P

Tells the compiler to stop the compilation process and write the results to a file.

Syntax

Linux:
-P
macOS:
-P
Windows:
/P
Arguments
None
Default
OFF
Normal compilation is performed.
Description
This option tells the compiler to stop the compilation process after C or C++ source files have been preprocessed and write the results to files named according to the compiler's default file-naming conventions.
On Linux systems, this option causes the preprocessor to expand your source module and direct the output to a
.i
file instead of
stdout
. Unlike the
-E
option, the output from
-P
on Linux does not include #line number directives. By default, the preprocessor creates the name of the output file using the prefix of the source file name with a
.i
extension. You can change this by using the
-o
option.
Alternate Options
Linux
and
macOS*
:
-F
Windows: None

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
