Add an early TailMerge pass (#2721)
* Add an early `TailMerge` pass

Some translations can have a lot of guest calls and since for each guest
call there is a call guard which may return. This can produce a lot of
epilogue code for returns. This pass merges the epilogue into a single
block.

Optimize LSRA (#2563)
* Optimize `TryAllocateRegWithtoutSpill` a bit

* Add a fast path for when all registers are live.
* Do not query `GetOverlapPosition` if the register is already in use
  (i.e: free position is 0).

* Do not allocate child split list if not parent

* Turn `LiveRange` into a reference struct

`LiveRange` is now a reference wrapping struct like `Operand` and
`Operation`.

It has also been changed into a singly linked-list. In micro-benchmarks
traversing the linked-list was faster than binary search on `List<T>`.
Even for quite large input sizes (e.g: 1,000,000), surprisingly.

Could be because the code gen for traversing the linked-list is much
much cleaner and there is no virtual dispatch happening when checking if
intervals overlaps.

* Turn `LiveInterval` into an iterator

The LSRA allocates in forward order and never inspect previous
`LiveInterval` once they are expired. Something similar can be done for
the `LiveRange`s within the `LiveInterval`s themselves.

The `LiveInterval` is turned into a iterator which expires `LiveRange`
within it. The iterator is moved forward along with interval walking
code, i.e: AllocateInterval(context, interval, cIndex).

* Remove `LinearScanAllocator.Sources`

Local methods are less susceptible to do allocations than lambdas.

* Optimize `GetOverlapPosition(interval)` a bit

Time complexity should be in O(n+m) instead of O(nm) now.

* Optimize `NumberLocals` a bit

Use the same idea as in `HybridAllocator` to store the visited state
in the MSB of the Operand's value instead of using a `HashSet<T>`.

* Optimize `InsertSplitCopies` a bit

Avoid allocating a redundant `CopyResolver`.

* Optimize `InsertSplitCopiesAtEdges` a bit

Avoid redundant allocations of `CopyResolver`.

* Use stack allocation for `freePositions`

Avoid redundant computations.

* Add `UseList`

Replace `SortedIntegerList` with an even more specialized data
structure. It allocates memory on the arena allocators and does not
require copying use positions when splitting it.

* Turn `LiveInterval` into a reference struct

`LiveInterval` is now a reference wrapping struct like `Operand` and
`Operation`.

The rationale behind turning this in a reference wrapping struct is
because a `LiveInterval` is associated with each local variable, and
these intervals may themselves be split further. I've seen translations
having up to 8000 local variables.

To make the `LiveInterval` unmanaged, a new data structure called
`LiveIntervalList` was added to store child splits. This differs from
`SortedList<,>` because it can contain intervals with the same start
position.

Really wished we got some more of C++ template in C#. :^(

* Optimize `GetChildSplit` a bit

No need to inspect the remaining ranges if we've reached a range which
starts after position, since the split list is ordered.

* Optimize `CopyResolver` a bit

Lazily allocate the fill, spill and parallel copy structures since most
of the time only one of them is needed.

* Optimize `BitMap.Enumerator` a bit

Marking `MoveNext` as `AggressiveInlining` allows RyuJIT to promote the
`Enumerator` struct into registers completely, reducing load/store code
a lot since it does not have to store the struct on the stack for ABI
purposes.

* Use stack allocation for `use/blockedPositions`

* Optimize `AllocateWithSpill` a bit

* Address feedback

* Make `LiveInterval.AddRange(,)` more conservative

Produces no diff against master, but just for good measure.

Replace CacheResourceWrite with more general "precise" write (#2684)
* Replace CacheResourceWrite with more general "precise" write

The goal of CacheResourceWrite was to notify GPU resources when they were modified directly, by looking up the modified address/size in a structure and calling a method on each resource. The downside of this is that each resource cache has to be queried individually, they all have to implement their own way to do this, and it can only signal to resources using the same PhysicalMemory instance.

This PR adds the ability to signal a write as "precise" on the tracking, which signals a special handler (if present) which can be used to avoid unnecessary flush actions, or maybe even more. For buffers, precise writes specifically do not flush, and instead punch a hole in the modified range list to indicate that the data on GPU has been replaced.

The downside is that precise actions must ignore the page protection bits and always signal - as they need to notify the target resource to ignore the sequence number optimization.

I had to reintroduce the sequence number increment after I2M, as removing it was causing issues in rabbids kingdom battle. However - all resources modified by I2M are notified directly to lower their sequence number, so the problem is likely that another unrelated resource is not being properly updated. Thankfully, doing this does not affect performance in the games I tested.

This should fix regressions from #2624. Test any games that were broken by that. (RF4, rabbids kingdom battle)

I've also added a sequence number increment to ThreedClass.IncrementSyncpoint, as it seems to fix buffer corruption in OpenGL homebrew. (this was a regression from removing sequence number increment from constant buffer update - another unrelated resource thing)

* Add tests.

* Add XML docs for GpuRegionHandle

* Skip UpdateProtection if only precise actions were called

This allows precise actions to skip reprotection costs.

Optimize HybridAllocator (#2637)
* Store constant `Operand`s in the `LocalInfo`

Since the spill slot and register assigned is fixed, we can just store
the `Operand` reference in the `LocalInfo` struct. This allows skipping
hitting the intern-table for a look up.

* Skip `Uses`/`Assignments` management

Since the `HybridAllocator` is the last pass and we do not care about
uses/assignments we can skip managing that when setting destinations or
sources.

* Make `GetLocalInfo` inlineable

Also fix a possible issue where with numbered locals. See or-assignment
operator in `SetVisited(local)` before patch.

* Do not run `BlockPlacement` in LCQ

With the host mapped memory manager, there is a lot less cold code to
split from hot code. So disabling this in LCQ gives some extra
throughput - where we need it.

Fix PTC count table relocation patching (#2666)
Fix an issue introduced in #2190 where by 2 different count table entry
addresses were used for LCQ functions. E.g:

```asm
 .L1:
   mov rbp,COUNT_TABLE_0   ;; This gets an address.
   mov ebp,[rbp]
   lea esi,[rbp+1]
   mov rdi,COUNT_TABLE_1   ;; This gets another address.
   mov [rdi],esi
   cmp ebp,64h
   je near .L34
```

This caused LCQ functions to not tier up when they're loaded from the
PTC cache. This does not happen when they're freshly compiled.

This PR fixes the issue by ensuring only a single counter is created per
translation.

Refactor PtcInfo (#2625)
* Refactor `PtcInfo`

This change reduces the coupling of `PtcInfo` by moving relocation
tracking to the backend. `RelocEntry`s remains as `RelocEntry`s through
out the pipeline until it actually needs to be written to the PTC
streams. Keeping this representation makes inspecting and manipulating
relocations after compilations less painful. This is something I needed
to do to patch relocations to 0 to diff dumps.

Contributes to #1125.

* Turn `Symbol` & `RelocInfo` into readonly structs

Fix type mismatch in BitwiseAnd simplification (#2571)
* Fix type mismatch in `BitwiseAnd` simplification

`TryEliminateBitwiseAnd` would turn the `BitwiseAnd` operation into a
copy of the wrong type. E.g:

Before `Simplification`:
```llvm
i64 %0 = BitwiseAnd i64 0x0, %1
```

After `Simplication`:
```llvm
i64 %0 = Copy i32 0x0
```

Since the with the changes in #2515, we iterate in reverse order and
`Simplication`, `ConstantFolding` does not indicate if it modified
the CFG, the second pass to "retype" the copy into the proper
destination type does not happen.

This also blocked copy propagation since its destination type did not
match with its source type. But in the cases I've seen, the
`PreAllocator` would insert a copy for the propagated constant, which
results in no diffs.

Since the copy remained as is, asserts are fired when generating it.

* Fix PPTC symbols

* Optimize `BasicBlock` a bit

Reduce allocations from `_successor` & `DominanceFrontiers`

* Fix `Operation` resize

* Make `Arena` expandable

Change the arena allocator to be expandable by allocating in pages, with
some of them being pooled. Currently 32 pages are pooled. An LRU removal
mechanism should probably be added to it.

Apparently MHR can allocate bitmaps large enough to exceed the 16MB
limit for the type.

* Move `Arena` & `ArenaList` to `Common`

* Remove `ThreadStaticPool` & co

* Add `PhiOperation`

* Reduce `Operand` size from 56 from 48 bytes

* Add linear-probing to `Operand` intern table

* Optimize `HybridAllocator` a bit

* Add `Allocators` class

* Tune `ArenaAllocator` sizes

* Add page removal mechanism to `ArenaAllocator`

Remove pages which have not been used for more than 5s after each reset.

I am on fence if this would be better using a Gen2 callback object like
the one in System.Buffers.ArrayPool<T>, to trim the pool. Because right
now if a large translation happens, the pages will be freed only after a
reset. This reset may not happen for a while because no new translation
is hit, but the arena base sizes are rather small.

* Fix `OOM` when allocating larger than page size in `ArenaAllocator`

Tweak resizing mechanism for Operand.Uses and Assignemnts.

* Optimize `Optimizer` a bit

* Optimize `Operand.Add<T>/Remove<T>` a bit

* Clean up `PreAllocator`

* Fix phi insertion order

Reduce codegen diffs.

* Fix code alignment

* Use new heuristics for degree of parallelism

* Suppress warnings

* Address gdkchan's feedback

Renamed `GetValue()` to `GetValueUnsafe()` to make it more clear that
`Operand.Value` should usually not be modified directly.

* Add fast path to `ArenaAllocator`

* Assembly for `ArenaAllocator.Allocate(ulong)`:

  .L0:
    mov rax, [rcx+0x18]
    lea r8, [rax+rdx]
    cmp r8, [rcx+0x10]
    ja short .L2
  .L1:
    mov rdx, [rcx+8]
    add rax, [rdx+8]
    mov [rcx+0x18], r8
    ret
  .L2:
    jmp ArenaAllocator.AllocateSlow(UInt64)

  A few variable/field had to be changed to ulong so that RyuJIT avoids
  emitting zero-extends.

* Implement a new heuristic to free pooled pages.

  If an arena is used often, it is more likely that its pages will be
  needed, so the pages are kept for longer (e.g: during PPTC rebuild or
  burst sof compilations). If is not used often, then it is more likely
  that its pages will not be needed (e.g: after PPTC rebuild or bursts
  of compilations).

* Address riperiperi's feedback

* Use `EqualityComparer<T>` in `IntrusiveList<T>`

Avoids a potential GC hole in `Equals(T, T)`.

This is to reduce the impact this change has on the test duration.
Before everytime a test was ran, the FunctionTable would be initialized
and populated so that the newly compiled test would get registered to
it.

Uses the DispatchStub to dispatch into the next translation, which
allows execution to stay in unmanaged for longer and skips a
ConcurrentDictionary look up when the target translation has been
registered to the FunctionTable.

Uses 5 levels instead of 4 and change unit of AddressTableEventSource
from KB to MB.

* Use 64-bit function table

    mov qword [rax+0x408],0x10603560
 -  mov rcx,sub_10603560_OFFSET
 -  mov ecx,[rcx]
 -  mov ecx,ecx
 -  mov rdx,JIT_CACHE_BASE
 -  add rdx,rcx
 +  mov rcx,sub_10603560
 +  mov rdx,[rcx]
    mov rcx,rax

Improves codegen for dispatch stub:

    and rax,byte +0x1f
 -  mov eax,[rcx+rax*4]
 -  mov eax,eax
 -  mov rcx,JIT_CACHE_BASE
 -  lea rax,[rcx+rax]
 +  mov rax,[rcx+rax*8]
    mov rcx,rbx

* Remove `JitCacheSymbol` & `JitCache.Offset`

* Turn `Translator.Translate` into an instance method

We do not have to add more parameter to this method and related ones as
new structures are added & needed for translation.

* Add symbol only when PTC is enabled

Address LDj3SNuD's feedback

* Change `NativeContext.Running` to a 32-bit integer

POWER - Performance Optimizations With Extensive Ramifications (#2286)
* Refactoring of KMemoryManager class

* Replace some trivial uses of DRAM address with VA

* Get rid of GetDramAddressFromVa

* Abstracting more operations on derived page table class

* Run auto-format on KPageTableBase

* Managed to make TryConvertVaToPa private, few uses remains now

* Implement guest physical pages ref counting, remove manual freeing

* Make DoMmuOperation private and call new abstract methods only from the base class

* Pass pages count rather than size on Map/UnmapMemory

* Change memory managers to take host pointers

* Fix a guest memory leak and simplify KPageTable

* Expose new methods for host range query and mapping

* Some refactoring of MapPagesFromClientProcess to allow proper page ref counting and mapping without KPageLists

* Remove more uses of AddVaRangeToPageList, now only one remains (shared memory page checking)

* Add a SharedMemoryStorage class, will be useful for host mapping

* Sayonara AddVaRangeToPageList, you served us well

* Start to implement host memory mapping (WIP)

* Support memory tracking through host exception handling

* Fix some access violations from HLE service guest memory access and CPU

* Fix memory tracking

* Fix mapping list bugs, including a race and a error adding mapping ranges

* Simple page table for memory tracking

* Simple "volatile" region handle mode

* Update UBOs directly (experimental, rough)

* Fix the overlap check

* Only set non-modified buffers as volatile

* Fix some memory tracking issues

* Fix possible race in MapBufferFromClientProcess (block list updates were not locked)

* Write uniform update to memory immediately, only defer the buffer set.

* Fix some memory tracking issues

* Pass correct pages count on shared memory unmap

* Armeilleure Signal Handler v1 + Unix changes

Unix currently behaves like windows, rather than remapping physical

* Actually check if the host platform is unix

* Fix decommit on linux.

* Implement windows 10 placeholder shared memory, fix a buffer issue.

* Make PTC version something that will never match with master

* Remove testing variable for block count

* Add reference count for memory manager, fix dispose

Can still deadlock with OpenAL

* Add address validation, use page table for mapped check, add docs

Might clean up the page table traversing routines.

* Implement batched mapping/tracking.

* Move documentation, fix tests.

* Cleanup uniform buffer update stuff.

* Remove unnecessary assignment.

* Add unsafe host mapped memory switch

On by default. Would be good to turn this off for untrusted code (homebrew, exefs mods) and give the user the option to turn it on manually, though that requires some UI work.

* Remove C# exception handlers

They have issues due to current .NET limitations, so the meilleure one fully replaces them for now.

* Fix MapPhysicalMemory on the software MemoryManager.

* Null check for GetHostAddress, docs

* Add configuration for setting memory manager mode (not in UI yet)

* Add config to UI

* Fix type mismatch on Unix signal handler code emit

* Fix 6GB DRAM mode.

The size can be greater than `uint.MaxValue` when the DRAM is >4GB.

* Address some feedback.

* More detailed error if backing memory cannot be mapped.

* SetLastError on all OS functions for consistency

* Force pages dirty with UBO update instead of setting them directly.

Seems to be much faster across a few games. Need retesting.

* Rebase, configuration rework, fix mem tracking regression

* Fix race in FreePages

* Set memory managers null after decrementing ref count

* Remove readonly keyword, as this is now modified.

* Use a local variable for the signal handler rather than a register.

* Fix bug with buffer resize, and index/uniform buffer binding.

Should fix flickering in games.

* Add InvalidAccessHandler to MemoryTracking

Doesn't do anything yet

* Call invalid access handler on unmapped read/write.

Same rules as the regular memory manager.

* Make unsafe mapped memory its own MemoryManagerType

* Move FlushUboDirty into UpdateState.

* Buffer dirty cache, rather than ubo cache

Much cleaner, may be reusable for Inline2Memory updates.

* This doesn't return anything anymore.

* Add sigaction remove methods, correct a few function signatures.

* Return empty list of physical regions for size 0.

* Also on AddressSpaceManager

Use a branch instead of doing a tailcall for recursive calls. This
avoids having to store the dispatch address, setting up the epilogue and
keeps guest registers in host registers for longer.

The rejit check is moved down into the entry block so that the rejit
behaviour remains the same as before.

Fix LiveInterval.Split (#1660)
Before when splitting intervals, the end of the range would be included
in the split check, this can produce empty ranges in the child split.

This in turn can affect spilling decisions since the child split will
have a different start position and this empty range will get a register
and move to the active set for a brief moment.

For example:

  A = [153, 172[; [1899, 1916[; [1991, 2010[; [2397, 2414[; ...

  Split(A, 1916)

  A0 = [153, 172[; [1899, 1916[
  A1 = [1916, 1916[; [1991, 2010[; [2397, 2414[; ...

Memory Read/Write Tracking using Region Handles (#1272)
* WIP Range Tracking

- Texture invalidation seems to have large problems
- Buffer/Pool invalidation may have problems
- Mirror memory tracking puts an additional `add` in compiled code, we likely just want to make HLE access slower if this is the final solution.
- Native project is in the messiest possible location.
- [HACK] JIT memory access always uses native "fast" path
- [HACK] Trying some things with texture invalidation and views.

It works :)

Still a few hacks, messy things, slow things

More work in progress stuff (also move to memory project)

Quite a bit faster now.
- Unmapping GPU VA and CPU VA will now correctly update write tracking regions, and invalidate textures for the former.
- The Virtual range list is now non-overlapping like the physical one.
- Fixed some bugs where regions could leak.
- Introduced a weird bug that I still need to track down (consistent invalid buffer in MK8 ribbon road)

Move some stuff.

I think we'll eventually just put the dll and so for this in a nuget package.

Fix rebase.

[WIP] MultiRegionHandle variable size ranges

- Avoid reprotecting regions that change often (needs some tweaking)
- There's still a bug in buffers, somehow.
- Might want different api for minimum granularity

Fix rebase issue

Commit everything needed for software only tracking.

Remove native components.

Remove more native stuff.

Cleanup

Use a separate window for the background context, update opentk. (fixes linux)

Some experimental changes

Should get things working up to scratch - still need to try some things with flush/modification and res scale.

Include address with the region action.

Initial work to make range tracking work

Still a ton of bugs

Fix some issues with the new stuff.

* Fix texture flush instability

There's still some weird behaviour, but it's much improved without this. (textures with cpu modified data were flushing over it)

* Find the destination texture for Buffer->Texture full copy

Greatly improves performance for nvdec videos (with range tracking)

* Further improve texture tracking

* Disable Memory Tracking for view parents

This is a temporary approach to better match behaviour on master (where invalidations would be soaked up by views, rather than trigger twice)

The assumption is that when views are created to a texture, they will cover all of its data anyways. Of course, this can easily be improved in future.

* Introduce some tracking tests.

WIP

* Complete base tests.

* Add more tests for multiregion, fix existing test.

* Cleanup Part 1

* Remove unnecessary code from memory tracking

* Fix some inconsistencies with 3D texture rule.

* Add dispose tests.

* Use a background thread for the background context.

Rather than setting and unsetting a context as current, doing the work on a dedicated thread with signals seems to be a bit faster.

Also nerf the multithreading test a bit.

* Copy to texture with matching alignment

This extends the copy to work for some videos with unusual size, such as tutorial videos in SMO. It will only occur if the destination texture already exists at XCount size.

* Track reads for buffer copies. Synchronize new buffers before copying overlaps.

* Remove old texture flushing mechanisms.

Range tracking all the way, baby.

* Wake the background thread when disposing.

Avoids a deadlock when games are closed.

* Address Feedback 1

* Separate TextureCopy instance for background thread

Also `BackgroundContextWorker.InBackground` for a more sensible idenfifier for if we're in a background thread.

* Add missing XML docs.

* Address Feedback

* Maybe I should start drinking coffee.

* Some more feedback.

* Remove flush warning, Refocus window after making background context

Before `block.Next` had to follow `block.ListNext`, now it does not.
