+Constant Buffer Loads
+---------------------
+
+*relevant types: CBuffers*
+
+The `CBufferLoadLegacy`_ operation, which despite the name is the only
+supported way to load from a cbuffer in any DXIL version, loads a single "row"
+of a cbuffer, which is exactly 16 bytes. The return value of the operation is
+represented by a `CBufRet`_ type, which has variants for 2 64-bit values, 4
+32-bit values, and 8 16-bit values.
+
+We represent these in LLVM IR with 3 separate operations, which return a
+2-element, 4-element, or 8-element struct respectively.
