A few years ago I created a bare metal demo on an ARM Cortex-M4
microcontroller entirely in D. It was just a demonstration
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.
