Paulo Matos c480b0ba41 asm_tests: Fix quiet and signalling nan propagation 2025-09-23 13:48:45 +02:00
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 b3d88c043d Merge pull request #4894 from pmatos/feature/improve-TestFiltering 
Support configuration-specific known failures in asm_tests
 2025-09-19 11:52:21 -07:00
Paulo Matos edd36dac91 Support configuration-specific known failures in asm_tests 
This allows Known_Failures files to contain either:
- Partial paths (existing): Test_X87_F64/SomeTest.asm (affects all configs)
- Full paths (new): jit_1/Test_64Bit_X87_F64/SomeTest.asm (specific config)

For example: Mark only the jit_1 (-n 1) configuration as failing:
jit_1/Test_64Bit_X87_F64/Memcopy_int_F64.asm

FEX: Fixes SIGILL reporting
 2025-09-18 23:35:25 +02:00
Ryan Houdek 3b2ebafd83 unittests/FEXLinuxTests: Adds simple sigill test 
Just checks that RIP, siginfo rip, REG_ERR and REG_TRAPNO are correct.
 2025-09-18 11:26:15 -07:00
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 4f0d35bae0 unittests/FEXLinuxTests: Adds test for x87 save/restore testing 2025-09-15 13:20:58 -07:00
Ryan Houdek de6d907e27 SignalDelegator: Correctly save and restore x87 state. 
We need to read the current x87 TOP location and rotate the values when
saving and restoring the context state on Linux. Wasn't visible in the
ASM tests since we read the FEX's CPU state directly there.

FEX: Rebrand FEXInterpreter as FEX
 2025-09-15 13:19:58 -07:00
Ryan Houdek 85e67f92c5 FEX: Rebrand FEXInterpreter as FEX 
Still creates a copy of FEXInterpreter from FEX for downstream projects
to have some time to get off the old name. Creating a symlink is kind of
a pain in cmake so just doing an install copy is easy.

Lioncache 056abb5901 IR: Add missing includes

Lioncache af28406dbc IR: Remove unnecessary friend class declarations from OrderedNode 
These classes don't exist anymore, so we can get rid of these declarations.

FEXLinuxTests: Adds a small sleep for consistency
 2025-09-13 13:24:39 -07:00
Ryan Houdek 736a73453f FEXLinuxTests: Adds a small sleep for consistency 
Sleep a second to make this test more consistent. Sometimes the
filesystem times are slightly different than wallclock times.

Ryan Houdek 6ced309c5c IoctlEmulation: Finish v4l2 implementation 2025-09-12 19:59:56 -07:00
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.
 2025-09-12 16:07:01 -07:00
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.

Ryan Houdek 315ee90837 unittests/ASM: Enables some previously disabled tests 
The new Zen system in CI has a new enough kernel for these tests.

Just need to modify the tests to be safe for our signal handler.

Ryan Houdek 278574ce91 unittests/ASM: Fixes xlat test so it can be run 
Just need to make sure to save and restore gs/fs in the test, otherwise
our signal handler gets /very/ upset.
