This patch finally changes gdb so that an objfile can have multiple sources of partial symbols (or mixed partial symbols and other kinds of indices). This is done by having each symbol reader create its own psymbol_functions object and add it to the 'qf' list in the objfile. gdb/ChangeLog 2021-03-20 Tom Tromey <tom@tromey.com> * xcoffread.c (xcoff_initial_scan): Create partial symtabs. * symfile.c (syms_from_objfile_1, reread_symbols): Update. * psymtab.h (make_psymbol_functions): Don't declare. * psymtab.c (make_psymbol_functions): Remove. (maintenance_print_psymbols): Update. * psympriv.h (struct psymbol_functions): Add no-argument constructor. * objfiles.h (struct objfile) <reset_psymtabs>: Remove. <partial_symtabs>: Remove. * mdebugread.c (mdebug_build_psymtabs): Create partial symtabs. * elfread.c (read_partial_symbols): Update. (elf_symfile_read): Remove check for existing partial symbols. Don't clear "qf". * dwarf2/read.c (dwarf2_has_info): Remove check for existing partial symbols. (dwarf2_build_psymtabs): Add psymbol_functions parameter. Create partial symtabs. * dwarf2/public.h (dwarf2_build_psymtabs): Add psymbol_functions parameter. * dbxread.c (dbx_symfile_read): Create partial symtabs. * ctfread.c (elfctf_build_psymtabs): Create partial symtabs.
