[LLVMdev] Question about volatile variable in X86 backend

It looks like that test is actually trying to find out whether GCC
knows any special semantics for __fprintf_chk rather than whether it
can handle volatiles.

Clang doesn't do anything in particular with that function so it
"fails". It's compiling the file correctly as far as I can see.

Cheers.
