    v1 v2  
    5555 * On the x86_64 architecture, there are 4 Float registers and 2 Double registers.  These actually use the `xmm` registers, so there are only two left to use as packed registers.  My current solution is to reduce the Float registers to 3 so that there are 3 `xmm` registers. 
    5656 * SSE4 capable CPUs have 16 `xmm` registers, but I am unsure as to how to approach checking for these extra registers, since the registers to use are hard coded in C.
