32-bit sparc-sun-solaris2.11 slp-43.c.163t.vect
Between 20200708 (30fdaead5b7880c4e9f140618e26ad1c545642d5) and 20200709
(fab263ab0fc10ea08409b80afa7e8569438b8d28), a couple of testcases regressed on
Solaris/SPARC, both 32 and 64-bit:
+XPASS: gcc.dg/vect/bb-slp-32.c -flto -ffat-lto-objects scan-tree-dump slp2
"vectorization is not profitable"
+XPASS: gcc.dg/vect/bb-slp-32.c scan-tree-dump slp2 "vectorization is not
profitable"
+XPASS: gcc.dg/vect/bb-slp-9.c -flto -ffat-lto-objects scan-tree-dump-times
slp2 "basic block vectorized" 1
+XPASS: gcc.dg/vect/bb-slp-9.c scan-tree-dump-times slp2 "basic block
vectorized" 1
+FAIL: gcc.dg/vect/slp-43.c -flto -ffat-lto-objects scan-tree-dump-times vect
"vectorized 1 loops" 2
+FAIL: gcc.dg/vect/slp-43.c scan-tree-dump-times vect "vectorized 1 loops" 2
+FAIL: gcc.dg/vect/slp-45.c -flto -ffat-lto-objects scan-tree-dump-times vect
"vectorized 1 loops" 13
+FAIL: gcc.dg/vect/slp-45.c scan-tree-dump-times vect "vectorized 1 loops" 13
There's a similar regression reported on ia64-suse-linux-gnu.
