-/* Perform reachability analysis and reclaim all unreachable nodes.
-
- The algorithm is basically mark&sweep but with some extra refinements:
-
- - reachable extern inline functions needs special handling; the bodies needs
- to stay in memory until inlining in hope that they will be inlined.
- After inlining we release their bodies and turn them into unanalyzed
- nodes even when they are reachable.
-
- - virtual functions are kept in callgraph even if they seem unreachable in
- hope calls to them will be devirtualized.
-
- Again we remove them after inlining. In late optimization some
- devirtualization may happen, but it is not important since we won't inline
- the call. In theory early opts and IPA should work out all important cases.
-
- - virtual clones needs bodies of their origins for later materialization;
- this means that we want to keep the body even if the origin is unreachable
- otherwise. To avoid origin from sitting in the callgraph and being
- walked by IPA passes, we turn them into unanalyzed nodes with body
- defined.
-
- We maintain set of function declaration where body needs to stay in
- body_needed_for_clonning
-
- Inline clones represent special case: their declaration match the
- declaration of origin and cgraph_remove_node already knows how to
- reshape callgraph and preserve body when offline copy of function or
- inline clone is being removed.
-
- - C++ virtual tables keyed to other unit are represented as DECL_EXTERNAL
- variables with DECL_INITIAL set. We finalize these and keep reachable
- ones around for constant folding purposes. After inlining we however
- stop walking their references to let everything static referenced by them
- to be removed when it is otherwise unreachable.
-
- We maintain queue of both reachable symbols (i.e. defined symbols that needs
- to stay) and symbols that are in boundary (i.e. external symbols referenced
- by reachable symbols or origins of clones). The queue is represented
- as linked list by AUX pointer terminated by 1.
-
- At the end we keep all reachable symbols. For symbols in boundary we always
- turn definition into a declaration, but we may keep function body around
- based on body_needed_for_clonning
-
- All symbols that enter the queue have AUX pointer non-zero and are in the
- boundary. Pointer set REACHABLE is used to track reachable symbols.
-
- Every symbol can be visited twice - once as part of boundary and once
- as real reachable symbol. enqueue_node needs to decide whether the
- node needs to be re-queued for second processing. For this purpose
- we set AUX pointer of processed symbols in the boundary to constant 2. */
