Bug ID: 103189
Summary: [12 regression] g++.dg/tree-ssa/pta-delete-1.C etc.
FAIL
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
CC: ebotcazou at gcc dot gnu.org
Target Milestone: ---
Target: sparc*-sun-solaris2.11
Between 20211109 (78dd0de956cbc5a021d3c5e3eb39308c3207936e) and 20211110
(86ffc845b2d0bff59832dcf3cf6518f1358e30ac),
several tests regressed on Solaris/SPARC (32 and 64-bit):
+FAIL: g++.dg/tree-ssa/pta-delete-1.C -std=gnu++14 execution test

+FAIL: gcc.dg/torture/pr45967.c -Os execution test
In both cases, the tests abort, but running under gdb this makes no sense:
* pta-delete-1.C:
Thread 2 received signal SIGABRT, Aborted.
[Switching to Thread 1 (LWP 1)]
0xfec5344c in __lwp_sigqueue () from /lib/libc.so.1
(gdb) where
#0 0xfec5344c in __lwp_sigqueue () from /lib/libc.so.1
#1 0xfeb9028c in raise () from /lib/libc.so.1
#2 0xfeb60578 in abort () from /lib/libc.so.1
#3 0x00010e1c in main () at
/vol/gcc/src/hg/master/local/gcc/testsuite/g++.dg/tree-ssa/pta-delete-1.C:23
yet gdb shows that y = 2 at this point.
* pr45967.c:
Thread 2 received signal SIGABRT, Aborted.
[Switching to Thread 1 (LWP 1)]
0xfec5344c in __lwp_sigqueue () from /lib/libc.so.1
(gdb) where
#0 0xfec5344c in __lwp_sigqueue () from /lib/libc.so.1
#1 0xfeb9028c in raise () from /lib/libc.so.1
#2 0xfeb60578 in abort () from /lib/libc.so.1
#3 0x00010c94 in main () at
/vol/gcc/src/hg/master/local/gcc/testsuite/gcc.dg/torture/pr45967.c:19
Again, the test aborts although gdb shows i = 1.
Unless someone has an idea what might have caused this, I'll have to run a
reghunt.

I wonder if you can attach .optimized dumps of valid revision and broken one.
It may be related to modref/PTA changes.

--- Comment #2 from Rainer Orth <ro at gcc dot gnu.org> ---
I'd started a reghunt already, thus the late reply. The culprit rev is
commit d70ef65692fced7ab72e0aceeff7407e5a34d96d
Author: Jan Hubicka <jh@suse.cz>
Date: Wed Nov 10 13:08:41 2021 +0100
Make EAF flags more regular (and expressive)
I'm attaching the dumps.

PR 103182 records pr45967-2.c failure. I suspect they are all the same issue.
