LDC for android is working with most of druntime & phobos.   you 
can install ldc 1.13.0 from termux,  I am also be able to build 
1.16 with some phobos & druntime small bugs.

IOS https://github.com/smolt/ldc-iphone-dev/releases only have 
0.17.0-alpha1 (2.068.2 FE) LLVM 3.6.2.

If LDC core team can only cherry-pick target/march  for IOS, then 
I think people will be easy to  try the ABI them self.
