Ryan Houdek 3160e0a430 FEXCore: Keep PCMPISTRI arguments in vectors longer
This reduces our codegen size and removes a few umov instructions.
Performance falls within noise but this small change will allow us to do
more vector optimizations in C code in the future.

Ryan Houdek 6abf5b90b7 FEXCore/JIT: Pass Softfloat arguments as vector registers
This is preparation work to allow passing the corestate to the x87 soft
float handlers directly for some profile stats.

Performance-wise, this change falls within noise because it basically
moves the GPR->Vector moves from the JIT in to C code, my microbench saw
the largest excursion of 5% but that's still within noise in the current
design of my bench.

A more tangible win from this change alone is less codegen on the JIT
side.

Ryan Houdek 00aa4ddea0 FEXCore/Softfloat: Support loading and storing SoftFloat to vector registers 2025-02-10 12:53:25 -08:00
Paulo Matos 10ec6b63b6 Fix FXTRACT for 0.0 and -0.0
Fixes fxtract by returning the correct values for 0.0 and -0.0. We moved the split of fxtract into _sig and _exp, to the opcode dispatcher, to ease some comparisons.

Also removed the IR node F80XTRACTStack which is not needed anymore.

Paulo Matos f35a212f06 Fix FScale'ing zero that should return zero
Added tests will fail without the current patch.
This will properly check if we return the correct sign of zero.

Billy Laws 696503680a F80: Drop dependency on state stored in TLS
Windows cannot support the implicit TLS as was used prior, so introduce
a state structure and pass it in to functions where necessary.

Ryan Houdek 8955f83ef6 Softfloat: Fixes Integer indefinite return for 16-bit signed values
Regardless of positive or negative value, if the converted integer
doesn't fit in to the converted int16_t then it returns INT16_MIN.

Alyssa Rosenzweig af21b8f3c7 Move External/FEXCore/ to FEXCore/
It is not an external component, and it makes paths needlessly long.
Ryan seemed amenable to this when we discussed on IRC earlier.
