Lioncache 4e83ca67f5 CPUBackend: std::move shared_ptr where applicable 
Very minor, just avoids churning reference count increments and decrements.

Billy Laws 06466bac0e Dispatcher: Drop the L1 lookup 
This is almost never hit outside of exceptional cases like signals/SMC,
for which other overheads dominate.
 2025-09-03 18:26:47 +01:00
Billy Laws 156edcacb2 Dispatcher: Move the EC entrypoint check prior to the L1 lookup 
Profiling shows this is by far the hottest path, as every DX call will
hit this (as arm64ec functions in a vtable). L2 hits are much rarer and
L1 almost never hits since that is looked up inline in most cases.

Gets rid of unnecessary dependencies and clarifies previously indirect dependencies.

Billy Laws 2c883d7cdc OpDispatcher: Force a recheck of TF after POPF 
The dispatcher/block linker will handle this, but if the instruction
following a POPF flag doesn't otherwise trigger one of those the
interrupt would be missed.

Lioncache 1edacf05e9 ConstProp: Remove file 
This was left in the tree, but the functionality was removed a while ago, so we can delete this.
 2025-09-02 14:50:22 -04:00
Lioncache 1f756fb386 General: Replace usages of .at(0) with .data() where applicable 
This is generally more straightforward in cases where bounds checking isn't necessary.
 2025-09-02 13:03:37 -04:00
Lioncache 5ebdc01783 F80Fallbacks: Remove unnecessary memset 
X80SoftFloat instances already initialize zeroed out in the default constructor.

Lioncache aa29201e00 Dispatcher: Reduce header dependencies 
Gets rid of some unnecessary dependencies and also resolves some indirect dependencies.

Ryan Houdek 4a71edf7bc Merge pull request #4811 from pmatos/fix/SPEC_GCC-C-execute-ieee-fp-cmp-8l 
Fix IEEE 754 unordered comparison detection in x87 floating-point operations
 2025-09-01 14:39:59 -07:00
Ryan Houdek fbf982f001 Merge pull request #4809 from lioncash/ir 
IR: Remove some unimplemented prototypes
 2025-09-01 14:39:39 -07:00
Paulo Matos 3d92c1fb32 Fix IEEE 754 unordered comparison detection in x87 floating-point operations 
Fix SoftFloat IsNan - custom detection matches IEEE754 semantics.
Sets Invalid Operation flags properly for NaN comparisons.

Fixes: GCC-C-execute-ieee-fp-cmp-8l test
__builtin_isunordered() now returns correct values for both NaN and normal operands

Lioncache 221ee1a122 IREmitter: Remove unimplemented prototypes 
Get/SetPackedRFLAG() functions were moved to the opcode dispatcher, but these were
accidentally left behind.
 2025-08-29 12:00:53 -04:00
Lioncache 2b29f90c92 IREmitter: Remove unused <array> header 
Just one less include to worry about
 2025-08-29 11:57:03 -04:00
Lioncache d7ec0e570f IR: Make IsFragmentExit() internally linked 
This isn't used outside of the IR emitter. Plus, IsBlockExit() is already a more general interface to use,
since it handles the fragment exit case as well.

Lioncache 86c2144943 Core: Simplify define in InitCore() 
Instead of inverting off a separate define, we can combine both checks together.
 2025-08-29 11:30:48 -04:00
Lioncache ee85230db2 Dispatcher: Remove unused IntCallbackReturnAddress member 
Turns out that this isn't used anymore. Found due to an unused field warning
when moving all public members into the private section.
 2025-08-29 11:19:10 -04:00
Lioncache fde99a8dc1 Dispatcher: Centralize SignalDelegator config creation 
Since all of the information comes from the Dispatcher, we can have the dispatcher
provide that information. This way we can also eliminate a bunch of now-redundant
public interface members and simplify the config setup within InitCoreImpl().

Conveniently, this also allows making all members of the dispatcher non-public.

Lioncache 2e692a1146 SignalDelegator: Move struct outside of SignalDelegator 
The name itself is already qualified with SignalDelegator, so this can reasonably be outside the class itself.
This also allows for forward declarations of the config struct

Ryan Houdek add54b8089 X86Tables: Convert AVX tables to constexpr 
One set of tables for 128-bit and one set of tables for 256-bit.
This one took a bit longer since I needed to convert a few handlers over
to `Bind`. With this all of our x86 tables are costexpr so they end up
in RO mapped memory which is great.

Ryan Houdek 87a19c7938 FEXCore: Move SecondaryGroupTables Arch specific ops to a table 
No runtime-installation necessary.

Ryan Houdek 0ab1241f09 X86Tables: Switch OpDispatch pointer over to a union 
A wild use case of union over a variant because we don't want to
increase the encoding size from 128-bit to 256-bit (because of padding).
The type of operation is encoded with the table operation type, so a
variant is unnecessary and we get to keep the 128-bit encoding.

This allows us to have "recursive" x86 table descriptions. But in
reality this is going to only be one layer deep. As this will allow the
Frontend decoder to select instruction encodings based on arch bitness
once the tables are generated correctly.
