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:
Example 
//# 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.
