similar to: [LLVMdev] Problems with parallelizing lli

Hi, I am trying to parallize the lli interpreter (code: http://pastebin.com/6iuHNH3Q). I am using ubuntu 12.04 with llvm version 3.1. Each thread uses a seperate LLVMContext, however the interpreter continues to crash. Error msg: ..../include/llvm/Support/Mutex.h:116: bool llvm::sys::SmartMutex<true>::release(): Assertion `((recursive && acquired) || (acquired == 1)) &&

I am trying to figure out how to free up some memory that seems to be lost when running valgrind under our internal application. The stack traces I get are: ==19966== 4 bytes in 1 blocks are still reachable in loss record 1 of 12 ==19966== at 0x402569A: operator new(unsigned int) (vg_replace_malloc.c:255) ==19966== by 0x5D9BBE8: void* llvm::object_creator<llvm::PassRegistry>()

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

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

I committed: r224058 = 966942da9e68b59c31ce770e7f94c55a63482c6b r224060 = da75f7277e3a129aed8ef8aa4e0d84de40b76fd4 r224061 = f88e4c8e9171045454b2c8e05054c2af8da3fe4f Let me know if somehow you're still hitting the problem. r224061 removes leak detection entirely from `MachineInstr`. There aren't any leaks to be had there, since they're allocated in a custom allocator. They're

The `Metadata`/`Value` split (PR21532) landed in r223802 -- at least, the C++ side of it. This was a rocky day, but I suppose that's what I get for failing to stage the change in smaller pieces. As of r223916 (lldb), I'm not aware of any remaining (in-tree) breakage, so if I've missed some problem in the sea of buildbot errors, please flag me down. I'll follow up soon with

Hi, I'm trying to describe the patterns for the m68k instructions ADD and ADDA when used with a data register operand for the source. Basically, ADD operates on anything but address registers and immediates, and ADDA works on address registers only so I'm going to need both instructions in my instruction set. These are the two problematic definitions; by themselves they produce the

Hello all, For the past couple of months I've been writing a new llvm backend for Renesas RL78 MCU: https://www.renesas.com/eu/en/products/microcontrollers-microprocessors/rl78.html The software manual which contains all there is to know about RL78 is available here: https://www.renesas.com/us/en/doc/products/mpumcu/doc/rl78/r01us0015ej0220_rl78.pdf The motivation behind this is the

I was thinking about [Bug 3099]... in that while it's easy to get a 2-3x speed for the average app using parallel scans, the upper and lower bounds on that speed increase could be <1x in a worst case (very unlikely, but with primitive or constrained (in a container or VM) HW, the chances are raised. Better, with less std. deviation, I believe, might be to move I/O calls to all being AIO

Hi David, Thank for very much for your reply! I got a reply on the clang mailing list in April from Dmitri: http://lists.llvm.org/pipermail/cfe-dev/2020-April/065115.html and following his advice “attaching pragmas as attributes to functions” I managed to do it, it was actually quite easy. >>Compatibility with an existing compiler is usually compelling - are the compilers you're

Hi All Some background first I have been asked to set up an environment involving three machines 1. A windows 2000 client 2. A Solaris 8 E450 / NIS client 3. An SGI IRIX fileserver/ NIS server holding user home directories The E450 NFS mounts the SGI and users have their home directories on the SGI. When users want to test their application software they ssh from their windows client into

Hi everybody, I have installed mongrel and mongrel cluster in a new linux box .... at the end of the day I was able to lunch mongrel (mongrel_rails start -e production) and all is working fine with. However, when I tried to set a mongrel cluster the command mongrel_rails cluster::start get the following output : starting port 8000 starting port 8001 starting port 8002 But when I lunched the

Dear All, We are in the process of evaluating Samba to provide SMB access to unix file storage for a few hundred PC's. One of our tests is to save a Word97 document - something that has caused various PCNFS clients problems in the past. While saving the document the client stopped and said something like connection lost, or seesion closed, and the drives mapped from the samba box

Hi, I am running my code in a cluster at Arizona State University. I have a huge climate data, 66000 X 500 I am not sure if I can find correlation of such a huge data in the cluster. Normally I allocate 20000M and operate on 5 X 20000. Even this is taking lot of time. Is there any way I can find cl = cor(cdata) utilizing the computers in the clusters(I am using 32 nodes ). I am using the
