2.1.60 -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.
Example
armcc -E source.c > raw.c

output.
