ENH: Created cmComputeLinkDepends to compute link dependencies.
- This will be useful for imported library dependencies
- Replaces old cmTarget analyze-lib-depends stuff for linking
- Formalizes graph construction and dump
- Explicitly represents dependency inferral sets
- Use BFS of initial dependencies to preserve order

Each link item is identified by +the string naming it. A graph of dependencies is created in which +each node corresponds to one item and directed eges lead from nodes to +those which must *precede* them on the link line. For example, the +graph + + C -> B -> A + +will lead to the link line order + + A B C + +The set of items placed in the graph is formed with a breadth-first +search of the link dependencies starting from the main target. + +There are two types of items: those with known direct dependencies and +those without known dependencies. We will call the two types "known +items" and "unknown items", respecitvely. Known items are those whose +names correspond to targets (built or imported) and those for which an +old-style <item>_LIB_DEPENDS variable is defined. All other items are +unknown and we must infer dependencies for them. + +Known items have dependency lists ordered based on how the user +specified them. We can use this order to infer potential dependencies +of unknown items. For example, if link items A and B are unknown and +items X and Y are known, then we might have the following dependency +lists: + + X: Y A B + Y: A B + +The explicitly known dependencies form graph edges + + X <- Y , X <- A , X <- B , Y <- A , Y <- B + +We can also infer the edge + + A <- B + +because *every* time A appears B is seen on its right. We do not know +whether A really needs symbols from B to link, but it *might* so we +must preserve their order. This is the case also for the following +explict lists: + + X: A B Y + Y: A B + +Here, A is followed by the set {B,Y} in one list, and {B} in the other +list. The intersection of these sets is {B}, so we can infer that A +depends on at most B. Meanwhile B is followed by the set {Y} in one +list and {} in the other. The intersection is {} so we can infer that +B has no dependencies. + +Let's make a more complex example by adding unknown item C and +considering these dependency lists: + + X: A B Y C + Y: A C B + +The explicit edges are + + X <- Y , X <- A , X <- B , X <- C , Y <- A , Y <- B , Y <- C + +For the unknown items, we infer dependencies by looking at the +"follow" sets: + + A: intersect( {B,Y,C} , {C,B} ) = {B,C} ; infer edges A <- B , A <- C + B: intersect( {Y,C} , {} ) = {} ; infer no edges + C: intersect( {} , {B} ) = {} ; infer no edges + +Once the complete graph is formed from all known and inferred +dependencies, we walk the graph with a series of depth-first-searches +in order to emit link items. When visiting a node all edges are +followed first because the neighbors must precede the item. Once +neighbors across all edges have been emitted it is safe to emit the +current node. + +If a single DFS returns to a node it previously reached then a cycle +is present. Cyclic link dependencies are resolved simply by repeating +one of the cycle entries at the beginning and end of the cycle +members. For example, the graph + + A <- B , B <- C , C <- A + +can be satisfied with the link item list + + A B C A + +When a node is reached a second time during the same DFS we make sure +its item has been emitted and then skip following its outgoing edges +again. + +The initial exploration of dependencies using a BFS associates an +integer index with each link item. When the graph is built outgoing +edges are sorted by this index. This preserves the original link +order as much as possible subject to the dependencies. + +*/ + +//---------------------------------------------------------------------------- +cmComputeLinkDepends +::cmComputeLinkDepends(cmTarget* target, const char* config) +{ + // Store context information. + this->Target = target; + this->Makefile = this->Target->GetMakefile(); + this->LocalGenerator = this->Makefile->GetLocalGenerator(); + this->GlobalGenerator = this->LocalGenerator->GetGlobalGenerator(); + + // The configuration being linked. + this->Config = config; + + // Enable debug mode if requested. + this->DebugMode = this->Makefile->IsOn("CMAKE_LINK_DEPENDS_DEBUG_MODE"); +} + +//---------------------------------------------------------------------------- +cmComputeLinkDepends::~cmComputeLinkDepends() +{ + for(std::vector<DependSetList*>::iterator + i = this->InferredDependSets.begin(); + i != this->InferredDependSets.end(); ++i) + { + delete *i; + } +} + +//---------------------------------------------------------------------------- +std::vector<cmComputeLinkDepends::LinkEntry> const& +cmComputeLinkDepends::Compute() +{ + // Follow the link dependencies of the target to be linked. + this->AddLinkEntries(-1, this->Target->GetOriginalLinkLibraries()); + + // Complete the breadth-first search of dependencies. + while(!this->BFSQueue.empty()) + { + // Get the next entry. + BFSEntry qe = this->BFSQueue.front(); + this->BFSQueue.pop(); + + // Follow the entry's dependencies. + this->FollowLinkEntry(qe); + } + + // Infer dependencies of targets for which they were not known. + this->InferDependencies(); + + // Display the constraint graph. + if(this->DebugMode) + { + fprintf(stderr, + "---------------------------------------" + "---------------------------------------\n"); + fprintf(stderr, "Link dependency analysis for target %s, config %s\n", + this->Target->GetName(), this->Config?this->Config:"noconfig"); + this->DisplayConstraintGraph(); + } + + // Compute the final set of link entries. + this->OrderLinkEntires(); + + // Display the final set. + if(this->DebugMode) + { + this->DisplayFinalEntries(); + } + + return this->FinalLinkEntries; +} + +//---------------------------------------------------------------------------- +int cmComputeLinkDepends::AddLinkEntry(std::string const& item) +{ + // Check if the item entry has already been added. + std::map<cmStdString, int>::iterator lei = this->LinkEntryIndex.find(item); + if(lei != this->LinkEntryIndex.end()) + { + // Yes.
