/* 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.
