PR debug/42977
* cselib.c (n_useless_values): Document handling of debug locs.
(n_useless_debug_values, n_debug_values): New variables.
(new_elt_loc_list): Don't add to debug values, keep count.
(promote_debug_loc): New.
(cselib_reset_table): Zero new variables.
(entry_and_rtx_equal_p): Promote debug locs.
(discard_useless_locs): Increment n_useless_debug_values for
debug values.
(remove_useless_values): Adjust n_useless_values and n_debug_values
with n_useless_debug_values.
(add_mem_for_addr): Promote debug locs.
(cselib_lookup_mem): Likewise.
(cselib_lookup_addr): Renamed to...
(cselib_lookup_addr_1): ... this. Promote debug locs.
Don't call...
(cselib_log_lookup): ... this. Turn into...
(cselib_lookup_addr): ... new wrapper.
(cselib_lookup_from_insn): New.
(cselib_invalidate_regno): Increment n_useless_debug_values for
debug values.
(cselib_invalidate_mem): Likewise.
(cselib_process_insn): Take n_deleted and n_debug_values into
account to guard remove_useless_value call.
(cselib_finish): Zero n_useless_debug_values.
* cselib.h (cselib_lookup_from_insn): Declare.
* sched-deps.c (sched_analyze_1): Use cselib_lookup_from_insn.
