[llvm-dev] Core dump Compiling with clang sample

[mats petersson via llvm-dev]

I would start by looking at exactly what the `triple` is for your target.
It is plausible that the precise name&number of your system isn't supported
- I know nothing of Sparc support, just that (sometimes) you only need a
minor letter/digit away from the supported platform(s) to get this sort of
problem. Building Clang + LLVM with debug symbols and going back up the
call-stack to see exactly where it fell over would help - sometimes there's
even comments to help out there... :)

It's quite plausible, if you know enough about the processor architectures,
that you can pick a "nearby relative" and specify "-target=ABC" to work
around the problem. But without knowing WHAT you are running on, I doubt
anyone can give precise help.
