In 16.0, the Intel C++ Compiler provided two compilers (one based on EDG, another based on Clang).
From the 16.0 documentation:
Using the Command Line
To invoke the compiler from the command line, use a command similar to the following:
For C source files: icc my_source_file.c or icl my_source_file.c
For C++ source files: icpc my_source_file.cpp or icl++ my_source_file.cpp
Following successful compilation, the compiler creates an executable file in the current directory.
icl/icl++ is a Clang-based front-end. You can use Clang options with this compiler. icc/icpcis an EDG-based front-end. You cannot use Clang options with icc/icpc.
But I'm not seeing a similar description now in 19.0 document.
