+// Preprocessor symbols must be defined, even if these are implemented

+//
+// R/W means read/write, B/L/N means big/little/native endianness.
+// The following macros require aligned access, compared to their
+// unaligned variants: AV_(COPY|SWAP|ZERO)(64|128), AV_[RW]N[8-64]A.
+// Incorrect usage may range from abysmal performance to crash
+// depending on the platform.
+//
+// The unaligned variants are AV_[RW][BLN][8-64] and AV_COPY*U.
+
+// Define AV_[RW]N helper macros to simplify definitions not provided
+// by per-arch headers.
