Is there a reason not to just return void_type_node directly from
lto_read_unspecified_parameters_DIE? I believe that DWARF doesn't
have a "void" type (using a null type pointer to indicate void in
things like "void *") and, in any case, "void" is certainly not a
valid parameter type. So, at the risk of being a bit cute, you could
probably just return void_type_node directly, bypassing the cookie.
I did consider that, but decided that it was more robust and less
confusing to use the cookie than rely on punning some other object with
something other than its normal meaning. (Not that GCC isn't already
full of that sort of stuff, but I don't need to add to it....)
