Hi Joe, what is the target OS or libraries?  That makes a difference.

I personally haven't tested on a Cortex-M.  These are Thumb only and
later models are full Thumb-2.  I can say Thumb-2 suppport is good in
LDC and druntime/phobos; Thumb is not.  Support for embedded C libs like
newlib is probably lacking, but that is not Cortex-M specific.

Related - I'm working on a project based on newlib and FreeRTOS.  I may
do some of it in D for fun and to further newlib support in
druntime/phobos.
