Add multi-level function table (#2228)
* Add AddressTable<T>
* Use AddressTable<T> for dispatch
* Remove JumpTable & co.
* Add fallback for out of range addresses
* Add PPTC support
* Add documentation to `AddressTable<T>`
* Make AddressTable<T> configurable
* Fix table walk
* Fix IsMapped check
* Remove CountTableCapacity
* Add PPTC support for fast path
* Rename IsMapped to IsValid
* Remove stale comment
* Change format of address in exception message
* Add TranslatorStubs
* Split DispatchStub
Avoids recompilation of stubs during tests.
* Add hint for 64bit or 32bit
* Add documentation to `Symbol`
* Add documentation to `TranslatorStubs`
Make `TranslatorStubs` disposable as well.
* Add documentation to `SymbolType`
* Add `AddressTableEventSource` to monitor function table size
Add an EventSource which measures the amount of unmanaged bytes
allocated by AddressTable<T> instances.
dotnet-counters monitor -n Ryujinx --counters ARMeilleure
* Add `AllowLcqInFunctionTable` optimization toggle
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.
* Implement unmanaged dispatcher
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.
* Remove redundant null check
* Tune levels of FunctionTable
Uses 5 levels instead of 4 and change unit of AddressTableEventSource
from KB to MB.
* Use 64-bit function table
Improves codegen for direct branches:
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
* Fix PageTable symbol for host mapped
