similar to: [LLVMdev] Seg Fault when creating an execution engine

Oops, missed initializing some stuff. Added: LLVMLinkInMCJIT(); LLVMInitializeNativeTarget(); LLVMInitializeNativeAsmPrinter(); LLVMInitializeNativeAsmParser(); Now it crashes in LLVMGetFunctionAddress(). Hmm.

Or do you mean I need to load the module into memory before calling LLVMGetBitcodeModuleInContext2? > Yes, you need to load the module into memory first. > LLVMCreateMemoryBufferWithContentsOfFile will do that for you.

Hello, [Using LLVM r155315, according to `svn log | head`] I am experimenting with programatically building and jitting functions in a module, and I seem to be coming across a crash in some generated code. Using the llvm-c interface I build up the module which dumps like this: ; ModuleID = 'MyModule' target datalayout = "i686-apple-darwin11" target triple =

Hi David, I'm not certain, but to me the "LLVMSetTarget(module, "i686-apple-darwin11");" line looks suspicious. I'm not familiar with all the ins and outs of how target triples get handled, but it looks to me like that's requesting 32-bit code. I think that if you omit that line completely then the target will be inferred from the execution environment. My best

Hi, I'm attempting to use MCJIT with the C interface with llvm-3.9.0, and it doesn't seem to work. This code is derived from Paul Smith's example code: int main(int argc, char const* argv[]) { LLVMModuleRef mod = LLVMModuleCreateWithName("my_module"); LLVMTypeRef param_types[] = {LLVMInt32Type(), LLVMInt32Type()}; LLVMTypeRef ret_type =

Hi all, I have some old code using the JIT via the LLVM-3.0-C API. I want to upgrade to newer versions of LLVM. As a simple example I wrote a C program that creates the following function and calls it: ; ModuleID = 'round-avx.bc' target triple = "x86_64-pc-linux-gnu" define void @round(<8 x float>*) { _L1: %1 = load <8 x float>* %0 %2 = call <8 x

Current llvm-gcc-4.2 for trunk and the 2.6 release is unable to build the i386 multilib for the x86_64-apple-darwin target. The attached patch provides this support. Can we get this into the 2.6 release and trunk? Jack -------------- next part -------------- Index: gcc/config/i386/t-darwin64 =================================================================== ---

Hi everyone, I encountered a strange bug when I tried to compile openssl (https://www.openssl.org/) with clang and llvm-ar on a 64-bit OS X. I changed the openssl makefile to use llvm-ar instead of simply ar. Openssl will then create two static libraries libssl.a and libcrypto.a. The problem occurs when it tries to link these two static libraries to the final openssl executable. I get the

Hi, I am trying to run an LLVM analysis on a C++ program that calls qsort(), using the LLVM interpreter (lli --force-interpreter). The code is the qsort_large.c file in the MiBench benchmark suite. If I comment the qsort() call, the execution works fine. If I uncomment the qsort() call, I run into a segmentation fault error as follows: 0  lli             0x0000000000d35c6f 1  lli

Never had much trouble building on the Mac until this round. Trying to build 7.4p1 with openssl 1.0.2j on a MacOSX 10.12.2/3 machine. gcc --version returns clang-800.0.42.1. This is the latest Xcode. Builds fine. Upon running sshd, it seg faults with this in the logs: assertion failed 16C67: libsystem_trace.dynlib+76912 [5BD4ECD4-75CA-38EA-AF5C-B481C15955F8]: 0x0 If I run the tests, it

LLVMers, 2.6 pre-release1 is ready to be tested by the community. http://llvm.org/prereleases/2.6/ You will notice that we have quite a few pre-compiled binaries (of both clang and llvm-gcc). We have identified several bugs that will be fixed in pre-release2, so please search the bug database before filing a new bug. If you have time, I'd appreciate anyone who can help test the

Kostya, I took a quick stab at patching libFuzzer for Apple, but so far I'm thinking something else is incorrect. Patch is attached but when I went to reproduce the examples, the toy example went fine, but with PCRE and Heartbleed I noticed the coverage statistics were pretty poor, and didn't find anything. Admittedly I moved onto Heartbleed pretty quickly so PCRE probably isn't the

This is a bit premature to be considered a code review, but given how unfamiliar I am with SelectionDAG (& that I'm seeing somewhat more 'interesting' results compared to my change to FastISel) I wanted to get a bit of feedback to see if I was on the right track or had missed any obvious cases. I've attached my patch in progress (including a modification to the existing test
