Compiler Command-line Options
It is possible to repeatedly specify this option on the command line. This results in
preincluding the files in the order specified.
Example
armcc --preinclude file1.h --preinclude file2.h -c source.c

2.1.133 --preprocessed
This option forces the preprocessor to handle files with .i filename extensions as if
macros have already been substituted.
Usage
This option gives you the opportunity to use a different preprocessor. Generate your
preprocessed code and then give the preprocessed code to the compiler in the form of a
filename.i file, using --preprocessed to inform the compiler that the file has already
been preprocessed.
Restrictions
This option only applies to macros. Trigraphs, line concatenation, comments and all
other preprocessor items are preprocessed by the preprocessor in the normal way.
If you use --compile_all_input, the .i file is treated as a .c file. The preprocessor
behaves as if no prior preprocessing has occurred.
Example
armcc --preprocessed foo.i -c -o foo.o
