LibreSSL – the first 30 days

Are you saying LLVM has a problem with producing unaligned accesses, as in you can't prevent this?

That would be pretty awful; on how many architectures do they still cause exceptions?

ARM says the ARMv6 was the first architecture to support this (http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc....).

No, not with producing unaligned accesses, a problem with unaligned accesses in the LLVM code itself.

They're worked around by forcing alignment at the cost of performance if I remember correctly, or in some cases, they're not and cause LLVM to fail.

The alignment problems may be unique to the SPARC backend of LLVM, but I don't recall the specifics.
