Lol, what?
Don't misquote the wiki about LDC. If you can run DMD on your 
architecture, LDC has full support too.
The "lacking druntime/phobos support" is about architectures that 
are _not_ x86, x86_64, ARM, AArch64, PowerPC, MIPS, WebAssembly. 
DMD supports only a subset of what LDC (and GDC) support.
