`-E`

This option instructs the compiler to execute only the preprocessor step.

By default, output from the preprocessor is sent to the standard output stream and can be redirected to a file using standard UNIX and MS-DOS notation.

You can also use the -o option to specify a file for the preprocessed output. By default, comments are stripped from the output. The preprocessor accepts source files with any extension, for example, .o, .s, and .txt.

To generate interleaved macro definitions and preprocessor output, use -E --list_macros.

Example

armcc -E source.c > raw.c
