Working on [Bug 602 - low performance bare minimum functionality SIMD emulator required][bug 602] pulling pseudocode out of documentation to make a VSX implementation in software. Based on the ISA spec. v3.0B:
-1. pp. 246 to 252, vector pack/unpack
+1. pp. 246 to 252, vector pack/unpack (Looks like section 6.8 "Vector Permute and Formatting Instructions", subsection 6.8.1 "Vector Pack and Unpack Instructions" actually appears on pages labeled 248-254 which are actually pages 266-272)
