Compilation Phases

The Intel® oneAPI DPC++/C++ Compiler processes C/C++ and DPC++ language source files. Compilation can be divided into these major phases:

• Preprocessing

• Semantic parsing

• Optimization

• Code generation

• Linking

The first four phases are performed by the compiler:

//# Linux*

//# C++
icx or icpx
//#DPC++ 
dpcpp

//# Windows*

//# C++
icx or icpx
//#DPC++ 
dpcpp-cl

If you specify the c option at compilation time, the compiler will generate only object files. You will need to explicitly invoke linker in order to generate the executable.

This content is specific to C++; it does not apply to DPC++. If you are compiling for a 32-bit target, you may either set the environment variable, INTEL_TARGET_ARCH_IA32, or use the [Q]m32 option. If you used the c option you will need to pass the [Q]m32 option to the linker as well.

If you specify the E and P options when calling the compiler, the compiler will only generate the preprocessed file with an .i extension.
