LC 10a0fe2e71 SharedCodeBufferManager: Make AllocateNew() signature consistent with declaration 2026-07-23 01:42:41 -04:00
LC c9add0d292 SharedCodeBufferManager: Hoist prctl define into util header 
Same behavior, but just moves the potential define to be alongside all
of the others in the wrapper header.
 2026-07-23 01:40:49 -04:00
LC c239d09ea0 SharedCodeBufferManager: Add missing header 
Ensures the page size define is always visible.

Ryan Houdek d2c92808f5 FEXCore: Split out CodeBuffer management to its own file 
NFC

- Renames CodeBufferManager to SharedCodeBufferManager to be more
  explicit about it being shared between threads
- Renames `CodeBuffers` to `SharedCodeBuffers` to make it more explicit
  about sharing these buffers between threads.
- Separates the Manager to its own file so it is distinct from the rest
  of the CPUBackend code

Makes it easier to parse ownership and lifetime semantics of these
buffers.

JIT: Remove JIT detection string
 2026-07-20 21:07:23 -04:00
Ryan Houdek fe1ac1bc1d JIT: Remove JIT detection string 
Now that we have VMA region naming enabled on JIT buffers, this is no
longer used. Confirming a region is a JIT buffer is now just a case of
comparing the name that shows up in `/procfs/maps` rather than dumping
the first bytes of an unknown region.

Ryan Houdek 9edd27b214 JIT: Rename temporary CPU buffer allocator 
`TempAllocator` was a bit too opaque as to what the allocator was for,
so I kept needing to lookup its usage every couple of months. Rename it
to `TempCodeBufferAllocator` so I can remember that it is a temporary
allocator for the staging JIT code buffer more easily.

PassManager: Simplify initialization interface
 2026-07-19 16:28:07 -07:00
LC 53befc68c9 PassManager: Ensure GetPass() only queries the underlying pass mappings 
Previously this would create an entry in the map if it didn't exist.

LC 19f95d89ec PassManager: Add basic documentation 2026-07-21 12:10:26 -04:00
LC ecb9b3b7f8 PassManager: Constrain GetPass() template to Pass-derived objects 
Makes the particular conversion types constrained to catch any trivial
misuses.
 2026-07-21 12:10:26 -04:00
LC d619e36523 PassManager: Pass string by const reference where applicable 
Gets rid of potential extraneous copies. We also add handling for cases
where two passes with the same name are unintentionally added.
Previously we'd blindly overwrite the mapping.
 2026-07-21 12:09:16 -04:00
LC fa80d11960 PassManager: Remove SyscallHandler member 
This isn't used anymore, so we can get rid of it to further simplify
initialization.
 2026-07-21 11:28:12 -04:00
LC 2893d2b64f PassManager: Simplify pass initialization 
We don't conditionally add any passes, so we can simplify the interface
so that we just add all existing passes at once. Makes the core
initialization process a little more straightforward.
 2026-07-21 11:28:09 -04:00
LC 22bd10f3b1 CPUBackend: Remove unnecessary reinterpret_casts 
This both take a void*, so the casting is unnecessary to begin with,
since this would occur anyway without it. We can also avoid a
duplication to reduce line noise.

Core: Remove unnecessary bounds check in GenerateIR()
 2026-07-18 21:35:34 -07:00
LC ff213bbc5e Core: Move vars closer to usage scope in GenerateIR() 
Makes it so their purpose is more easily seen
 2026-07-21 04:44:47 -04:00
LC 56a4ca6e6a Core: Remove unnecessary bounds check in GenerateIR() 
We already check the bounds in the loop prior to calling at().
 2026-07-21 04:40:22 -04:00
LC 04d06d386f IRDumper: stringstream -> ostringstream 
These are purely output operations, so we don't need to use the more
heavyweight class.

Ryan Houdek c4a5ac892f AVX128: Optimize 256-bit vmovmaskpd as well 
Similar to #5757, but once the elements have been zipped together, we
can treat it identically to the 128-bit 32-bit element path.

Closes #3782

IREmitter: Mark some helpers as const
 2026-07-17 07:59:47 -07:00
Tony Wasserka c0c95da796 Arm64Emitter: Fix incorrect condition for constant NOP padding 
This needs to be enabled when *generating* caches, not at runtime when we're
loading them (unless we're compiling for validation).

Previous code would incorrectly disable NOP padding in FEXOfflineCompiler and
instead enable it at runtime when it wasn't needed.
 2026-07-17 12:47:51 +02:00
LC 8b612a87c6 IREmitter: Mark some helpers as const 
These don't modify internal state.
 2026-07-17 03:20:36 -04:00
LC c5eddd922d FEXCore: Resolve missing prototype warnings 
Makes sure we mark everything internally linked as necessary, or make
declarations visible to their implementation.

Tony Wasserka 228c351396 CodeCache: Use maximal code buffer size when generating code caches, too 
This is less likely to happen, but will still be required for very large libraries.

LC 4bb675a530 x87StackOptimizationPass: Reduce noise in slow push/pop paths 
Deduplicates the repeated rotate behavior.

LC 8d62773570 x87StackOptimizationPass: Make helpers internally linked 
Makes it obvious they're only used in this TU and allows the compiler to
warn if they ever become unused.
 2026-07-16 09:56:14 -04:00
LC 9e26c57643 x87StackOptimizationPass: Fix isValid() 
Previously this wouldn't have worked, since .first isn't a valid member.
The only reason it wasn't caught is because the function is never
instantiated.
 2026-07-16 09:56:14 -04:00
LC 35bc502062 x87StackOptimizationPass: Make use of std::array for FixedSizeStack 
Reduces the overall generated code for state management.

Drops the overall text size from 11447294 to 11441918

LC 4b4aa1cdbe Arm64Emitter: Pull FillSpecialRegs bools into a struct 
Makes this easily expandable over time without modifying the prototype,
and lets us be a little more informative at call sites.

LC 1325fef703 RFCE: Prefer accessing ops with C instead of CW 
CW is only intended when the op needs to be writable, but most of these
are only reading data.

LC d2d0ef1803 RFCE: Remove unnecessary std::invoke() 
We can just call this normally (and also make the constituent helper
function internally linked).

LC d6fb60d512 RegisterAllocationPass: Ensure pair reg invariant 
Allows us to actually catch if this requirement ever gets broken in
the future.

LC ef35474f88 VectorOps: Simplify 256-bit VAddV

 2026-07-15 04:43:47 -04:00
LC f2212a497b x87StackOptimizationPass: Remove shadowing variable in PUSHSTACK case 
No behavioral change, since the one in the outer scope does the same thing.
 2026-07-14 08:01:30 -04:00
LC 9e8e87bbb2 AtomicOps: Avoid constrained unpredictable case in TelemetrySetValue() 
STLXR cannot use the same register as both the status register and the
value register, otherwise it's architecturally unpredictable
behavior.

Only applies to hardware without FEAT_LSE, so this only meaningfully
affects hardware using the v8.0 spec, since FEAT_LSE becomes mandatory
in v8.1 and newer.

LC 4254c0f5a9 RegisterAllocationPass: Function cleanup
