[gomp4] expand acc_on_device earlier

I've committed this to gomp4 branch. It expands the acc_on_device builtin earlier in the new oacc_xform pass. This will allow more optimization earlier on. The existing expansion point now only needs to deal with the host-side case. nathan 2015-08-02 Nathan Sidwell gcc/ * omp-low.c (oac

[PATCH] Avoid recomputing multiple times the defining predicate-chain for the same PHI

In the uninit pass, the function is_use_properly_guarded is called consecutively by find_uninit_use, each time being passed the same PHI parameter, and each time we needlessly compute, simplify and normalize the same defining predicate-chain of that PHI. This patch fixes this inefficiency by tweak
