+C * The zero-offset of popcount is misassembled to the offset-less form, which
+C is one byte shorter and therefore will mess up the switching code.
+C * The outdated gas used in FreeBSD and NetBSD cannot handle the POPCNT insn,
+C which is the main reason for our usage of '.byte'.
+
+C TODO
+C * Improve switching code, the current code sucks.
