Compiler Error C2218

'__vectorcall' cannot be used with '/arch:IA32'

Remarks

The __vectorcall calling convention is only supported in native code on x86 and x64 processors that include Streaming SIMD Extensions 2 (SSE2) and above. For more information, see __vectorcall.

To fix this error, change the compiler options to target SSE2, AVX or AVX2 instruction sets. For more information, see /arch (x86).
