultrasparc_sched_reorder): Call it.
(ultra_find_type): Use it to quicken the search. Also simplif
dependency check, don't use rtx_equal_p because we know exactly
what we are looking for.
From-SVN: r21817
* cp-tree.h (enter_scope_of): New function.
* parse.y (complex_direct_notype_declarator): Use it.
* semantics.c (enter_scope_of): New function.
From-SVN: r21812
* tree.c (build_index_type): Copy TYPE_SIZE_UNIT from sizetype
to itype.
* c-decl.c (finish_enum): Copy TYPE_SIZ_UNIT from enumtype to tem.

* rs6000.c (secondary_reload_class): For TARGET_ELF, indicate that
a BASE_REGS register is needed as an intermediate when copying
a symbolic value into any register class other than BASE_REGS.
From-SVN: r21808
* rs6000.c (secondary_reload_class): For TARGET_ELF, indicate that
a BASE_REGS register is needed as an intermediate when copying
