similar to: [LLVMdev] Memory leaks in LLVM on linux

Hi, I'm Ryo Onodera. This is my first post to this mailing list. Fist, thanks for creating a great library! We're using LLVM to support JIT in Rubinius (an alternative implementation of Ruby, a dynamic programming language). I'm submitting a small patch for a minor issue. It solves still-reachable leak warnings from Valgrind. Example warnings are shown at the end of this mail. As

I've hit this weird compiler error when building llvm/clang $ clang --version clang version 2.9 (trunk 125254) Target: x86_64-apple-darwin10 Thread model: posix Source rev is 125326 $ make llvm[1]: Compiling APFloat.cpp for Release build llvm[1]: Compiling APInt.cpp for Release build llvm[1]: Compiling APSInt.cpp for Release build llvm[1]: Compiling Allocator.cpp for Release build llvm[1]:

Hi, We use LLVM libraries to compile C++ code and noticed slow downs when multiple threads of a process were compiling at once. *perf *indicated that most of the CPU time was spent in a spin lock, which was being locked/unlocked from llvm::PassRegistry::getPassInfo(). We read the relevant LLVM code and found out that PassRegistry is a ManagedStatic and is shared among all threads in case of a

I’ve almost finished a patch to add back in either out of line destructors or anchor methods. We seem to use one or the one, relatively inconsistently. What i’ve gone for is that if a class already had an inline destructor then i left it alone and added an anchor method. Otherwise I added an out of line destructor. Now if I compile Instructions.cpp with -Wweak-vtable, the only warnings given

Hi, I'm trying to build llvm on a Solaris/Sparc machine. I get many undefined symbols during the link phase of opt. The link command being run is below. It is identical to the link command that gets run and works on an x86 host.

With the patch alone, the void* overload of addGarbageObject() was being used by MDNode::getTemporary(), so I had to cast the object as an MDNode*: diff --git a/lib/IR/Metadata.cpp b/lib/IR/Metadata.cpp

There aren't any leaks to be had there, since they're allocated in a custom allocator. They're

Right, I'm suggesting we keep llvm_shutdown() for users who want this control, but also destroy still-live ManagedStatic instances if llvm_shutdown() is not called. This helps in the case where there is not a clear time when llvm_shutdown() can be called, especially given that LLVM cannot be resurrected in the same process due to current limitations in the pass registry, and perhaps

I'm curious about the design rationale for how ManagedStatic instances are cleaned up, and I'm hoping someone can shed some light on it. Currently, ManagedStatic objects are cleaned up when llvm_shutdown() traverses the global list of initialized objects and calls destroy() on each. This leads to two questions: 1. An assertion enforces that the objects are deleted in reverse order of
