Hi Kevin, Koffie, We will start migrating to ORC for next release, but for now, this release > invoke delete after remove right? MCJIT's removeModule method does not delete the module. You'll need to do that manually. OrcMCJITReplacement is a bug-for-bug compatible implementation of MCJIT using ORC c...

I'm on llvm 3.8.1 and was wondering if there's a memory leak in the removeModule impl of mcjit. In the tutorial http://llvm.org/releases/3.8.1/docs/tutorial/LangImpl4.html a module is removed from the Jit by invoking removeModule. According to the tutorial: "Its API is very simple:: addModule adds an LLVM IR module to the JIT, making its functions available for execution;

Hi, What other options do I have to reduce JIT time for large amount of code? - setting optimization level to none helps a lot - enabling FastISel doesn't seem to help much Thanks! -------------- next part -------------- An HTML attachment was scrubbed...

Hi Koffie, I'd highly recommend switching to ORC from MCJIT. It is much more flexible when it comes to memory-management. 1. I took the approach of 1 execution engine with multiple modules (I'm not > removing modules once they have been added). During profiling, I noticed > that the memory u...

...const llvm::Twine & N, llvm::Module * M) Line 116 C++ caused it to be set to False. So do I need to trace into all the Function bases classes and find out where it is set to false? or do I need to fix the Storage address computation in the else part?

Hi, I'm trying to speed up the JIT time with llvm (3.9.1). So far i've implemented the object cache, used FastISel and disabled optimizations. Jit time is still too slow for my purpose (I do have a lot of code to Jit). http://llvm.org/docs/ProgrammersManual.html#threads-and-the-jit states that we can invoke ExecutionEngine::getPointerToFunction() concurrently. This function was replaced

Did something changed in llvm::User::new between 3.7.1 and 3.8.0 ? I found a bug in llvm ?

Hi all, I'm building a runtime that can jit and execute code. I've followed the kaleidoscope tutorial and had a couple of questions. Basically I have a pre-compiler that compiles the code to cache objects. These cached objects are then persisted and used to reduce Jit compile time. 1. I took the approach of 1 execution engine with multiple modules (I'm not removing modules once

Hi all, I'm trying to add pre-compiled object cache to my run-time. I've implemented the object cache as follow: class EngineObjectCache : public llvm::ObjectCache { private: std::unordered_map<std::string, std::unique_ptr<llvm::MemoryBuffer>> CachedObjs; public: virtual void notifyObjectCompiled(const llvm::Module *M, llvm::MemoryBufferRef Obj) { auto id =

Hi all, I have the following code: [use llvm to generate ir_func() ] in side the ir_func() there's a call to a native cpp function that throws an exception. (Just imagine changing the fibonacci example and calling a native c++ func that throws inside the fibonacci body) I can't seem to catch "foreign" exception or any exception using the following pseudo code: try { // cast

...ction and deleting it? I'm using visual studio 2015 update1, and could not find any known issue regarding heaps. I'm at a point where I'm suspecting my compiler. But its weird that the same compiler works fine with 3.7.1 any ideas would be appreciated On Wed, Feb 24, 2016 at 9:10 AM, koffie drinker <gekkekoe at gmail.com> wrote: > > I recently upgraded from llvm 3.7.1 to a pre release of llvm (3.8.0rc2) in > order to test some issues regarding bug 24233. > After upgrading I starting to see heap corruption messages in vs 2015 sp1 > when my program exits. > &qu...

Hi, I'm experiencing a weird problem with llvm 3.7(rc2/rc3) that did not occur in llvm 3.6.2 I created a bug for it: https://llvm.org/bugs/show_bug.cgi?id=24521 I'm building a app where multiple code gen can happen in parallel. The documentation state that I need to use separate context. Each thread has it's own context. When code generating a constant number I use the *InContext()

I recently upgraded from llvm 3.7.1 to a pre release of llvm (3.8.0rc2) in order to test some issues regarding bug 24233. After upgrading I starting to see heap corruption messages in vs 2015 sp1 when my program exits. "HEAP[ConsoleEngine.exe]: Invalid address specified to RtlValidateHeap( 0000000000290000, 0000000000318698 )" Initially I only got it in Release build. Debug build seems

...s, it seems that I have to have a execution engine per module. Is this still the case ? (the posting were quite old). Is there a difference between mcjit and orc in this case?

Hi, I am wondering what the status of Clang++ and LLVM on the Windows platform ? When I last saw what the state was there was not proper linking and more recently heard that the Structured Exception Handling was not working. The status page seems somewhat out of date ? Many thanks in advance, Aaron

Hi- just wondering, what would be the best quality rating to use to fit lots of music into 10GB of HD space. The audio quality has to be high enough for it to sound good when played through PA systems (for when my college is stupid enough to forget to hire a DJ, or when the realise the DJ they always hire can't use a mixing desk properly) ranging from a functional PA system thats stuck in the
