[LLVMdev] Use rand_r() instead of non-reentrant thread-unsafe rand() in GetRandomNumber()
I don't know if __thread is well-supported enough on compilers to use in
LLVM core code. LLVM has its own support class: ThreadLocal
http://llvm.org/doxygen/classllvm_1_1sys_1_1ThreadLocal.html
And if randr_r() is obsolete, I'm not sure we should be using it. What
platforms have you tested this on? Is it available on Windows, Mac, BSDs?
If not touching global state is important enough, perhaps we should add a
(simple) random number generator to the Support library. I don...

Agreed, done.
One thing I'm not sure about is this statement in docs:
POSIX.1-2008 marks *rand_r*() as obsolete.
- And... what is the replacement?
