Almost certainly no.

LDC has open AArch64 issues.
One is about quadruple-real support in Phobos 
(https://github.com/ldc-developers/ldc/issues/1516), with first 
(suspended) steps towards that goal pending upstream (as all 
non-DMD compilers need this at some point; 
https://github.com/dlang/phobos/pull/4036, 
https://github.com/dlang/phobos/pull/4047).
The other LDC issue concerns the ABI, especially varargs 
(https://github.com/ldc-developers/ldc/issues/1931).

None of the currently active LDC devs work with AArch64, so help 
would be greatly appreciated.
