Description
This option tells the compiler to use the vector calling convention (__vectorcall) when passing vector type arguments.
It causes each function in the module to compile as __vectorcall unless the function is declared with a conflicting attribute, or the name of the function is main.
This option has been added for Microsoft compatibility.
For more details about the __vectorcall calling convention, see the Microsoft documentation.
