--- Comment #2 from Uroš Bizjak <ubizjak at gmail dot com> ---
The patch does only:
+expand_memory_blockage (void)
+{
+ if (targetm.have_memory_blockage)
+ emit_insn (targetm.gen_memory_blockage ());
+ else
+ expand_asm_memory_blockage ();
+}
So, if the target doesn't declare memory_blockage pattern, as is the
case with rs6000, I really fail to see what could go wrong here.
