The swizzle instruction is very powerful in that in can do any of the 256 permutations of xyzw, optionally negate any combination of the resulting components, and zero any combination of the result components (even all). This means the one instruction can take care of any actual swizzles, conjugation for complex and quaternion values, zeroing vectors (not that it's the only way), and probably other weird things. The python file was used to generate the jump table and actual swizzle code. |
