+       * cse.c (table_size): New static variable.
+       (new_basic_block): Initialize it to 0.
+       (remove_from_table): Decrement it.
+       (insert): Increment it.
+       (fold_rtx_mem_1): New function, renamed from fold_rtx_mem.
+       (fold_rtx_mem): Enforce a cap on the recursion depth.  Call
+       fold_rtx_mem_1 if under the cap.
+       (fold_rtx) <RTX_COMM_ARITH>: In the associative case, delay a little
+       the lookup of the equivalent expression and test for equality of the
+       first operand of the equivalent expression before in turn looking up
+       an equivalent constant for the second operand.
