Compiling Jolt with SSE targetting WASM about joltphysics HOT 4 CLOSED

Hi, it works great so far, thank you.

from joltphysics.

Is it not possible to just define JPH_USE_SSE (and potentially JPH_USE_SSE4_1, JPH_USE_SSE4_2) in your project?

So far I didn't enable SSE for the WASM target because Safari only fairly recently got support for it.

A couple of issues with just defining JPH_USE_SSE:

C:\code\substrata\jolt\Jolt\Core\Core.h(60,1): warning C4005: 'JPH_USE_SSE': macro redefinition

and there is some other code in the JPH_USE_SSE branches that Emscripten doesn't support:

C:/code/substrata/jolt\Jolt/Core/FPControlWord.h:22:3: error: use of undeclared identifier '_mm_setcsr' 22 | _mm_setcsr((mPrevState & ~Mask) | Value); | ^

C:/code/substrata/jolt\Jolt/Core/FPFlushDenormals.h:15:33: error: no template named 'FPControlWord' 15 | class FPFlushDenormals : public FPControlWord<_MM_FLUSH_ZERO_ON, _MM_FLUSH_ZERO_MASK> { }; | ^

Can you try this latest fix that I submitted?
