Cygwin too, of course, and I think Darwin may have some quirks in that area
as well.
I want to get data dependence information about an basic block, which
contains RTLs.
What functions or data structure should I use ?

Data dependence analysis is done in sched-deps.c. You can have a look
at build_intra_loop_deps function in ddg.c (which constructs data
dependency graph for modulo scheduler) to see how it is used.

Hello
To me it looks like, that support for Thread Local Storage exists on ARM
cpu's.
When needed the compiler is going to fetch the base pointer by a
internal __builtin_thread_pointer() call.
This is either a call to __aeabi_read_tp() or a Coprocessor fetch
instruction.
