So, for #c3 testcase on x86_64-linux, I can confirm:
-bash-4.3$ rm -f pr81635.c.*; /opt/notnfs/gcc-bisect/obj/gcc/cc1.249895 -quiet
-ftree-slp-vectorize -O2 pr81635.c -fdump-tree-slp-details
-fdump-tree-vect-details; grep ectorized pr81635.c.*
pr81635.c:10:3: note: Basic block will be vectorized using SLP
pr81635.c:10:3: note: basic block part vectorized
pr81635.c:10:3: note: basic block vectorized
pr81635.c:18:1: note: not vectorized: not enough data-refs in basic block.
-bash-4.3$ rm -f pr81635.c.*; /opt/notnfs/gcc-bisect/obj/gcc/cc1.249896 -quiet
-ftree-slp-vectorize -O2 pr81635.c -fdump-tree-slp-details
-fdump-tree-vect-details; grep ectorized pr81635.c.*
pr81635.c:10:3: note: not vectorized: no grouped stores in basic block.
pr81635.c:18:1: note: not vectorized: not enough data-refs in basic block.
-bash-4.3$ rm -f pr81635.c.*; /opt/notnfs/gcc-bisect/obj/gcc/cc1.255629 -quiet
-ftree-slp-vectorize -O2 pr81635.c -fdump-tree-slp-details
-fdump-tree-vect-details; grep ectorized pr81635.c.*
pr81635.c:10:3: note: not vectorized: no grouped stores in basic block.
pr81635.c:18:1: note: not vectorized: not enough data-refs in basic block.
So r249896 regressed it. Richard, what happened to "Testing a fix"?
