generator.h used to be the implementation of Holger Bettag's 65536+
generated Altivec constants, although I've pared it down to just
combinations of 2 VPERM opcodes to avoid overloading the compiler. In
the end the file is still pretty large and tends to slow down
compilation a lot, so I fenced it with #ifndef NDEBUG for developers
who want that extra performance.
In the (short) future I'll be splitting it into generator_altivec.h
and generator_mmx.h and putting some generated MMX/SSE constants into
Cheers, Glen Low
