* Reapply 80278Bruno Cardoso Lopes2009-09-014-45/+71
| | | | | | | | | Add MO flags to simplify the printing of relocations. Remove the support for printing large code model relocs (which aren't supported anyway). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80691 91177308-0d34-0410-b5e6-96231b3b80d8

* Preparation for Optimal Edge Profiling:Andreas Neustifter2009-09-011-1/+9
| | | | | | | | Add statistics for regular edge profiling, this enables the comparation of the number of edges inserted by regular and optimal edge profiling. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80668 91177308-0d34-0410-b5e6-96231b3b80d8
* Preparation for Optimal Edge Profiling:Andreas Neustifter2009-09-011-1/+8
| | | | | | | | | | Optimal edge profiling is only possible when blocks with no predecessors get an virtual edge (BB,0) that counts the execution frequencies of this function-exiting blocks. This patch makes the necessary changes before actually enabling optimal edge profiling. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80667 91177308-0d34-0410-b5e6-96231b3b80d8
* Preparation for Optimal Edge Profiling:Andreas Neustifter2009-09-011-0/+228
| | | | | | | | | This adds a pass to verify the current profile against the flow conditions. This is very helpful when later on trying to perserve the profiling information during all passes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80666 91177308-0d34-0410-b5e6-96231b3b80d8
* Change CallGraphNode to maintain it's Function as an AssertingVHChris Lattner2009-09-014-45/+38
| | | | | | | | | | | | | 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

* Clean up LSDA name generation and use for SJLJ exception handling. ThisJim Grosbach2009-09-017-34/+56
| | | | | | | | | | | | makes an eggregious hack somewhat more palatable. Bringing the LSDA forward and making it a GV available for reference would be even better, but is beyond the scope of what I'm looking to solve at this point.

| | | | | | | | | | | | | | | SCEVUnknowns, as the non-SCEVUnknown cases in the getSCEVAtScope code can also end up repeatedly climing through the same expression trees, which can be unusably slow when the trees are very tall. Also, add a quick check for SCEV pointer equality to the main SCEV comparison routine, as the full comparison code can be expensive in the case of large expression trees. These fix compile-time problems in some pathlogical cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80623 91177308-0d34-0410-b5e6-96231b3b80d8

* Free the constants that have no uses in ~LLVMContext.Edwin Török2009-08-314-4/+31
| | | | | | | | | | | | This fixes leaks from LLVMContext in multithreaded apps. Since constants are only deleted if they have no uses, it is safe to not delete a Module on shutdown, as many single-threaded tools do. Multithreaded apps should however delete the Module before destroying the Context to ensure that there are no leaks (assuming they use a different context for each thread). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80590 91177308-0d34-0410-b5e6-96231b3b80d8

* Step #1 to giving Callgraph some sane invariants. The problems with callgraphChris Lattner2009-08-312-27/+170
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
