2.4 Using the C preprocessor
You can include the C preprocessor command #include in your assembly language
source file. If you do this, you must preprocess the file using the C preprocessor, before
using
armasm to assemble it. See ADS Compilers and Libraries Guide.
armasm correctly interprets #line commands in the resulting file. It can generate error
messages and debug_line tables using the information in the #line commands.
Example 2-4 shows the commands you write to preprocess and assemble a file,
sourcefile.s . In this example, the preprocessor outputs a file called preprocessed.s , and
armasm assembles preprocessed.s .
Example 2-4 Preprocessing an assembly language source file
armcpp -E < sourcefile.s > preprocessedfile.s
armasm preprocessedfile.s
