+/* You may be asking why I hard-code the instruction opcodes and don't
+ * use the normal VIS assembler mnenomics for the VIS instructions.
+ *
+ * The reason is that Sun, in their infinite wisdom, decided that a binary
+ * using a VIS instruction will cause it to be marked (in the ELF headers)
+ * as doing so, and this prevents the OS from loading such binaries if the
+ * current cpu doesn't have VIS.  There is no way to easily override this
+ * behavior of the assembler that I am aware of.
+ *
+ * This totally defeats what libmpeg2 is trying to do which is allow a
+ * single binary to be created, and then detect the availability of VIS
+ * at runtime.
+ *
+ * I'm not saying that tainting the binary by default is bad, rather I'm
+ * saying that not providing a way to override this easily unnecessarily
+ * ties people's hands.
+ *
+ * Thus, we do the opcode encoding by hand and output 32-bit words in
+ * the assembler to keep the binary from becoming tainted.
