when I execute clang on llvm bitcode files, I get the following error: clang: error: unable to execute command: Aborted unsupported GC: vmkit UNREACHABLE executed at GCMetadata.cpp:87! 0 clang 0x09e9d5d9 llvm::sys::PrintStackTrace(_IO_FILE*) + 41 Stack dump: 0.

when I compile llvm-3.3 according to the instructions in vmkit's homepage the following error occurs: llvm-3.3.src/Release+Asserts/lib/libclangAST.a(VTableBuilder.o): In function `(anonymous namespace)::VCallAndVBaseOffsetBuilder::AddVCallOffsets(clang::BaseSubobject, clang::CharUnits)': VTableBuilder.cpp:(.text+0xc6c3): undefined reference to

I'm new to c++ programming and currently working on an llvm front-end development project. When I link the object files created by llc, my linker cannot locate the following functions. I know that these are standard c++ library functions but g++ cannot locate them. Now my question is that where are these functions defined and how can I link them with my object files, and actually what do they

[Resending as my previous message was sent to moderation. The list info page doesn't mention this is a subscriber only list] I'm trying to write a .so which will be loaded using dlopen and called using dlopen. The application is written in C and I want to use the LLVM C API jfrom it. Obviously it will end up calling C++ functions internally but as long as I expose a C API to the

Hello, I update my building scripts to build LLVM 4.0 RC1 (with clang, lldb, libc++, libc++abi, lld) on CentOS 6 and I got a lot of undefined symbols during linking LLDB. I'm using clang-3.9 and this configuration: -DLLVM_TARGETS_TO_BUILD="X86" -DCMAKE_BUILD_TYPE=Release -DCMAKE_C_COMPILER=/usr/bin/clang -DCMAKE_CXX_COMPILER=/usr/bin/clang++

In order to print unicode characters with llvm, I used setLocale in llvm ir: call i8* @setlocale(i32 6, i8* getelementptr inbounds ([1 x i8]* @pe, i32 0, i32 0)) nounwind where @pe is defined as follows: @pe = private unnamed_addr constant [1 x i8] zeroinitializer, align 1 However, I got the following error: *** glibc detected *** ./test/bin/executable: free(): invalid next size

Hi Jack, Are you packaging all the static libraries that lld produces as part of the package ? PS : When I build on x86_64, I only get a 9M image for lld.

Hi Pavel, thank you for you response. objdump -T showed that there are no symbols defined in liblldb.so. After few compilations I found that problem is with linking with LLD (-DLLVM_ENABLE_LLD=ON) without the directive everything is ok.

When lld-3.4 is added to the tools directory of the llvm source tree as lld, the resulting cmake build produces a huge number of static libs and bloats the overall package from... -rw-r--r-- 1 root wheel 86361440 Nov 19 21:09 llvm34_3.4-0_darwin-x86_64.deb to -rw-r--r-- 1 root wheel 495257452 Nov 19 20:49 llvm34_3.4-0_darwin-x86_64.deb Is this a known issue with the initial release of

Hi, I'm currently working on one of my team's project to build LLVM full clang toolchain (Clang, libcxx, libcxxabi) on a CentOS machine. Previously we compiled our codebase with llvm-toolset-7/clang++, which by default takes stdlibc++ to compile and link. And now we'd like to switch to use LLVM clang with libc++. I have built libc++ and libc++abi from source (5.0.1 release) and set

While considering statically linking against libc++ (and other runtime libraries from LLVM), I rebuilt LLVM 4.0 with -DBUILD_SHARED_LIBS=OFF. There are still some .so's in llvm/lib, and only one of them seems to exist exclusively as a DSO (libLTO). There's also livLLVMLTO.a, but I doubt LTO is used after linking a binary so this just looks odd to an uninformed LLVM outside and not

Hi Lang, I am on Ubuntu 14.04. I am building ToT: llvm, clang, polly, lld, compiler-rt, libcxx, libcxxabi. The build compiler is: clang+llvm-3.7.0-x86_64-linux-gnu-ubuntu-14.04 The failures show up during "make check-all". My cmake command was: cmake -G 'Unix Makefiles' -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/w/c/org -DLLVM_TARGETS_TO_BUILD:STRING=all

Looks like your static library is not even pulled into the link command so the static library is not even in the snapshot. From the link command in the snapshot, the static library is not on the command line from snapshot: /Applications/Xcode-11.3.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ld -Z -demangle -object_path_lto

Hi Tobias The problem is that your static archive has a SYMDEF that is empty, so linker thinks the static library provided doesn't contain any symbol. The reason for that is you are using the `ranlib` from Xcode, which is too old to understand the new bitcode object files produced by llvm 10. There are lots of ways to fix that: * The standard way to create static library on macOS is to use

After re-cmaking and rebuilding everything from scratch, I'm seeing failures in MCJIT. It this something known or expected? I build LLVM/clang with pre-packaged clang-3.7.0, with "-stdlib=libc++". Example failure: /w/bld/org/./bin/lli -remote-mcjit -mcjit-remote-process=/w/bld/org/./bin/lli-child-target /w/src/llvm.org/test/ExecutionEngine/MCJIT/remote/eh.ll -- Exit Code:

Hey, I need to approximate the run-time objects of a program. It is up to the compiler's front-end to make the decision on how to translate the new-expressions in C++, however. This obfuscates the way to figure out dynamically allocated program points in the middle-end (e.g. LLVM). So I am wondering if there is any general way to do so? Does the front-end provide any hint(s) to the

This is usually a problem that is not using llvm-ar. I cannot reproduce this problem with either llvm 10.0 or TOT version. Which linker version are you using? You can also try pass "-Wl,-debug_snapshot" to the command where the error produces and then locate the "*.ld-snapshot" in /tmp directory and attach that as a reproducer.
