You're right, this needs to account for all fixed arguments, not just the first
(guaranteed) one. NVIDIA seems to handle it where the fixed arguments are
passed using the regular ABI (can be indirect or direct) while the variadic
arguments are always direct. Is there an easy way to check if an argument is
part of the variadic set? Maybe if the argument number > number of arguments?
