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.
This option only applies to host compilation. When
offloading is enabled, it does not impact device-specific compilation.
