This is for version 2021.6 of the compiler.
This document contains information about the Intel® C++ Compiler Classic (icc for Linux* and icl for Windows*) compiler and runtime environment. The Intel® C++ Compiler Classic can be found in the Intel® oneAPI HPC Toolkit, Intel® oneAPI IoT Toolkit, or as a standalone compiler. More information and specifications can be found on the Intel® oneAPI DPC++/C++ Compiler main page.
The following are some important sections of the compiler developer guide:
Compiler Setup |
Compiler Setup explains how to invoke the compiler on the command line or from within an IDE. |
OpenMP* Support |
The compiler supports many OpenMP* features, including most of OpenMP* Version TR4: Version 5.0. |
Compiler Options |
Compiler Options provides information about options you can use to affect optimization, code generation, and more. |
Intrinsics |
Intrinsics let you generate more readable code, simplify instruction scheduling, reduce debugging, access the instructions that cannot be generated using the standard constructs of the C and C++ languages, and more. |
Pragmas |
Pragmas provide the compiler with the instructions for specific tasks, such as splitting large loops into smaller ones, enabling or disabling optimization for code, or offloading computation to the target. |
