Portability Options

This content is specific to C++; it does not apply to
DPC++
.
A challenge in porting applications from one compiler to another is making sure there is support for the compiler options you use to build your application. The
Intel® oneAPI
DPC++/C++
Compiler
supports many of the options that are valid on other compilers you may be using.
The following sections list compiler options that are supported by the
Intel® oneAPI
DPC++/C++
Compiler
and the following:
Options that are unique to either compiler are not listed in these sections.

Options Equivalent to Microsoft C++ Options (Windows*)

The following table lists compiler options that are supported by both the
Intel® oneAPI
DPC++/C++
Compiler
and the Microsoft C++ Compiler.
For complete details about these options, for example, the possible values for <n> when it appears below, see the Microsoft Visual Studio C++ documentation.
