At least DMD had some problems with bracketed sections with the 
linker. DMD doesn't use bracketed sections anymore. Why do you 
need bracketed sections? At least OS X has API's available to 
access a specific sections. I would assume iOS also has does 
API's.

Would it be possible to output OS X native TLS for iOS? Does LLVM 
allow that? If that's possible we could experiment with adding 
the TLS code from the dynamic linker to druntime and see what 
happens. Theoretically it should work. It don't think the dynamic 
linker does anything that a regular application can't do.
