Currently, the storage for partial symtabs is attached to the objfile. Ultimately, though, this direct assocation will be removed, and the storage will be owned by the psymbol_functions object. This patch is a step toward this goal. The storage is already managed as a shared_ptr, to enable cross-objfile sharing, so this adds a reference from the psymbol_functions, and changes some code in psymtab.c to use this reference instead. gdb/ChangeLog 2021-03-20 Tom Tromey <tom@tromey.com> * dwarf2/read.c (dwarf2_build_psymtabs): Call set_partial_symtabs. * symfile.c (syms_from_objfile_1, reread_symbols): Update. * psymtab.h (make_psymbol_functions): Add partial_symtabs parameter. * psymtab.c (find_pc_sect_psymtab): Add partial_symtabs parameter.
