LC 56dd470528 x87StackOptimizationPass: Remove unnecesary return in Run() 
It's a void function, so we don't need this at the end
 2026-07-23 02:21:26 -04:00
LC 6741f53d87 x87StackOptimizationPass: Mark getValidMask()/getInvalidMask() as const 
These don't modify instance state.
 2026-07-23 02:18:33 -04:00
LC 19550c5417 x87StackOptimizationPass: Pass by const reference in setTop() 
Avoids redundant copies. Just a minor codegen saving.

FEXCore: Split out CodeBuffer management to its own file

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: Rename temporary CPU buffer allocator
 2026-07-20 20:50:56 -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 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.

LC 331655182d ThreadManager: Fix error return values in FrontendAllocateSlots() 
If ftruncate or the mmap ever fail for whatever reason, then we need to
return the current size, rather than the new size.

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.

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

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.
