Compiler Command-line Options
2.1.79 -M
This option instructs the compiler to produce a list of make file dependency lines
suitable for use by a make utility.
The compiler executes only the preprocessor step of the compilation. By default, output
is on the standard output stream.
If you specify multiple source files, a single dependency file is created.
If you specify the -o filename option, the dependency lines generated on standard
output make reference to filename.o, and not to source.o. However, no object file is
produced with the combination of -M -o filename.
Use the --md option to generate dependency lines and object files for each source file.
Example
You can redirect output to a file by using standard UNIX and MS-DOS notation, for
example:
armcc -M source.c > Makefile

2.1.80 --md
This option instructs the compiler to compile the source and write make file dependency
lines to a file.
The output file is suitable for use by a make utility.
The compiler names the file filename.d, where filename is the name of the source file.
If you specify multiple source files, a dependency file is created for each source file.
