2010-01-22Stop building RTTI information for *most* llvm libraries. NotableChris Lattner
missing ones are libsupport, libsystem and libvmcore. libvmcore is currently blocked on bugpoint, which uses EH. Once it stops using EH, we can switch it off. This #if 0's out 3 unit tests, because gtest requires RTTI information. Suggestions welcome on how to fix this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94164 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-10Fix DenseMap iterator constness.Jeffrey Yasskin
This patch forbids implicit conversion of DenseMap::const_iterator to DenseMap::iterator which was possible because DenseMapIterator inherited (publicly) from DenseMapConstIterator. Conversion the other way around is now allowed as one may expect. The template DenseMapConstIterator is removed and the template parameter IsConst which specifies whether the iterator is constant is added to DenseMapIterator. Actually IsConst parameter is not necessary since the constness can be determined from KeyT but this is not relevant to the fix and can be addressed later.

2009-09-01Change CallGraphNode to maintain it's Function as an AssertingVHChris Lattner
for sanity. This didn't turn up any bugs. Change CallGraphNode to maintain its "callsite" information in the call edges list as a WeakVH instead of as an instruction*. This fixes a broad class of dangling pointer bugs, and makes CallGraph have a number of useful invariants again. This fixes the class of problem indicated by PR4029 and PR3601. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80663 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-31Step #1 to giving Callgraph some sane invariants. The problems with callgraphChris Lattner
stem from the fact that we have two types of passes that need to update it: 1. callgraphscc and module passes that are explicitly aware of it 2. Functionpasses (and loop passes etc) that are interlaced with CGSCC passes by the CGSCC Passmgr. In the case of #1, we can reasonably expect the passes to update the call graph just like any analysis. However, functionpasses are not and generally should not be CG aware. This has caused us no end of problems, so this takes a new approach. Logically, the CGSCC Pass manager can rescan every function after it runs a function pass over it to see if the functionpass made any updates to the IR that affect the callgraph. This allows it to catch new calls introduced by the functionpass. In practice, doing this would be slow. This implementation keeps track of whether or not the current scc is dirtied by a function pass, and, if so, delays updating the callgraph until it is actually needed again. This was we avoid extraneous rescans, but we still have good invariants when the callgraph is needed. Step #2 of the "give Callgraph some sane invariants" is to change CallGraphNode to use a CallBackVH for the callsite entry of the CallGraphNode. This way we can immediately remove entries from the callgraph when a FunctionPass is active instead of having dangling pointers. The current pass tries to tolerate these dangling pointers, but it is just an evil hack. This is related to PR3601/4835/4029. This also reverts r80541, a hack working around the sad lack of invariants. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80566 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-31Fix PR4834, a tricky case where the inliner would resolve anChris Lattner
indirect function pointer, inline it, then go to delete the body. The problem is that the callgraph had other references to the function, though the inliner had no way to know it, so we got a dangling pointer and an invalid iterator out of the deal. The fix to this is pretty simple: stop the inliner from deleting the function by knowing that there are references to it. Do this by making CallGraphNodes contain a refcount. This requires moving deletion of available_externally functions to the module-level cleanup sweep where it belongs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80533 91177308-0d34-0410-b5e6-96231b3b80d8
