[LLVMdev] Possible memory leak in LLVM 2.5
...on a game engine. Haven't updated to 2.7 yet, but I do intend to. When checking for memory leaks I found that each time I was calling EE->runFunction after creating a stub function to execute an event, all the pass information was being repeatedly added to PMDataManager. I have changed addAnalysisImplsPair to the following, which seems to have no side effects with what I am doing. Prior to that, AnalysisImpls contained thousands of entries and each time the vector gets realloced to accommodate more entries we lose a bigger chunk of memory. void addAnalysisImplsPair(const PassInfo *PI, Pass *P...

[LLVMdev] getAnalysis()
...DDataStructures>(); } Then I try to use it as follows: bool MyPass::doInitialization(Module &M) { TDDataStructures &dsgraph = getAnalysis<TDDataStructures>(); return false; } When I run my pass via opt, I get the following assertion error: Assertion failed: i != AnalysisImpls.size() && "getAnalysis*() called on an analysis that we not " "'required' by pass!", file ../../include/llvm/Pass.h, line 170 Any idea what I am doing wrong? Thanks, Scott Mikula

[LLVMdev] Prevent unbounded memory consuption of long lived JIT processes
This series of patches address several issues causing memory usage to grow indefinetely on a long lived process. These are not convenional leaks -- memory would have been freed when the LLVM context or/and JIT engine is destroyed -- but for as long as they aren't the memory is usage effectively ubounded. The issues were found using valgrind with '--show-reachable=yes' option: 1.
