Now that the quick functions are separate from the object file format, there's no need to have elfread.c push a new entry on the objfile 'qf' list. Instead, this detail can be pushed into the DWARF reader. That is what this patch implements. I wasn't sure whether lazy reading still makes sense or not. It's still only used by ELF, and only in certain situations (like vfork, I think). It may not be carrying its weight, so we may want to consider removing this in the future. Also, I'm unclear on why the various indices are only used for ELF. This seems sub-optimal. However, I haven't tried to address that here. gdb/ChangeLog 2021-03-28 Tom Tromey <tom@tromey.com> * elfread.c (can_lazily_read_symbols): Move to dwarf2/read.c. (elf_symfile_read): Simplify. * dwarf2/read.c (struct lazy_dwarf_reader): Move from elfread.c. (make_lazy_dwarf_reader): New function. (make_dwarf_gdb_index, make_dwarf_debug_names): Now static. (dwarf2_initialize_objfile): Return void. Remove index_kind parameter. Push on 'qf' list. * dwarf2/public.h (dwarf2_initialize_objfile): Change return type. Remove 'index_kind' parameter. (make_dwarf_gdb_index, make_dwarf_debug_names): Don't declare.
