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 SYCL

) 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.

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.
