I've just bootstrapped the patch on sparc-sun-solaris2.12, which
uncovered a couple of testsuite failures:
+FAIL: gcc.dg/tree-ssa/split-path-5.c scan-tree-dump-times split-paths "Duplicat
ing join block" 2
+FAIL: gcc.dg/tree-ssa/split-path-5.c scan-tree-dump-times split-paths "Duplicat
ing join block" 2
Message doesn't occur at all.
+FAIL: gfortran.dg/ldist-1.f90 -O scan-tree-dump-not ldist "distributed: spl
it to"
Likewise.
