[llvm-dev] llvm-7.0.0rc2: Segmentation fault with a certain combination of options
Hi, today I've installed llvm-7.0.0rc2. Unfortunately, I still get the error that I've reported in Bug 38073 and for llvm-7.0.0rc1 (I'm still waiting for an approval or disapproval from the llvm-bugs list moderator). Therefore, I try this list today. loki introduction 108 clang -v clang version 7.0.0 (tags/RELEASE_700/rc2 340514) Target: x86_64-unknown-linux-gnu Thread model: posix InstalledDir: /usr/local/llvm-7.0.0/bin Found candidate GCC installation: /usr/lib64/gcc/x86_64-suse-linux/4.8 Selected GCC installation: /usr/lib64/gcc/x86_64-suse-linux/4.8 Candidate multilib: .;@m64 Candidate multilib: 32;@m32 Selected multilib: .;@m64 Found CUDA installation: /usr/local/cuda-9.0, version 9.0 loki introduction 109 The problem occurs with a certain combination of options (-mllvm -polly-parallel -mllvm -polly-vectorizer=stripmine).
