This introduces a new iterator and range adapter for iteration over the separate debug files of a given objfile. As in the current approach, the requested objfile is returned first, followed by the separate debug objfiles. gdb/ChangeLog 2019-04-09 Tom Tromey <tom@tromey.com> * symtab.c (lookup_global_symbol_from_objfile) (lookup_symbol_in_objfile_from_linkage_name): Use the iterator. * objfiles.h (class separate_debug_iterator): New. (class separate_debug_range): New. (struct objfile) <separate_debug_objfiles>: New method. (objfile_separate_debug_iterate): Don't declare. * objfiles.c (separate_debug_iterator::operator++): Rename from objfile_separate_debug_iterate. (objfile_relocate, objfile_rebase, objfile_has_symbols): Use the iterator. * minsyms.c (lookup_minimal_symbol_by_pc_section): Use the iterator.
FYI, this series of patches has broken builds with older versions of GCC (we've got 5.2.1 installed on our build system here). Multiple failures like:
/path/to/gdb/minsyms.c: In function 'bound_minimal_symbol lookup_minimal_symbol_by_pc_section(CORE_ADDR, obj_section*, lookup_msym_prefer)': /path/to/gdb/minsyms.c:724:8: error: types may not be defined in a for-range-declaration [-Werror] for (struct objfile *objfile : section->objfile->separate_debug_objfiles ())
