* cselib.c (cselib_preserve_constants,
cfa_base_preserved_val): New static variables.
(preserve_only_constants): New function.
(cselib_reset_table): If cfa_base_preserved_val is non-NULL, don't
clear its REG_VALUES. If cselib_preserve_constants, don't
empty the whole hash table, but preserve there VALUEs with constants,
cfa_base_preserved_val and cfa_base_preserved_val plus constant.
(cselib_preserve_cfa_base_value): New function.
(cselib_invalidate_regno): Don't invalidate cfa_base_preserved_val.
(cselib_init): Change argument to int bitfield. Set
cselib_preserve_constants to whether CSELIB_PRESERVE_CONSTANTS
is in it.
(cselib_finish): Clear cselib_preserve_constants and
cfa_base_preserved_val.
* cselib.h (enum cselib_record_what): New enum.
(cselib_init): Change argument to int.
(cselib_preserve_cfa_base_value): New prototype.
* postreload.c (reload_cse_regs_1): Adjust cselib_init caller.
* dse.c (dse_step1): Likewise.
* cfgcleanup.c (thread_jump): Likewise.
* sched-deps.c (sched_analyze): Likewise.
* gcse.c (local_cprop_pass): Likewise.
* simplify-rtx.c (simplify_replace_fn_rtx): Add argument to callback.
If FN is non-NULL, call the callback always and whenever it returns
non-NULL just return that. Only do rtx_equal_p if FN is NULL.
* rtl.h (simplify_replace_fn_rtx): Add argument to callback.
* combine.c (propagate_for_debug_subst): Add old_rtx argument,
compare from with old_rtx and if it isn't rtx_equal_p, return NULL.
* Makefile.in (var-tracking.o): Depend on $(RECOG_H).
* var-tracking.c: Include recog.h.
(bb_stack_adjust_offset): Remove.
(vt_stack_adjustments): Don't call it, instead just gather the
adjustments using insn_stack_adjust_offset_pre_post on each bb insn.
(adjust_stack_reference): Remove.
(compute_cfa_pointer): New function.
(hard_frame_pointer_adjustment, cfa_base_rtx): New static variables.
(struct adjust_mem_data): New type.
(adjust_mems, adjust_mem_uses, adjust_mem_stores, adjust_insn): New
functions.
(get_address_mode): New function.
(replace_expr_with_values): Use it.
(use_type): Don't do cselib_lookup for VAR_LOC_UNKNOWN_P.
Use get_address_mode. For cfa_base_rtx return MO_CLOBBER.
(adjust_sets): Remove.
(add_uses): Don't add extra MO_VAL_USE for cfa_base_rtx plus constant.
Use get_address_mode.
(get_adjusted_src): Remove.
(add_stores): Don't call it. Never reuse expr SET. Don't add extra
MO_VAL_USE for cfa_base_rtx plus constant. Use get_address_mode.
(add_with_sets): Don't call adjust_sets.
(fp_setter, vt_init_cfa_base): New functions.
(vt_initialize): Change return type to bool. Move most of pool etc.
initialization to the beginning of the function from end. Pass
CSELIB_RECORD_MEMORY | CSELIB_PRESERVE_CONSTANTS to cselib_init.
If !frame_pointer_needed, call vt_stack_adjustment before mos
vector is filled, call vt_init_cfa_base if argp/framep has been
eliminated to sp. If frame_pointer_needed and argp/framep has
been eliminated to hard frame pointer, set
hard_frame_pointer_adjustment and call vt_init_cfa_base after
encountering fp setter in the prologue. For MO_ADJUST, call
log_op_type before pusing the op into mos vector, not afterwards.
Call adjust_insn before cselib_process_insn/add_with_sets,
call cancel_changes (0) afterwards.
(variable_tracking_main_1): Adjust for vt_initialize calling
vt_stack_adjustments and returning whether it succeeded or not.
* gcc.dg/guality/pr43051-1.c: New test.
