The first is clang generates a preamble (that is always executed) to stack xmm registers. This causes a ILLOP on the x86_64 softmmu tests as SSE isn't enabled. The second is the inline assembler in test-i386.c breaks clangs compiler and I don't know how to fix it. Even with Theodore's patch series (D5741445-7EFD-4AF1-8DB2-E4AFA93CBB1A@icloud.com) I still get compiler failures. For now lets just skip clang and allow it to fall back to the containers which we know have compilers which work.
