The buidbot [flang-aarch64-libcxx](https://lab.llvm.org/buildbot/#/builders/89) is currently failing with an ABI issue. The suspected reason is that LLVMSupport.a is built using libc++, but the unittests are using the default C++ standard library, libstdc++ in this case. This predefined `llvm_gtest` target uses the LLVMSupport from `find_package(LLVM)`, which finds the libc++-built LLVMSupport. To fix, store the `LLVM_ENABLE_LIBCXX` setting in the LLVMConfig.cmake such that everything that links to LLVM libraries use the same standard library. In this case discussed in https://github.com/llvm/llvm-zorg/pull/387 it was the flang-rt unittests, but other runtimes with GTest unittests should have the same issue (e.g. offload), and any external project that uses `find_package(LLVM)`.
The LLVM Compiler Infrastructure
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called "LLVM". This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
