+    $vgpr3 = FLAT_LOAD_DWORD $vgpr1_vgpr2, 0, 0, 0, 0, implicit $exec, implicit $flat_scr :: (load 4 from %ir.flat4)
+    $vgpr4 = FLAT_LOAD_DWORD $vgpr1_vgpr2, 0, 0, 0, 0, implicit $exec, implicit $flat_scr :: (load 4 from %ir.global4)
+    $vgpr0 = V_MOV_B32_e32 $vgpr3, implicit $exec
----------------
Can you keep just load from flat here? The other load obscures the result.
