A few years ago I created a bare metal demo on an ARM Cortex-M4

that one could do bare metal programming for microcontrollers 
in D without any dependencies on C or assembly.  It was also a 
proof of some ideas I had about leveraging compile-time 
features of D to generate highly-optimized code (both small and 
fast) for these resource constrained systems.  I hit a wall, 
however, with Issue 14758[0], and ultimately abandoned D for 
other alternatives.


Well, that issue was recently fixed in GDC [1].  In addition, 
he GDC developers did some work to reduce the number of phony 
stubs one had to add to the runtime to get a build [2], removed 
the "shared is volatile" hack, and implemented the 
`volatileLoad/Store` intrinsics so I no longer need to do 
volatile access in assembly.  So, I decided to give it another 
try, and updated that demo. You can see the results at

Congratulations, Mike.

Could someone post to Hacker News?  I don't have enough rep for 
it to propagate.

Happy hacking!

Maybe good subject for an AMA (though not many upvoted so far). 
It's pretty cool that it was added on an afternoon during the 
hackathon.

Can always post another story later on explaining the practical 
benefits of static foreach (good topic for a D blog post) - 
marketing is about repetition.
