* tree-ssa-operands.c (add_call_clobber_ops): Use SFT_PARENT_VAR
to try to avoid clobbering pieces of structures when we know
something about the whole structure.
* tree-ssa-alias.c (create_sft): Set SFT_PARENT_VAR
From-SVN: r109651
* config/m32c/addsub.md (addhi3): Add two more alternatives, for
mova with fb, and for fb+0 -> An.
* config/m32c/mov.md (peephole2): Fix enabling logic.
* config/m32c/m32c.h (CTOR_LIST_BEGIN, CTOR_LIST_END,
DTOR_LIST_BEGIN, DTOR_LIST_END, CTORS_SECTION_ASM_OP,
DTORS_SECTION_ASM_OP, INIT_ARRAY_SECTION_ASM_OP,
FINI_ARRAY_SECTION_ASM_OP): Define.
* config/m32c/m32c.c (m32c_legitimize_address): Remove temporary variable.
(m32c_legitimize_reload_address): New logic to reload FB to An.
(m32c_output_reg_push): Add newline.
(m32c_output_reg_pop): Likewise.

* intrinsics/c99_functions.c: Add function prototypes to avoid
warnings from -Wstrict-prototypes -Wmissing-prototypes. On Tru64
work around a brain-dead libm by redirecting calls to cabs{,f,l}
to a local __gfc_cabs{,f,l}.

* tree-ssa-threadupdate.c (threaded_edges): New VEC to
hold edge pairs.
(mark_threaded_blocks, register_jump_thread): New functions.
(thread_through_all_blocks): Remove unwanted argument. No
longer rely on e->aux to communicate thread target info.
Call mark_threaded_blocks. Release the threaded_blocks
bitmap and threaded_edges vector when complete.
* tree-ssa-dom.c (struct edge_info): Remove redirection_target field.
(threaded_blocks): Remove.
(tree_ssa_dominator_optimize): Remove initialization and
finalization of threaded_blocks. Simplify call to
thread_through_all_blocks.
(thread_across_edge): Call register_jump_thread rather than
storing thread information into e->aux.
(free_all_edge_infos): Simplify now that e->aux is no longer
used to communicate with thread_through_all_blocks.
* tree-flow.h (thread_through_all_blocks): Update prototype.
(register_jump_thread): Prototype.

* combine.c (struct undo): Remove is_int. Enumify types of undos.
Allow undoing set of machine mode.
(do_SUBST): Use enums instead of is_int.
(do_SUBST_MODE): New function.
(SUBST_MODE): New macro.
(try_combine): Use SUBST_MODE/PUT_MODE instead of generating a new
reg and trying to replace reg_regno_rtx with a new register.

(distribute_notes): Remove code that tried to update reg notes
for regno_reg_rtx changes.
