Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization

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.
