Do you mean ltsmaster or master? There shouldn't be much change 
with the former.

The TLS patches shouldn't be needed after llvm 3.8 or so, ie you 
should be able to use a stock llvm for iOS:

That makes no sense: there are no C++ files in the runtime, only 
C and D. Anyway, if you only care about betterC, you don't want 
to build the runtime, so doesn't matter.

My suggestion is that you simply build his working ldc for iOS 
project, but with the betterC patch I linked you backported. Once 
you're sure that's working, you can try these more advanced 
steps. Have you tried that? It's not clear.
