This patch started as an attempt to replace ALL_SO_LIBS with an ordinary C++ iterator. However, then I tripped over the so_list_head define again, and decided to remove it as well. gdb/ChangeLog 2020-05-08 Tom Tromey <tom@tromey.com> * mi/mi-cmd-file.c (mi_cmd_file_list_shared_libraries): Update. * solib-svr4.c (svr4_fetch_objfile_link_map): Update. (enable_break): Update. * solib-frv.c (frv_fdpic_find_global_pointer): Update. (frv_fdpic_find_canonical_descriptor): Update. (frv_fetch_objfile_link_map): Update. * progspace.c (program_space::free_all_objfiles): Update. (program_space::solibs): New method. * progspace.h (struct program_space) <solibs>: New method. * solist.h (master_so_list): Don't declare. (ALL_SO_LIBS): Remove. * solib.h (so_list_head): Remove. (update_solib_list): Update comment. * solib.c (master_so_list): Remove.
