cc1plus stats are now:
Alias oracle query stats:
refs_may_alias_p: 62971744 disambiguations, 73160711 queries
ref_maybe_used_by_call_p: 141176 disambiguations, 63867883 queries
call_may_clobber_ref_p: 23573 disambiguations, 29322 queries
nonoverlapping_component_refs_p: 0 disambiguations, 37720 queries
nonoverlapping_refs_since_match_p: 19432 disambiguations, 55659 must overlaps, 75860 queries
aliasing_component_refs_p: 54724 disambiguations, 753570 queries
TBAA oracle: 24124230 disambiguations 56228428 queries
16058141 are in alias set 0
10338303 queries asked about the same object
125 queries asked about the same alias set
0 access volatile
3919230 are dependent in the DAG
1788399 are aritificially in conflict with void *
Modref stats:
modref use: 10408 disambiguations, 46993 queries
modref clobber: 1418549 disambiguations, 1951251 queries
4898707 tbaa queries (2.510547 per modref query)
396878 base compares (0.203397 per modref query)
PTA query stats:
pt_solution_includes: 975364 disambiguations, 13604284 queries
pt_solutions_intersect: 1026606 disambiguations, 13181198 queries
So compared to
https://gcc.gnu.org/pipermail/gcc-patches/2020-September/554692.html we get 25%
use disambiguations and 91% more clobber disambiguations.

Alias oracle query stats:
refs_may_alias_p: 2056905 disambiguations, 2317461 queries
ref_maybe_used_by_call_p: 7137 disambiguations, 2093762 queries
call_may_clobber_ref_p: 234 disambiguations, 234 queries
nonoverlapping_component_refs_p: 0 disambiguations, 4313 queries
nonoverlapping_refs_since_match_p: 329 disambiguations, 10200 must overlaps, 10616 queries
aliasing_component_refs_p: 858 disambiguations, 34600 queries
TBAA oracle: 894996 disambiguations 1695991 queries
138346 are in alias set 0
470668 queries asked about the same object
0 queries asked about the same alias set
0 access volatile
191666 are dependent in the DAG
315 are aritificially in conflict with void *
Modref stats:
modref use: 842 disambiguations, 2265 queries
modref clobber: 14833 disambiguations, 28900 queries
34884 tbaa queries (1.207059 per modref query)
5041 base compares (0.174429 per modref query)
PTA query stats:
pt_solution_includes: 313372 disambiguations, 525724 queries
pt_solutions_intersect: 130374 disambiguations, 415138 queries
So about twice many use and 40% clobber disambiguations.
Bootstrapped/regtested x86_64-linux, I plan to commit it later today after
more testing.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
