Yes, I agree that this is the way to go. Particularly, once we've read
a symtab in we should never need the corresponding psymtab again. Of
course, there are more partial symbols than minimal symbols; and
symbols take more memory than partial symbols. So it's not trivial.
By the way, I noticed something very interesting today. SGI apparently
had DWARF-2 extensions including a .debug_typenames section (and var,
func, weak names) to expand upon the concept of .debug_pubnames. We
could make GCC generate those and then use them to build psymtabs, I
bet. That would speed up load time a lot.
Oh well, something else for the List.
