Lioncache 10c3b2fb5d SyscallHandler: Shrink definition struct from 24 to 16 bytes 
Just a minor space saving, given how many syscall definitions we'll
have.

Lioncache 74ae89865c SHMStats: Add missing virtual destructor 
This should be present for universally consistent behavior, regardless
of how the class is used.

Lioncache 7aa5bc0503 EnumUtils: Further simplify enum passthrough formatting 
Turns out a simpler way was added to the docs at some point and I never
noticed.

Lioncache d94b9fae94 SourceCodeResolver: Pass string_view by value for GenerateMap() 
Generally this should be passed as a value type unless there's a good
reason not to.

Addressing: Shave 8 bytes off AddressMode
 2025-10-06 14:01:09 -07:00
Lioncache c1cfd4db83 Addressing: Shave 8 bytes off AddressMode 
Just a trivial rearrangement, Drops the struct down to 40 bytes.
We can also make some functions take it by const reference so we
aren't churning some copies.

ThreadManager: Fix mmap usage to not take guest space
 2025-10-06 14:59:27 -04:00
Ryan Houdek 2cab87fbd0 ThreadManager: Fix mmap usage to not take guest space 
SHM stats and CallRet stack was accidentally using system mmap which
means it would take VA space from the guest. Ensure it uses the
Allocator helpers so that doesn't happen.

Gives 32-bit guests 8-ish megabyte of VA space back.

OpcodeDispatcher: Remove unimplemented function prototypes
 2025-10-06 10:18:18 -07:00
Lioncache 72cb29d36b OpcodeDispatcher: Remove unimplemented function prototypes 
Just cleans out the interface a little.

OpcodeDispatcher: Default alignment parameters for store helpers
 2025-10-06 09:11:49 -07:00
Lioncache a16d4ff1f3 OpcodeDispatcher: Deduplicate in LEAOp/SMSWOp 
We can shorten a few lines here by just storing the op addr value
to a local variable.
 2025-10-06 11:13:00 -04:00
Lioncache 305b1ecf2d OpcodeDispatcher: Default alignment parameters for store helpers 
Avoids actively doing this wonky thing where we're passing
iInvalid all over the place to mean variable alignment depending
on store element size or GPR size.

Makes using the API a little more visibly straightforward and makes
cases where alignment matters more explicit.

Lioncache 137aa59254 PrctlUtils: Move to include folder 
We can group more prctl value handling in here.

Allocator: Name FEX's VMA regions for allocation
 2025-10-05 22:40:58 -04:00
Ryan Houdek 45978474f3 Allocator: Name FEX's VMA regions for allocation 
Will allow external tools to track how much memory FEX allocates.
Necessary since we can't use traditional memory usage tools to track FEX
memory allocation independently of guest allocations. Plus most tools
like heaptrack hook allocation symbols, which break under jemalloc.

Using this information I can see with Steam loaded with my library that
FEX consumes ~825MB. Total process resident memory is 1204M, accounting
for around 379MB being used by steam itself. This is /relatively/ close
to my desktop running steam at around 261MB. There's a bit of variance
due to what Steam chooses to do at startup.

This tracking will be the first step towards seeing where our memory
usage is going.

 2025-10-05 11:53:56 -07:00
Lioncache 0b238d942e Common/StringConv: std::stoull -> std::strtoull for enum handler 
Missed this when simplifying the conversion facilities, but
we should be using std::strtoull here, as per the programming
concerns.
 2025-10-05 14:49:07 -04:00
Lioncache 16b09a9dd3 OpcodeDispatcher: Move off implicit _Select 
Resolves a lingering TODO.

These are no longer used.
 2025-10-05 13:26:51 -04:00
Lioncache c84801adb3 RedundantFlagCalc: Avoid vector copy in OptimizeParity() 
Previously this was making a copy of the vector, when we only
need to read from it.
 2025-10-05 12:17:45 -04:00
Lioncache 69f990c1f8 RedundantFlagCalc: Organize headers 
Also remove incorrect comment that this pass isn't used.

json_ir_generator: Minor cleanup
 2025-10-04 11:44:08 -07:00
Lioncache 3ff47cf677 json_ir_generator: Add missing error message 
ExitError() expects a string argument. Unlikely error case to be hit,
but we should still make the error useful to the reader.
 2025-10-04 11:00:05 -04:00
Lioncache 3165dce89e json_ir_generator: Turn IROpNameMap into a set 
This is only used to track for duplicates, so we only really need
the key name, since the values are never used.
 2025-10-04 11:00:00 -04:00
Lioncache d4fad0a3b0 json_ir_generator: Simplify some looping

Same behavior, but a little more straightforward
 2025-10-04 08:47:08 -04:00
Lioncache 6a1a505336 json_ir_generator: Add type annotations for top level vars 
Makes the types a little more explicit and also makes member
suggestions in IDEs (vscode, etc) work a little better.
