This patch removes the "readin" and "compunit_symtab" members from partial_symtab, replacing them with methods. Then it introduces a new "standard_psymtab" class, which restores these members; and changes the symbol readers to use this intermediate class as the base class of their partial symtab subclasses. The reason for this is to make it possible for a symbol reader to implement an alternate mapping between partial and full symbol tables. This is important in order to be able to share psymtabs across objfiles -- whether a psymtab has been "readin" is objfile-dependent, as are the pointers to the full symbol tables. gdb/ChangeLog 2020-01-26 Tom Tromey <tom@tromey.com> * 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) (partial_symtab::read_dependencies, maintenance_info_psymtabs) (maintenance_check_psymtabs): Use new methods. * psympriv.h (struct partial_symtab) <readin_p, get_compunit_symtab>: New methods. <readin, compunit_symtab>: Remove members. (struct standard_psymtab): New. (struct legacy_psymtab): Derive from standard_psymtab. * dwarf2read.h (struct dwarf2_psymtab): Derive from standard_psymtab. * ctfread.c (struct ctf_psymtab): Derive from standard_psymtab.

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
