The gdbsupport directory contains a helper class print_xml_feature that is shared between gdb and gdbserver. This class is used for printing an XML representation of a target_desc object. Currently this class doesn't have the ability to print the <compatible> entities that can appear within a target description, I guess no targets have needed that functionality yet. The print_xml_feature classes API is based around operating on the target_desc class, however, the sharing between gdb and gdbserver is purely textural, we rely on their being a class called target_desc in both gdb and gdbserver, but there is no shared implementation. We then have a set of functions declared that operate on an object of type target_desc, and again these functions have completely separate implementations. Currently then the gdb version of target_desc contains a vector of bfd_arch_info pointers which represents the compatible entries from a target description. The gdbserver version of target_desc has no such information. Further, the gdbserver code doesn't seem to include the bfd headers, and so doesn't know about the bfd types. I was reluctant to include the bfd headers into gdbserver just so I can reference the compatible information, which isn't (currently) even needed in gdbserver. So, the approach I take in this patch is to wrap the compatible information into a new helper class. This class is declared in the gdbsupport library, but implemented separately in both gdb and gdbserver. In gdbserver the class is empty. The compatible information within the gdbserver is an empty list, of empty classes. In gdb the class contains a pointer to the bfd_arch_info object. With this in place we can now add support to print_xml_feature for printing the compatible information if it is present. In the gdbserver code this will never happen, as the gdbserver never has any compatible information. But in gdb, this code will trigger when appropriate. gdb/ChangeLog: * target-descriptions.c (class tdesc_compatible_info): New class. (struct target_desc): Change type of compatible vector. (tdesc_compatible_p): Update for change in type of target_desc::compatible. (tdesc_compatible_info_list): New function. (tdesc_compatible_info_arch_name): New function. (tdesc_add_compatible): Update for change in type of target_desc::compatible. (print_c_tdesc::visit_pre): Likewise. gdbserver/ChangeLog: * tdesc.cc (struct tdesc_compatible_info): New struct. (tdesc_compatible_info_list): New function. (tdesc_compatible_info_arch_name): New function. gdbsupport/ChangeLog: * tdesc.cc (print_xml_feature::visit_pre): Print compatible information. * tdesc.h (struct tdesc_compatible_info): Declare new struct. (tdesc_compatible_info_up): New typedef. (tdesc_compatible_info_list): Declare new function. (tdesc_compatible_info_arch_name): Declare new function. |

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.
