--- Comment #8 from Rainer Orth <ro at gcc dot gnu.org> ---
The new testcase is FAILing on sparc-sun-solaris2.12 (and according to
gcc-testresults
on mips64el-unknown-linux-gnu and ia64-suse-linux-gnu):
+FAIL: gfortran.dg/vect/pr60510.f -O0 scan-tree-dump vect "reduction chain"
+FAIL: gfortran.dg/vect/pr60510.f -O0 scan-tree-dump-times vect "vectorized

Also (I suppose they are related, otherwise it would be a strange coincidence
since they also FAIL on ia64-suse-linux-gnu) the following tests regressed on
32 and 64-bit sparc.
+FAIL: gcc.dg/vect/bb-slp-1.c -flto -ffat-lto-objects scan-tree-dump-times
slp1 "basic block vectorized" 1
+FAIL: gcc.dg/vect/bb-slp-1.c scan-tree-dump-times slp1 "basic block
vectorized" 1
+FAIL: gcc.dg/vect/bb-slp-16.c -flto -ffat-lto-objects scan-tree-dump-times
slp1 "basic block vectorized" 1
+FAIL: gcc.dg/vect/bb-slp-16.c scan-tree-dump-times slp1 "basic block
vectorized" 1
+FAIL: gcc.dg/vect/bb-slp-2.c -flto -ffat-lto-objects scan-tree-dump-times
slp1 "basic block vectorized" 1
+FAIL: gcc.dg/vect/bb-slp-2.c scan-tree-dump-times slp1 "basic block

I'm attaching two of the dumps.
