<pre>loki introduction 119 llc -version
LLVM (<a href="http://llvm.org/">http://llvm.org/</a>):
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 (<a class="bz_bug_link
bz_status_NEW "
title="NEW - clang segmentation fault for OpenMP target pragma"
href="show_bug.cgi?id=34104">Bug 34104</a>) and I would be grateful if somebody can fix the error
before version 5.0 will be released. The program is available with <a class="bz_bug_link
