            Bug ID: 34256
           Summary: clang segmentation fault for OpenMP target
           Product: clang
           Version: 5.0
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs
          Assignee: unassignedclangbugs at nondot.org
          Reporter: siegmar.gross at informatik.hs-fulda.de

loki introduction 119 llc -version
LLVM (http://llvm.org/):
  LLVM version 5.0.0svn-r311291
  Optimized build.
  Default target: x86_64-unknown-linux-gnu
  Host CPU: haswell

  Registered Targets:
    nvptx   - NVIDIA PTX 32-bit
    nvptx64 - NVIDIA PTX 64-bit
    x86     - 32-bit X86: Pentium-Pro and above
    x86-64  - 64-bit X86: EM64T and AMD64


"libomptarget" is disabled at the moment, but nevertheless the compiler
shouldn't generate a segmentation fault. I've already reported the problem for
the trunk (Bug 34104) and I would be grateful if somebody can fix the error
before version 5.0 will be released. The program is available with Bug 34104.

clang-5.0: error: cannot find libdevice for . Provide path to different CUDA
installation via --cuda-path, or pass -nocudalib to build without linking with
libdevice.
