Port from GCC* to the Intel® oneAPI DPC++/C++ Compiler

Advantages to Using the Intel® oneAPI DPC++/C++ Compiler

In many cases, porting applications from gcc to the Intel® oneAPI DPC++/C++ Compiler can be as easy as modifying your makefile to invoke the Intel® oneAPI DPC++/C++ Compiler (icx for C++ or dpcpp for DPC++) instead of gcc. Using the Intel® oneAPI DPC++/C++ Compiler typically improves the performance of your application, especially for those that run on Intel processors. In many cases, your application's performance may also show improvement when running on non-Intel processors. When you compile your application with the Intel® oneAPI DPC++/C++ Compiler, you have access to:

• Compiler options that optimize your code for the latest Intel® architecture processors.

• Advanced profiling tools (PGO) similar to the GNU profiler gprof.

• High-level optimizations (HLO).

• Interprocedural optimization (IPO).

• Intel intrinsic functions that the compiler uses to inline instructions, including various versions of Intel® Streaming SIMD Extensions and Intel® Advanced Vector Extensions.

• Highly-optimized Intel® oneAPI DPC++/C++ Compiler Math Library for improved accuracy.

Because the Intel® oneAPI DPC++/C++ Compiler is compatible and interoperable with gcc, porting your gcc application to the Intel® oneAPI DPC++/C++ Compiler includes the benefits of binary compatibility. As a result, you should not have to re-build libraries from your gcc applications. The Intel® oneAPI DPC++/C++ Compiler also supports many of the same compiler options, macros, and environment variables you already use in your gcc work.

Equivalent Macros

The Intel® oneAPI DPC++/C++ Compiler is compatible with the predefined GNU* macros.

See http://gcc.gnu.org for a list of compatible predefined macros.
