SIMD?

Out of sheer curiosity, is there SIMD on the PSP? (for example, using gcc intrinsics)

Do I need to set any compiler flags to take advantage of them?

Thanks

VFPU is a 32-bit float-point coprocessor using SIMD. But psp-gcc doesn't know about it and so doesn't have intrinsics for VFPU, only psp-as. Allegrex and standard FPU have no SIMD operation.

Ah, I see. Thanks

I guess that means no SIMD for me if I don't want to go into ASM.

Where can I find the complete list of VFPU instructions?
