+/*
+ * Welcome to FEX-Emu's custom AArch64 emitter.
+ * This was written specifically to avoid the performance cost of the vixl emitter.
+ *
+ * There are some specific design constraints in this design to target a couple features:
+ *   - High performance
+ *   - Low CPU cache performance hit
+ *   - Significantly reduced code footprint
+ *   - Low number of branches
+ *
+ * These requirements are mostly achieved by removing a bunch of developer conveniences
+ * that vixl provides. The developer needs to take a lot of care to not shoot themselves in the foot.
+ *
+ * Misc design decisions:
+ * - Registers are encoded as basic uint32_t enums.
+ *   - Converting between different registers is zero-cost.
+ *   - Passing around as arguments are as cheap as registers
+ *     - Contrast to vixl where every register requires living on the stack.
+ *   - Registers can get encoded in to instructions with a simple `BFM` instruction.
+ *
+ * - Instructions are very simply emitted, allowing direct inlining most of the time.
+ *   - These are simple enough that multiple back-to-back instructions get optimized to 128-bit load-store operations.
+ *     - Contrast to vixl where pretty much no instruction emitter gets inlined.
+ *
+ * - Instruction emitters are /mostly/ unsized. Most instructions take a size argument first, which gets encoded
+ *   directly in to the instruction.
+ *   - Contrast to vixl where the register arguments are how the instructions determine operating size.
+ *   - Size argument allows FEX to use `CSEL` to select a size at runtime, instead of branching.
+ *   - Some instructions are explicitly sized based on register type. Read comments in the respective `inl` files to
+ *     see why.
+ *     Some scalar/vector operations are an example of this.
+ *
+ * - Almost zero helper functions.
+ *   - Primary exception to this rule is load-store operations. These will use a helper to make
+ *     it easier to select the correct load-store instruction. Mostly because these are a nightmare selecting
+ *     the right instruction.
