This gets rid of the core_ops global, and replaces it with heap-allocated core_target instances. In practice, there will only be one such instance, though that will change further ahead as more pieces of multi-target support are merged. Notice that this replaces one heap-allocated object for another, the number of allocations is the same. Specifically, currently we heap-allocate the 'core_data' object, which holds the core's section table. With this patch, that object is made a field of the core_target class, and no longer allocated separately. Note that this bit: - /* Looks semi-reasonable. Toss the old core file and work on the - new. */ - - unpush_target (&core_ops); does not need a replacement, because by the time we get here, the target_preopen call at the top of core_target_open has already unpushed any previous target. gdb/ChangeLog: 2018-05-11 Pedro Alves <palves@redhat.com> * corelow.c (core_target) <core_target>: No longer inline. Initialize m_core_gdbarch, m_core_vec and build the section table here. <~core_target>: New. <core_gdbarch, get_core_register_section>: New methods. <m_core_section_table, m_core_vec, m_core_gdbarch>: New fields, factored out from ... <core_data, core_vec, core_gdbarch>: ... these deleted globals. (core_ops): Delete. (sniff_core_bfd): Add gdbarch parameter. (core_close): Delete, merged into ... (core_target::close): ... here. Delete self. (core_close_cleanup): Delete. (core_target_open): Allocate a core_target on the heap. Use a unique_ptr instead of a cleanup. Bits moved into the core_target ctor. Adjust to use core_target methods instead of globals. (get_core_register_section): Rename to ... (core_target::get_core_register_section): ... this and adjust. (struct get_core_registers_cb_data): New. (get_core_registers_cb): Use it. Use bool. (core_target::fetch_registers, core_target::files_info) (core_target::xfer_partial, core_target::read_description) (core_target::pid_to, core_target::thread_name): Adjust to reference class fields instead of globals. * target.h (struct target_ops_deleter, target_ops_up): New.
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.
