-# Register Allocation (x64 Backend)
-
-`HostLoc`s contain values. A `HostLoc` ("host value location") is either a host CPU register or a host spill location.
-
-Values once set cannot be changed. Values can however be moved by the register allocator between `HostLoc`s. This is
-handled by the register allocator itself and code that uses the register allocator need not and should not move values
-between registers.
-
-The register allocator is based on three concepts: `Use`, `Def` and `Scratch`.
-
-* `Use`: The use of a value.
-* `Define`: The definition of a value, this is the only time when a value is set.
-* `Scratch`: Allocate a register that can be freely modified as one wishes.
-
-Note that `Use`ing a value decrements its `use_count` by one. When the `use_count` reaches zero the value is discarded and no longer exists.
-
-The member functions on `RegAlloc` are just a combination of the above concepts.
-
-The following registers are reserved for internal use and should NOT participate in register allocation:
-- `%xmm0`, `%xmm1`, `%xmm2`: Used as scratch in exclusive memory access.
-- `%rsp`: Stack pointer.
-- `%r15`: JIT pointer
-- `%r14`: Page table pointer.
-- `%r13`: Fastmem pointer.
-
-The layout convenes `%r15` as the JIT state pointer - while it may be tempting to turn it into a synthetic pointer, keeping an entire register (out of 12 available) is preferable over inlining a directly computed immediate.
-
-Do NEVER modify `%r15`, we must make it clear that this register is "immutable" for the entirety of the JIT block duration.
-
-### `Scratch`
-
-```c++
-Xbyak::Reg64 ScratchGpr(HostLocList desired_locations = any_gpr);
-Xbyak::Xmm ScratchXmm(HostLocList desired_locations = any_xmm);
-```
-
-At runtime, allocate one of the registers in `desired_locations`. You are free to modify the register. The register is discarded at the end of the allocation scope.
-
-### Pure `Use`
-
-```c++
-Xbyak::Reg64 UseGpr(Argument& arg);
-Xbyak::Xmm UseXmm(Argument& arg);
-OpArg UseOpArg(Argument& arg);
-void Use(Argument& arg, HostLoc host_loc);
-```
-
-At runtime, the value corresponding to `arg` will be placed a register. The actual register is determined by
-which one of the above functions is called. `UseGpr` places it in an unused GPR, `UseXmm` places it
-in an unused XMM register, `UseOpArg` might be in a register or might be a memory location, and `Use` allows
-you to specify a specific register (GPR or XMM) to use.
-
-This register **must not** have it's value changed.
-
-### `UseScratch`
-
-```c++
-Xbyak::Reg64 UseScratchGpr(Argument& arg);
-Xbyak::Xmm UseScratchXmm(Argument& arg);
-void UseScratch(Argument& arg, HostLoc host_loc);
-```
-
-At runtime, the value corresponding to `arg` will be placed a register. The actual register is determined by
-which one of the above functions is called. `UseScratchGpr` places it in an unused GPR, `UseScratchXmm` places it
-in an unused XMM register, and `UseScratch` allows you to specify a specific register (GPR or XMM) to use.
-
-The return value is the register allocated to you.
-
-You are free to modify the value in the register. The register is discarded at the end of the allocation scope.
-
-### `Define` as register
-
-A `Define` is the defintion of a value. This is the only time when a value may be set.
-
-```c++
-void DefineValue(IR::Inst* inst, const Xbyak::Reg& reg);
-```
-
-By calling `DefineValue`, you are stating that you wish to define the value for `inst`, and you have written the
-value to the specified register `reg`.
-
-### `Define`ing as an alias of a different value
-
-Adding a `Define` to an existing value.
-
-```c++
-void DefineValue(IR::Inst* inst, Argument& arg);
-```
-
-You are declaring that the value for `inst` is the same as the value for `arg`. No host machine instructions are
-emitted.
-
-## When to use each?
-
-* Prefer `Use` to `UseScratch` where possible.
-* Prefer the `OpArg` variants where possible.
-* Prefer to **not** use the specific `HostLoc` variants where possible.
-
-# Return Stack Buffer Optimization (x64 Backend)
-
-One of the optimizations that dynarmic does is block-linking. Block-linking is done when
-the destination address of a jump is available at JIT-time. Instead of returning to the
-dispatcher at the end of a block we can perform block-linking: just jump directly to the
-next block. This is beneficial because returning to the dispatcher can often be quite
-expensive.
-
-What should we do in cases when we can't predict the destination address? The eponymous
-example is when executing a return statement at the end of a function; the return address
-is not statically known at compile time.
-
-We deal with this by using a return stack buffer: When we execute a call instruction,
-we push our prediction onto the RSB. When we execute a return instruction, we pop a
-prediction off the RSB. If the prediction is a hit, we immediately jump to the relevant
-compiled block. Otherwise, we return to the dispatcher.
-
-This is the essential idea behind this optimization.
-
-## `UniqueHash`
-
-One complication dynarmic has is that a compiled block is not uniquely identifiable by
-the PC alone, but bits in the FPSCR and CPSR are also relevant. We resolve this by
-computing a 64-bit `UniqueHash` that is guaranteed to uniquely identify a block.
-
-```c++
-u64 LocationDescriptor::UniqueHash() const {
-    // This value MUST BE UNIQUE.
-    // This calculation has to match up with EmitX64::EmitTerminalPopRSBHint
-    u64 pc_u64 = u64(arm_pc) << 32;
-    u64 fpscr_u64 = u64(fpscr.Value());
-    u64 t_u64 = cpsr.T() ? 1 : 0;
-    u64 e_u64 = cpsr.E() ? 2 : 0;
-    return pc_u64 | fpscr_u64 | t_u64 | e_u64;
-}
-```
-
-## Our implementation isn't actually a stack
-
-Dynarmic's RSB isn't actually a stack. It was implemented as a ring buffer because
-that showed better performance in tests.
-
-### RSB Structure
-
-The RSB is implemented as a ring buffer. `rsb_ptr` is the index of the insertion
-point. Each element in `rsb_location_descriptors` is a `UniqueHash` and they
-each correspond to an element in `rsb_codeptrs`. `rsb_codeptrs` contains the
-host addresses for the corresponding the compiled blocks.
-
-`RSBSize` was chosen by performance testing. Note that this is bigger than the
-size of the real RSB in hardware (which has 3 entries). Larger RSBs than 8
-showed degraded performance.
-
-```c++
-struct JitState {
-    // ...
-
-    static constexpr size_t RSBSize = 8; // MUST be a power of 2.
-    u32 rsb_ptr = 0;
-    std::array<u64, RSBSize> rsb_location_descriptors;
-    std::array<u64, RSBSize> rsb_codeptrs;
-    void ResetRSB();
-
-    // ...
-};
-```
-
-### RSB Push
-
-We insert our prediction at the insertion point iff the RSB doesn't already
-contain a prediction with the same `UniqueHash`.

-# Fast memory (Fastmem)
-
-The main way of accessing memory in JITed programs is via an invoked function, say "Read()" and "Write()". On our translator, such functions usually take a sizable amounts of code space (push + call + pop). Trash the i-cache (due to an indirect call) and overall make code emission more bloated.
-
-The solution? Delegate invalid accesses to a dedicated arena, similar to a swap. The main idea behind such mechanism is to allow the OS to transmit page faults from invalid accesses into the JIT translator directly, bypassing address space calls, while this sacrifices i-cache coherency, it allows for smaller code-size and "faster" throguhput.
-
-Many kernels however, do not support fast signal dispatching (Solaris, OpenBSD, FreeBSD). Only Linux and Windows support relatively "fast" signal dispatching. Hence this feature is better suited for them only.
-
-![Host to guest translation](./HostToGuest.svg)
-
-![Fastmem translation](./Fastmem.svg)
-
-In x86_64 for example, when a page fault occurs, the CPU will transmit via control registers and the stack (see `IRETQ`) the appropriate arguments for a page fault handler, the OS then will transform that into something that can be sent into userspace.
-
-Most modern OSes implement kernel-page-table-isolation, which means a set of system calls will invoke a context switch (not often used syscalls), whereas others are handled by the same process address space (the smaller kernel portion, often used syscalls) without needing a context switch.

+# Fast memory (Fastmem)
+
+The main way of accessing memory in JITed programs is via an invoked function, say "Read()" and "Write()". On our translator, such functions usually take a sizable amounts of code space (push + call + pop). Trash the i-cache (due to an indirect call) and overall make code emission more bloated.
+
+The solution? Delegate invalid accesses to a dedicated arena, similar to a swap. The main idea behind such mechanism is to allow the OS to transmit page faults from invalid accesses into the JIT translator directly, bypassing address space calls, while this sacrifices i-cache coherency, it allows for smaller code-size and "faster" throguhput.
+
+Many kernels however, do not support fast signal dispatching (Solaris, OpenBSD, FreeBSD). Only Linux and Windows support relatively "fast" signal dispatching. Hence this feature is better suited for them only.
+
+![Host to guest translation](./HostToGuest.svg)
+
+![Fastmem translation](./Fastmem.svg)
+
+In x86_64 for example, when a page fault occurs, the CPU will transmit via control registers and the stack (see `IRETQ`) the appropriate arguments for a page fault handler, the OS then will transform that into something that can be sent into userspace.
+
+Most modern OSes implement kernel-page-table-isolation, which means a set of system calls will invoke a context switch (not often used syscalls), whereas others are handled by the same process address space (the smaller kernel portion, often used syscalls) without needing a context switch. This effect can be negated on systems with PCID (up to 4096 unique IDs).

+# Register Allocation (x64 Backend)
+
+`HostLoc`s contain values. A `HostLoc` ("host value location") is either a host CPU register or a host spill location.
+
+Values once set cannot be changed. Values can however be moved by the register allocator between `HostLoc`s. This is
+handled by the register allocator itself and code that uses the register allocator need not and should not move values
+between registers.
+
+The register allocator is based on three concepts: `Use`, `Def` and `Scratch`.
+
+* `Use`: The use of a value.
+* `Define`: The definition of a value, this is the only time when a value is set.
+* `Scratch`: Allocate a register that can be freely modified as one wishes.
+
+Note that `Use`ing a value decrements its `use_count` by one. When the `use_count` reaches zero the value is discarded and no longer exists.
+
+The member functions on `RegAlloc` are just a combination of the above concepts.
+
+The following registers are reserved for internal use and should NOT participate in register allocation:
+- `%xmm0`, `%xmm1`, `%xmm2`: Used as scratch in exclusive memory access.
+- `%rsp`: Stack pointer.
+- `%r15`: JIT pointer
+- `%r14`: Page table pointer.
+- `%r13`: Fastmem pointer.
+
+The layout convenes `%r15` as the JIT state pointer - while it may be tempting to turn it into a synthetic pointer, keeping an entire register (out of 12 available) is preferable over inlining a directly computed immediate.
+
+Do NEVER modify `%r15`, we must make it clear that this register is "immutable" for the entirety of the JIT block duration.
+
+### `Scratch`
+
+```c++
+Xbyak::Reg64 ScratchGpr(HostLocList desired_locations = any_gpr);
+Xbyak::Xmm ScratchXmm(HostLocList desired_locations = any_xmm);
+```
+
+At runtime, allocate one of the registers in `desired_locations`. You are free to modify the register. The register is discarded at the end of the allocation scope.
+
+### Pure `Use`
+
+```c++
+Xbyak::Reg64 UseGpr(Argument& arg);
+Xbyak::Xmm UseXmm(Argument& arg);
+OpArg UseOpArg(Argument& arg);
+void Use(Argument& arg, HostLoc host_loc);
+```
+
+At runtime, the value corresponding to `arg` will be placed a register. The actual register is determined by
+which one of the above functions is called. `UseGpr` places it in an unused GPR, `UseXmm` places it
+in an unused XMM register, `UseOpArg` might be in a register or might be a memory location, and `Use` allows
+you to specify a specific register (GPR or XMM) to use.
+
+This register **must not** have it's value changed.
+
+### `UseScratch`
+
+```c++
+Xbyak::Reg64 UseScratchGpr(Argument& arg);
+Xbyak::Xmm UseScratchXmm(Argument& arg);
+void UseScratch(Argument& arg, HostLoc host_loc);
+```
+
+At runtime, the value corresponding to `arg` will be placed a register. The actual register is determined by
+which one of the above functions is called. `UseScratchGpr` places it in an unused GPR, `UseScratchXmm` places it
+in an unused XMM register, and `UseScratch` allows you to specify a specific register (GPR or XMM) to use.
+
+The return value is the register allocated to you.
+
+You are free to modify the value in the register. The register is discarded at the end of the allocation scope.
+
+### `Define` as register
+
+A `Define` is the defintion of a value. This is the only time when a value may be set.
+
+```c++
+void DefineValue(IR::Inst* inst, const Xbyak::Reg& reg);
+```
+
+By calling `DefineValue`, you are stating that you wish to define the value for `inst`, and you have written the
+value to the specified register `reg`.
+
+### `Define`ing as an alias of a different value
+
+Adding a `Define` to an existing value.
+
+```c++
+void DefineValue(IR::Inst* inst, Argument& arg);
+```
+
+You are declaring that the value for `inst` is the same as the value for `arg`. No host machine instructions are
+emitted.
+
+## When to use each?
+
+* Prefer `Use` to `UseScratch` where possible.
+* Prefer the `OpArg` variants where possible.
+* Prefer to **not** use the specific `HostLoc` variants where possible.

+# Return Stack Buffer Optimization (x64 Backend)
+
+One of the optimizations that dynarmic does is block-linking. Block-linking is done when
+the destination address of a jump is available at JIT-time. Instead of returning to the
+dispatcher at the end of a block we can perform block-linking: just jump directly to the
+next block. This is beneficial because returning to the dispatcher can often be quite
+expensive.
+
+What should we do in cases when we can't predict the destination address? The eponymous
+example is when executing a return statement at the end of a function; the return address
+is not statically known at compile time.
+
+We deal with this by using a return stack buffer: When we execute a call instruction,
+we push our prediction onto the RSB. When we execute a return instruction, we pop a
+prediction off the RSB. If the prediction is a hit, we immediately jump to the relevant
+compiled block. Otherwise, we return to the dispatcher.
+
+This is the essential idea behind this optimization.
+
+## `UniqueHash`
+
+One complication dynarmic has is that a compiled block is not uniquely identifiable by
+the PC alone, but bits in the FPSCR and CPSR are also relevant. We resolve this by
+computing a 64-bit `UniqueHash` that is guaranteed to uniquely identify a block.
+
+```c++
+u64 LocationDescriptor::UniqueHash() const {
+    // This value MUST BE UNIQUE.
+    // This calculation has to match up with EmitX64::EmitTerminalPopRSBHint
+    u64 pc_u64 = u64(arm_pc) << 32;
+    u64 fpscr_u64 = u64(fpscr.Value());
+    u64 t_u64 = cpsr.T() ? 1 : 0;
+    u64 e_u64 = cpsr.E() ? 2 : 0;
+    return pc_u64 | fpscr_u64 | t_u64 | e_u64;
+}
+```
+
+## Our implementation isn't actually a stack
+
+Dynarmic's RSB isn't actually a stack. It was implemented as a ring buffer because
+that showed better performance in tests.
+
+### RSB Structure
+
+The RSB is implemented as a ring buffer. `rsb_ptr` is the index of the insertion
+point. Each element in `rsb_location_descriptors` is a `UniqueHash` and they
+each correspond to an element in `rsb_codeptrs`. `rsb_codeptrs` contains the
+host addresses for the corresponding the compiled blocks.
+
+`RSBSize` was chosen by performance testing. Note that this is bigger than the
+size of the real RSB in hardware (which has 3 entries). Larger RSBs than 8
+showed degraded performance.
+
+```c++
+struct JitState {
+    // ...
+
+    static constexpr size_t RSBSize = 8; // MUST be a power of 2.
+    u32 rsb_ptr = 0;
+    std::array<u64, RSBSize> rsb_location_descriptors;
+    std::array<u64, RSBSize> rsb_codeptrs;
+    void ResetRSB();
+
+    // ...
+};
+```
+
+### RSB Push
+
+We insert our prediction at the insertion point iff the RSB doesn't already
+contain a prediction with the same `UniqueHash`.
+
+```c++
+void EmitX64::EmitPushRSB(IR::Block&, IR::Inst* inst) {
+    using namespace Xbyak::util;
+

+                    ? u64(unique_hash_to_code_ptr[imm64])
+                    : u64(code->GetReturnFromRunCodeAddress());
+
+    code->mov(index_reg, dword[code.ABI_JIT_PTR + offsetof(JitState, rsb_ptr)]);
+    code->add(index_reg, 1);
+    code->and_(index_reg, u32(JitState::RSBSize - 1));
+
+    code->mov(loc_desc_reg, u64(imm64));
+    CodePtr patch_location = code->getCurr<CodePtr>();
+    patch_unique_hash_locations[imm64].emplace_back(patch_location);
+    code->mov(code_ptr_reg, u64(code_ptr)); // This line has to match up with EmitX64::Patch.
+    code->EnsurePatchLocationSize(patch_location, 10);
+
+    Xbyak::Label label;
+    for (size_t i = 0; i < JitState::RSBSize; ++i) {

+    }

+    code->mov(qword[code.ABI_JIT_PTR + index_reg.cvt64() * 8 + offsetof(JitState, rsb_codeptrs)], code_ptr_reg);
+    code->L(label);
+}
+```
+
+In pseudocode:
+
+```c++
+    for (i := 0 .. RSBSize-1)
+        if (rsb_location_descriptors[i] == imm64)
+        goto label;
+    rsb_ptr++;
+    rsb_ptr %= RSBSize;

+    rsb_codeptr[rsb_ptr] = /* codeptr corresponding to the UniqueHash */;
+label:
+```
+
+## RSB Pop
+
+To check if a predicition is in the RSB, we linearly scan the RSB.
+
+```c++
+void EmitX64::EmitTerminalPopRSBHint(IR::Term::PopRSBHint, IR::LocationDescriptor initial_location) {
+    using namespace Xbyak::util;

+        code->cmove(rax, qword[code.ABI_JIT_PTR + offsetof(JitState, rsb_codeptrs) + i * sizeof(u64)]);
+    }
+
+    code->jmp(rax);

+```
+
+In pseudocode:
