* Add optimistic interning of Register & Constant operands
* Optimize `RegisterUsage` pass a bit
* Optimize `RemoveUnusedNodes` pass a bit
Iterating in reverse-order allows killing dependency chains in a single

* 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)`.
* Changes to allow explicit management of service threads
* Remove now unused code
* Remove ThreadCounter, its no longer needed
* Allow and use separate server per service, also fix exit issues
* New policy change: PTC version now uses PR number
* Generalize tail continues
* Fix DecodeBasicBlock
`Next` and `Branch` would be null, which is not the state expected by
the branch instructions. They end up branching or falling into a block
which is never populated by the `Translator`. This causes an assert to
be fired when building the CFG.
* Clean up Decode overloads
* Do not synchronize when branching into exit block
If we're branching into an exit block, that exit block will tail
continue into another translation which already has a synchronization.
* Remove A32 predicate tail continue
If `block` is not an exit block then the `block.Next` must exist (as
per the last instruction of `block`).
* Throw if decoded 0 blocks

* Implement Jump Table for Native Calls
NOTE: this slows down rejit considerably! Not recommended to be used
without codegen optimisation or AOT.
- Does not work on Linux
- A32 needs an additional commit.
* A32 Support
(WIP)
* Actually write Direct Call pointers to the table
That would help.
* Direct Calls: Rather than returning to the translator, attempt to keep within the native stack frame.
A return to the translator can still happen, but only by exceptionally
bubbling up to it.
Also:
- Always translate lowCq as a function. Faster interop with the direct
jumps, and this will be useful in future if we want to do speculative
translation.
- Tail Call Detection: after the decoding stage, detect if we do a tail
call, and avoid translating into it. Detected if a jump is made to an
address outwith the contiguous sequence of blocks surrounding the entry
point. The goal is to reduce code touched by jit and rejit.
* A32 Support
* Use smaller max function size for lowCq, fix exceptional returns
When a return has an unexpected value and there is no code block
following this one, we now return the value rather than continuing.
* CompareAndSwap (buggy)
* Ensure CompareAndSwap does not get optimized away.
* Use CompareAndSwap to make the dynamic table thread safe.
* Tail call for linux, throw on too many arguments.
* Combine CompareAndSwap 128 and 32/64.
They emit different IR instructions since their PreAllocator behaviour
is different, but now they just have one function on EmitterContext.
* Fix issues separating from optimisations.
* Use a stub to find and execute missing functions.
This allows us to skip doing many runtime comparisons and branches, and reduces the amount of code we need to emit significantly.
For the indirect call table, this stub also does the work of moving in the highCq address to the table when one is found.
* Make Jump Tables and Jit Cache dynmically resize
Reserve virtual memory, commit as needed.
* Move TailCallRemover to its own class.
* Multithreaded Translation (based on heuristic)
A poor one, at that. Need to get core count for a better one, which
means a lot of OS specific garbage.
* Better priority management for background threads.
* Bound core limit a bit more
Past a certain point the load is not paralellizable and starts stealing from the main thread. Likely due to GC, memory, heap allocation thread contention. Reduce by one core til optimisations come to improve the situation.
* Fix memory management on linux.
* Temporary solution to some sync problems.
This will make sure threads exit correctly, most of the time. There is a potential race where setting the sync counter to 0 does nothing (counter stays at what it was before, thread could take too long to exit), but we need to find a better way to do this anyways. Synchronization frequency has been tightened as we never enter blockwise segments of code. Essentially this means, check every x functions or loop iterations, before lowcq blocks existed and were worth just as much. Ideally it should be done in a better way, since functions can be anywhere from 1 to 5000 instructions. (maybe based on host timer, or an interrupt flag from a scheduler thread)
* Address feedback minus CompareAndSwap change.
* Use default ReservedRegion granularity.
* Merge CompareAndSwap with its V128 variant.
* We already got the source, no need to do it again.
* Make sure all background translation threads exit.
* Fix CompareAndSwap128
Detection criteria was a bit scuffed.
* Address Comments.
* Implement TEQ and MOV (Imm16)
* Initial work on A32 instructions + SVC. No tests yet, hangs in rtld.
* Implement CLZ, fix BFI and BFC
Now stops on SIMD initialization.
* Exclusive access instructions, fix to mul, system instructions.
Now gets to a break after SignalProcessWideKey64.
* Better impl of UBFX, add UDIV and SDIV
Now boots way further - now stuck on VMOV instruction.
* Many more instructions, start on SIMD and testing framework.
* Fix build issues
* svc: Rework 32 bit codepath
Fixing once and for all argument ordering issues.
* Fix 32 bits stacktrace
* hle debug: Add 32 bits dynamic section parsing
* Fix highCq mode, add many tests, fix some instruction bugs
Still suffers from critical malloc failure 😩
* Fix incorrect opcode decoders and a few more instructions.
* Add a few instructions and fix others. re-disable highCq for now.
Disabled the svc memory clear since i'm not sure about it.
* Fix build
* Fix typo in ordered/exclusive stores.
* Implement some more instructions, fix others.
Uxtab16/Sxtab16 are untested.
* Begin impl of pairwise, some other instructions.
* Add a few more instructions, a quick hack to fix svcs for now.
* Add tests and fix issues with VTRN, VZIP, VUZP
* Add a few more instructions, fix Vmul_1 encoding.
* Fix way too many instruction bugs, add tests for some of the more important ones.
* Fix HighCq, enable FastFP paths for some floating point instructions
(not entirely sure why these were disabled, so important to note this
commit exists)
Branching has been removed in A32 shifts until I figure out if it's
worth it
* Cleanup Part 1
There should be no functional change between these next few commits.
Should is the key word. (except for removing break handler)
* Implement 32 bits syscalls
Co-authored-by: riperiperi <rhy3756547@hotmail.com>
Implement all 32 bits counterparts of the 64 bits syscalls we currently
have.
* Refactor part 2: Move index/subindex logic to Operand
May have inadvertently fixed one (1) bug
* Add FlushProcessDataCache32
* Address jd's comments
* Remove 16 bit encodings from OpCodeTable
Still need to catch some edge cases (operands that use the "F" flag) and
make Q encodings with non-even indexes undefined.
* Correct Fpscr handling for FP vector slow paths
WIP
* Add StandardFPSCRValue behaviour for all Arithmetic instructions
* Add StandardFPSCRValue behaviour to compare instructions.
* Force passing of fpcr to FPProcessException and FPUnpack.
Reduces potential for code error significantly
* OpCode cleanup
* Remove urgency from DMB comment in MRRC
DMB is currently a no-op via the instruction, so it should likely still
be a no-op here.
* Test Cleanup
* Fix FPDefaultNaN on Ryzen CPUs
* Improve some tests, fix some shift instructions, add slow path for Vadd
* Fix Typo
* More test cleanup
* Flip order of Fx and index, to indicate that the operand's is the "base"
* Remove Simd32 register type, use Int32 and Int64 for scalars like A64 does.
* Reintroduce alignment to DecoderHelper (removed by accident)
* One more realign as reading diffs is hard
* Use I32 registers in A32 (part 2)
Swap default integer register type based on current execution mode.
* FPSCR flags as Registers (part 1)
Still need to change NativeContext and ExecutionContext to allow
getting/setting with the flag values.
* Use I32 registers in A32 (part 1)
* FPSCR flags as registers (part 2)
Only CMP flags are on the registers right now. It could be useful to use
more of the space in non-fast-float when implementing A32 flags
accurately in the fast path.
* Address Feedback
* Correct FP->Int behaviour (should saturate)
* Make branches made by writing to PC eligible for Rejit
Greatly improves performance in most games.
* Remove unused branching for Vtbl
* RejitRequest as a class rather than a tuple
Makes a lot more sense than storing tuples on a dictionary.
* Add VMOVN, VSHR (imm), VSHRN (imm) and related tests
* Re-order InstEmitSystem32
Alphabetical sorting.
* Address Feedback
Feedback from Ac_K, remove and sort usings.
* Address Feedback 2
* Address Feedback from LDj3SNuD
Opcode table reordered to have alphabetical sorting within groups,
Vmaxnm and Vminnm have split names to be less ambiguous, SoftFloat nits,
Test nits and Test simplification with ValueSource.
* Add Debug Asserts to A32 helpers
Mainly to prevent the shift ones from being used on I64 operands, as
they expect I32 input for most operations (eg. carry flag setting), and
expect I32 input for shift and boolean amounts. Most other helper
functions don't take Operands, throw on out of range values, and take
specific types of OpCode, so didn't need any asserts.
* Use ConstF rather than creating an operand.
(useful for pooling in future)
* Move exclusive load to helper, reference call flag rather than literal 1.
* Address LDj feedback (minus table flatten)
one final look before it's all gone. the world is so beautiful.
* Flatten OpCodeTable
oh no
* Address more table ordering
* Call Flag as int on A32
