[clang] Disable avx512vlcd test on Arm 32-bit When clang is compiled with a more recent clang (that includes 5d7f324614d7a5c0de89cfe8295a9b2b7ef5d073), the code produced enforces 64-bit alignment on a type that is used during this test. For reasons not known yet, that type is not 64-bit aligned though you would normally expect it to be. See https://github.com/llvm/llvm-project/issues/172994. I would xfail this but I'm not 100% sure that it always fails. Memory layout may make it pass sometimes.
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.
Consult the Getting Started with LLVM page for information on building and running LLVM.
