================
Comment at: llvm/test/CodeGen/AArch64/GlobalISel/postlegalizer-combiner-identity.mir:18
+    ; CHECK: RET_ReallyLR implicit $x0
+    %a:_(s64) = G_CONSTANT i64 40
+    %b:_(s64) = G_CONSTANT i64 0
----------------
Maybe the LHS ought to be a copy from a phys reg, so this test doesn't get accidentally repurposed if someone adds a constant-folding combines to it.
