...gning small-scale embedded systems and pre-allocation is very meaningful in this context. 2. Which are the new register allocation algorithms currently under design? Do they support preallocation of registers (it is different to "fixing" a register in GCC parlance)? 3. Does LLVM work on PDGs (Program Dependence Graphs) as well? If yes, does the register allocation take on PDGs? Kind regards Nikolaos Kavvadias

As an alternative to the (post)-dominance frontier method I used the algorithm described in [1], section 9.5 "Program Dependence Graph" where you can find a method to build the CDG using only the post-dominator tree.

Hi Guys, I saw in the API that DominanceFrontier has been deprecated. Is this for real? I have read the computational issues but shouldn't that be left to the users of llvm? My concern is I am writing a Control Dependence module that uses Dominance-Frontier information. Getting rid of Dominance Frontiers will put me in a tight spot.
