[RFA 08/15] Remove readin and compunit_symtab fields from psymtab
Tom Tromey
tom@tromey.com
Thu May 10 22:25:00 GMT 2018
In order to move psymtabs off of the objfile obstack, there must be no
backlinks from the psymtab (or associated objects) to anything
allocated on the objfile obstack.
This patch removes the readin and compunit_symtab fields from psymtab
to help achieve this goal, replacing them with per-objfile maps
indicating which psymtabs have been read in. This split will allow
for psymtab reuse across objfiles in the future.
2018-05-10 Tom Tromey <tom@tromey.com>
* symfile.c (reread_symbols): Clear psymtab_map.
* xcoffread.c (read_xcoff_symtab, xcoff_psymtab_to_symtab_1)
(xcoff_read_symtab): Update.
* psymtab.h (associate_psymtab_with_symtab, psymtab_read_in_p)
(get_psymtab_compunit): Declare.
* psymtab.c (partial_map_expand_apply)
(psym_find_pc_sect_compunit_symtab, psym_lookup_symbol)
(psymtab_to_symtab, psym_find_last_source_symtab, dump_psymtab)
(psym_print_stats, psym_expand_symtabs_for_function)
(psym_map_symbol_filenames, psym_map_matching_symbols)
(psym_expand_symtabs_matching, allocate_psymtab): Update.
(associate_psymtab_with_symtab, psymtab_read_in_p)
(get_psymtab_compunit): New functions.
(maintenance_info_psymtabs, maintenance_check_psymtabs): Update.
* psympriv.h (struct partial_symtab) <readin, compunit_symtab>:
Remove.
* objfiles.h (objfile::psymtab_map): New member.
* mdebugread.c (psymtab_to_symtab_1): Update.
* dwarf2read.c (dw2_do_instantiate_symtab, dwarf2_read_symtab)
(process_queue): Update.
(psymtab_to_symtab_1): Add 'objfile' parameter.
(get_compunit_symtab, process_full_comp_unit)
