Math Kernel Library Developer Guide
The IA-32 architecture implementation of Intel® oneAPI Math Kernel Library supports the Compaq Visual Fortran* (CVF) calling convention by providing the stdcall interface.
Although the Intel® oneAPI Math Kernel Library does not provide the CVF interface in its Intel® 64 architecture implementation, you can use the Intel® Visual Fortran Compiler to compile your Intel® 64 architecture application that calls Intel® oneAPI Math Kernel Library and uses the CVF calling convention. To do this:
Provide the following compiler options to enable compatibility with the CVF calling convention:
/Gm or
/iface:cvf
Additionally provide the following options to enable calling Intel® oneAPI Math Kernel Library from your application:
/iface:nomixed_str_len_arg
