This introduces a new partial_symtab::read_symtab method, and updates the symbol readers to subclass partial_symtab and implement this method. The old read_symtab and read_symtab_private members are removed. In practice, only DWARF and CTF are truly updated to take advantage of the new setup. The other symbol readers are less actively maintained, and so this patch also introduces a "legacy_psymtab", which essentially works the same way as the old partial_symtab. (Note that, without more knowledge of the interaction between these symbol readers, fixing this to remove the new (small) overhead is not trivial, because these readers copy the read_symtab pointer between partial symtabs.) gdb/ChangeLog 2020-01-26 Tom Tromey <tom@tromey.com> * xcoffread.c (this_symtab_psymtab, read_xcoff_symtab) (xcoff_psymtab_to_symtab_1, xcoff_read_symtab) (xcoff_start_psymtab, xcoff_end_psymtab, scan_xcoff_symtab): Use legacy_symtab. * stabsread.h (dbx_end_psymtab): Use legacy_symtab. * psymtab.c (psymtab_to_symtab): Call method.

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.
