Bug ID: 96129
Summary: [11 regression] gcc.dg/vect/vect-alias-check.c etc.
FAIL
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
Target Milestone: ---
Target: sparc-sun-solaris2.11, armeb-none-linux-gnueabihf
Created attachment 48845
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=48845&action=edit
32-bit sparc-sun-solaris2.11 vect-alias-check.c.163t.vect
Between 20200707 (f75211822f8d84bb706421d3692e6c1cdbdfc3a8) and 20200708
(30fdaead5b7880c4e9f140618e26ad1c545642d5), two testcases regressed on
Solaris/SPARC (both 32 and 64-bit):
+FAIL: gcc.dg/vect/vect-alias-check.c -flto -ffat-lto-objects
scan-tree-dump-times vect "vectorized 1 loops" 1
+FAIL: gcc.dg/vect/vect-alias-check.c scan-tree-dump-times vect "vectorized 1
loops" 1
+FAIL: gcc.dg/vect/vect-live-5.c -flto -ffat-lto-objects scan-tree-dump-times
vect "vectorized 1 loops" 1
+FAIL: gcc.dg/vect/vect-live-5.c scan-tree-dump-times vect "vectorized 1 loops"
1
At the same time, an XPASS vanished:
-XPASS: gcc.dg/vect/vect-alias-check-1.c -flto -ffat-lto-objects
scan-tree-dump vect "using an address-based overlap test"
-XPASS: gcc.dg/vect/vect-alias-check-1.c scan-tree-dump vect "using an
address-based overlap test"
There's also a report for the regressions on ARM.
Dumps attached.

Quite some revs, two vectorizer changes. Do the FAILs still occur?

As the regressed failures, it's highly suspected to be duplicated of PR96376.
