The big question is how to best implement it, though.

 From an LDC perspective, the best would be to add support for emitting 
the TLS variables into a bracketed section and inserting runtime calls 
to access them directly to LLVM; then none of the LDC code (resp. the 
generated LLVM IR) would actually have to change.

That might be too much work for this option to be feasible, though – I 
never really looked at how the various targets lower TLS accesses 
(besides Win32/MinGW, where I contributed a few small fixes).

I suppose the best way to go about this would simply be to ask for 
advice on llvm-dev, probably somebody can judge the involved trade-offs 
much better than I can.
