2013-01-02Move all of the header files which are involved in modelling the LLVM IRChandler Carruth
into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project. I'll be committing updates to Clang, DragonEgg, and Polly momentarily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171366 91177308-0d34-0410-b5e6-96231b3b80d8

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
2009-08-31Fix some nasty callgraph dangling pointer problems in Chris Lattner
argpromotion and structretpromote. Basically, when replacing a function, they used the 'changeFunction' api which changes the entry in the function map (and steals/reuses the callgraph node). This has some interesting effects: first, the problem is that it doesn't update the "callee" edges in any callees of the function in the call graph. Second, this covers for a major problem in all the CGSCC pass stuff, which is that it is completely broken when functions are deleted if they *don't* reuse a CGN. (there is a cute little fixme about this though :). This patch changes the protocol that CGSCC passes must obey: now the CGSCC pass manager copies the SCC and preincrements its iterator to avoid passes invalidating it. This allows CGSCC passes to mutate the current SCC. However multiple passes may be run on that SCC, so if passes do this, they are now required to *update* the SCC to be current when they return. Other less interesting parts of this patch are that it makes passes update the CG more directly, eliminates changeFunction, and requires clients of replaceCallSite to specify the new callee CGN if they are changing it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80527 91177308-0d34-0410-b5e6-96231b3b80d8

2008-09-06When PruneEH turned an invoke into an ordinaryDuncan Sands
call (thus changing the call site) it didn't inform the callgraph about this.

2008-09-05Delete the removeCallEdgeTo callgraph method,Duncan Sands
because it does not maintain a correct list of callsites. I discovered (see following commit) that the inliner will create a wrong callgraph if it is fed a callgraph with correct edges but incorrect callsites. These were created by Prune-EH, and while it wasn't done via removeCallEdgeTo, it could have been done via removeCallEdgeTo, which is an accident waiting to happen. Use removeCallEdgeFor instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55859 91177308-0d34-0410-b5e6-96231b3b80d8
