First (and most importand) step to achieve support of bare-metal 
platforms is druntime implementation.

Before, I successfully implemented druntime hacks for checking 
possibility of work D (not betterC!) on STM32 platform ("Hello, 
world!" and druntime unittests are passed):

Unfortunately, without changes to the existing druntime code 
organization it seems to impossible to support different 
non-mainstream architectures. And, at first, this applies to 
embedded ones.

Therefore, please support (or give constructive criticism 
feedback) this initiative:
