[Llvm-bgq-discuss] linker errors with llvm/current/bin/bgclang++

Ah, that would certainly explain it.

Next up, clang is crashing for me with the error shown below.  The
full stack trace, precompiled source, and run script are at

    http://naml.us/random/clang

Have you seen similar things before, or know any workarounds?

Thanks,
Geoffrey

At -O3 (which enables autovectorization), bgclang will generate QPX vector instructions; those QPX instructions are not supported by the Power 7 CPU in the login node. You'll need to submit a job and run on the compute nodes.
