Ryan Houdek e5680e031d Merge pull request #4835 from pmatos/fix/classify 
Fix quiet and signalling nan propagation
 2025-09-23 11:17:37 -07:00
Paulo Matos e7a47a647c Fix quiet and signalling nan propagation 
This adds a new mode X87StrictReducedPrecision.
The strict reduced precision is like the reduced precision but adds extra checks,
like the currently implemented nan and snan propagations.

Fix for __builtin_issignaling() test of SPEC2017 classify test.

Ryan Houdek efe401c7a4 OpcodeDispatcher: Fixes fxsave x87 register storing 
These get stored based on the current rotation of TOP. So we need to be
a bit careful with how we do this storing. A smidge of overhead, but
nothing unexpected.

Ryan Houdek dd4f508b77 FEX: Fixes SIGILL reporting 
Two bug fixes here.
- We weren't reporting a correctl ErrorRegister. Needs to contain
  PF_INSTR at least.
- We weren't setting siginfo->si_addr in the case of `FaultToTopAndGeneratedException`

Fixes Mafia 2 (Classic)

Ryan Houdek a30593efd6 OpcodeDispatcher: Removes a log about unknown segments 
This behaves like `UnimplementedOp`, giving a SIGILL if it actually gets
hit.

Ryan Houdek 3fa400bc55 Frontend: Improve DecodeInst size from 128 bytes to 80 
We were paying a large cost per Literal type that we can special case
for the two class of instructions that use a 64-bit literal.

If we packed this would get to a further 62 bytes but probably not worth
it.

Ryan Houdek 90ea16325a Frontend: Move a couple of members from DecodeInst 
LastEscapePrefix doesn't need to be in DecodeInst, and we can have a
couple of flags for ForceTSO/DecodedSIB/DecodedModRM.

LC 30dd9ed267 Merge pull request #4863 from Sonicadvance1/more_cpuid 
CPUID: Adds new CPU product names that exist
 2025-09-10 23:09:33 -04:00
Ryan Houdek 58b5620f97 FEXCore: Fixes OOB access on x87 reduced precision loads 
x87 80-bit loads, both BCD and regular tword were loading 128-bits of
data when reduced precision was enabled. This was an oversight from the
previous fix a while ago.

Adds a specific reduced precision test for this, and updates the current
test to ensure stores are still tested as well.

Billy Laws 93096c27f9 Dispatcher: Fix FABI_F32_I16_F80_PTR argument size 
This takes an f80 as input and returns an f32. A copy-paste error had
this truncating the input float if !TMP_ABIARGS.

Billy Laws d2714f3338 JIT: Check for suspend interrupts at back-edges

never getting checked.

Billy Laws a2286cb00a OpDispatcher: Only use the MM register cache when in MMX state 
Since the X87 pass now performs its own MM register caching, these must
be mutually exclusive.
 2025-09-09 21:30:33 +01:00
Billy Laws 481787d45c OpDispatcher: Avoid using the register cache for AbridgedFTW 
This is now cached internally in the X87 pass, and all operations
outside of that that use it are rare so can afford loading/storing
directly from context after flushing x87 regs.
 2025-09-09 21:30:30 +01:00
Billy Laws d8c615ec65 OpcodeDispatcher: Only flush MMX registers on MMX -> x87 transitions 
Flushing other regs is not necessary, and breaks any ConvertNZCVToX87 use
which relies previously saved NZCV values as the flag-setting NZCV op after
the save could trigger a flush of NZCV.

Paulo Matos 14256e7a90 Fix mapping for VS and VC condition codes 
This doesn't seem to be generated in-code therefore it's not fixing any
existing bug, but fixes the mapping for future uses of the condition code.
