This commit builds on the previous series of commits to share the target description caching code between GDB and gdbserver for x86/Linux targets. The objective of this commit is to move the four functions (2 each of) i386_linux_read_description and amd64_linux_read_description into gdb/nat/x86-linux-tdesc.c and combine them so we have just a single copy of each. Then both GDB and gdbserver will link against these shared functions. It is worth reading the description of the previous commit to see why this merging is not as simple as it seems: on the gdbserver side we actually have two users of these functions, gdbserver itself, and the in process agent (IPA). However, the previous commit streamlined the gdbserver code, and so now it is simple to move the two functions along with all their support functions from the gdbserver directory into the gdb/nat/ directory, and then GDB is fine to call these functions. One small curiosity with this patch is the function x86_linux_post_init_tdesc. On the gdbserver side the two functions amd64_linux_read_description and i386_linux_read_description have some functionality that is not present on the GDB side, that is some additional configuration that is performed as each target description is created to setup the expedited registers. To support this I've added the function x86_linux_post_init_tdesc. This function is called from the two *_linux_read_description functions, but is implemented separately for GDB and gdbserver. This does mean adding back some non-shared code when this whole series has been about sharing code, but now the only non-shared bit is the single line that is actually different between GDB and gdbserver, all the rest, which is identical, is now shared. I did need to add a new rule to the gdbserver Makefile, this is to allow the nat/x86-linux-tdesc.c file to be compiled for the IPA. Approved-By: John Baldwin <jhb@FreeBSD.org> |

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.
