re PR middle-end/78566 (gcc.dg/uninit-pred-6_[abc]*.c regressions on some non-x86 platforms)
PR middle-end/78566
* tree-ssa-uninit.c (can_one_predicate_be_invalidated_p): Change
argument type to a pred_chain.
(can_chain_union_be_invalidated_p): Use pred_chain instead of a
worklist.
(flatten_out_predicate_chains): Remove.
(uninit_uses_cannot_happen): Rename from
uninit_ops_invalidate_phi_use.
Change logic so that we are checking that the PHI use will
invalidate _ALL_ possibly uninitialized operands.
(is_use_properly_guarded): Rename call to
uninit_ops_invalidate_phi_use into uninit_uses_cannot_happen.
