+// We want to make sure that the registers that Spire generates
+// are used, even if there are "dead" parameter earlier in the program.
+//
+// In this case, we declare two each of textures, samplers, and constant
+// buffers, and then only use the second one.
+// Left to its own devices, the HLSL compiler would usually shift the
+// object that was used up to binding slot zero, and eliminate the one
+// that wasn't used.
+// We expect Spire to generate explicit annotations that stop this from
+// happening.
