testcase .ll
When built with expensive checks,
opt -globalopt paq8p.bc -disable-output
barfs due to taking the address of the first
element of an empty vector. It happens here:
2216 if (Constant *C = ConstantFoldCall(Callee, &Formals[0],
2217 Formals.size())) {
This kind of problem was fixed elsewhere by
introducing methods that take iterators. It
looks like the constant methods need the same
treatment. The above code would then become
if (Constant *C = ConstantFoldCall(Callee, Formals.begin(),
Formals.end()) {
