 ### Target Host Architecture
 The target host architecture for this library is AArch64. Specifically the ARMv8.1 version or newer.
-The CPU IR is designed with AArch64 in mind but there is a desire to run the recompiled code on other architectures as well.
-Multiple architecture support is desired for easier bringup and debugging, performance isn't as much of a priority there (ex. x86-64(guest) translated to x86-64(host))
-### Not currently goals but will be in the future
-* 32bit x86 support
-  * This will be a desire in the future, but to lower the amount of work required, decided to push this off for now.
-* Integration in to WINE
-* Later generation of x86-64 instruction sets
-  * Including AVX, F16C, XOP, FMA, AVX2, etc
