LC 585286a617 IRValidation: Remove unused members from BlockInfo 
HasExit is assigned to but never used, but we check this condition a
different way right after leaving the main loop anyway.
 2026-07-24 16:00:20 -04:00
LC 4904fd43e9 IRValidation: Make BlockInfo private 
This isn't used outside the context of the pass.
 2026-07-24 16:00:20 -04:00
LC 9e3f287c1f IRValidation: Use C instead of CW 
This op isn't mutated anywhere in the pass.
 2026-07-24 16:00:20 -04:00
LC f5e4e26e08 IRValidation: Move var closer to usage 
Same behavior, just more compact.
 2026-07-24 16:00:20 -04:00
LC 6c5a39e164 IRValidation: Turn ORs with true into assignment 
These are just unconditional setting to true anyway.
 2026-07-24 16:00:17 -04:00
LC 6d4c80adff x87StackOptimizationPass: Remove IR member 
This is only used in the store helpers, so we can just pass it in
directly
 2026-07-23 02:26:46 -04:00
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.
 2026-07-23 02:17:02 -04:00
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.
 2026-07-21 12:10:26 -04:00
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 04d06d386f IRDumper: stringstream -> ostringstream 
These are purely output operations, so we don't need to use the more
heavyweight class.
 2026-07-21 04:29:03 -04:00
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.
 2026-07-17 02:48:45 -04:00
LC 4bb675a530 x87StackOptimizationPass: Reduce noise in slow push/pop paths 
Deduplicates the repeated rotate behavior.
 2026-07-16 10:31:40 -04:00
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

Ryan Houdek 34ef28dea5 Merge pull request #5749 from lioncash/calc 
RedundantFlagCalculationElimination: Minor tidying
 2026-07-15 09:05:45 -07:00
Ryan Houdek 0f2463dda2 Merge pull request #5748 from lioncash/invariant 
RegisterAllocationPass: Ensure pair reg invariant
 2026-07-15 09:04:38 -07:00
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.
 2026-07-15 07:06:23 -04:00
LC d2d0ef1803 RFCE: Remove unnecessary std::invoke() 
We can just call this normally (and also make the constituent helper
function internally linked).
 2026-07-15 07:03:09 -04:00
LC d6fb60d512 RegisterAllocationPass: Ensure pair reg invariant 
Allows us to actually catch if this requirement ever gets broken in
the future.
 2026-07-15 06:46:24 -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 4254c0f5a9 RegisterAllocationPass: Function cleanup 
Marks a few functions const or static to clarify usage a little more.
 2026-07-13 15:26:51 -04:00
Ryan Houdek 356d461123 Merge pull request #5734 from lioncash/bytes 
Common/BitSet: Amend byte size retrieval
 2026-07-13 07:07:00 -07:00
LC c0b2eec5de IR: Enclose straggler Desc comments in brackets 
Ensures the comments get rendered properly in output. We can also
make sure that the IR generation script catches this in the future.
 2026-07-13 08:59:45 -04:00
LC 9b8ae25491 Common/BitSet: Amend byte size retrieval 
This needs to divide by 8 to get a proper byte size for all type sizes.
The only usage of this is currently a uint64_t, so it worked by
coincidence, since sizeof(uint64_t) == 8.
 2026-07-13 08:17:27 -04:00
LC 9d3c388664 Crypto: Make use of XAR in SHA1NEXTE when available 
Lets us shave an instruction off on hardware that supports XAR.

Closes #5730
 2026-07-12 16:02:12 -04:00
LC 995e2657bb RegisterAllocationPass: Amend type cast in DecodeSRANode() 
Uses the proper type for StoreRegister. Same behavior though, due to
layout.
 2026-07-11 16:39:35 -04:00
LC 0bfef9008b IR: Use begin block type in operator-- 
Same behavior, just more correct from a descriptive PoV
 2026-07-10 07:31:25 -04:00
LC caa030714b IR: Remove unused VUShraI 
Given that this is currently unused and that we don't have the signed
equivalent implemented, we can just remove this for now.
 2026-07-10 04:15:52 -04:00
LC 710b85be70 IR: Remove need to specify element size for vector bitwise ops 
Element size doesn't really mean anything here, considering all bits are
acted upon independently of segmentation.

Makes using these ops a little bit less noisy.
 2026-07-09 13:26:51 -04:00
LC 6bc67609a3 [SVE256] Handle 256-bit blend operations much more efficiently 
We can massage a given selector into a valid predicate register bitmask
and then simply perform a merging move, which eliminates most busywork
around optimizing 256-bit blends.

In the future, once we drop SVE2.1 support in, we can use PMOV to
eliminate the load from memory and related constant management.
 2026-07-08 17:35:12 -04:00
LC 201216ba54 HostFeatures: Put SVE support querying into single function 
Lets us avoid open-coding long checks for the existence of either
SVE-128 or SVE-256.
 2026-06-30 03:34:17 -04:00
LC ef19242be3 IR: Add constant for swapping midsections of 256-bit vectors around 
This'll let us eliminate some pretty gnarly inserts while
ZIP1Q/UZP1Q/etc are still unavailable.

Ryan Houdek 280568df2f Merge pull request #5581 from lioncash/fwd 
Passes: Trim unnecessary forward declarations
 2026-06-21 20:05:23 -07:00
LC a1f90dd8d3 Passes: Trim unnecessary forward declarations 
Less visual noise and lingering types left in the header.
 2026-06-20 13:59:18 -04:00
LC 2a67261eac IntrusiveIRList: Amend signature for PostRA() 
PostRA is a bool, not an unsigned value. We can also adjust SpillSlots()
to use uint32_t like its returned data member.

Ryan Houdek 4428aea5ee IR: Adds support for printing strings 
I utilize this functionality quite heavily when debugging and I need
bread crumbs spread around. Instead of reimplementing it a dozen times,
just have it upstreamed.
