-MD, -MMD

Compiles or assembles source files and produces a list of makefile dependency rules suitable for use by a make utility.

armclang creates a makefile dependency file for each source file, using a .d suffix. Unlike -M and -MM, that cause compilation or assembly to stop after the preprocessing stage, -MD and -MMD allow for compilation or assembly to continue.

-MD lists both system header files and user header files.

-MMD lists only user header files.

Example

The following example creates makefile dependency lists test1.d and test2.d and compiles the source files to an image with the default name, a.out:

armclang --target=arm-arm-none-eabi -march=armv8-a -MD test1.c test2.c
