After the previous commit, this commit sets out to formalise the API
for gdbarch_register_name. Not every architecture is actually in
compliance with the API I set out here, but I believe that most are.
I think architectures that don't comply with the API laid out here
will fail the gdb.base/completion.exp test.
The claims in the comment are I feel, best demonstrated with the
asserts in this code:
const char *
gdbarch_register_name (struct gdbarch *gdbarch, int regnr)
{
gdb_assert (regnr >= 0);
gdb_assert (regnr < gdbarch_num_cooked_regs (gdbarch));
const char *name = gdbarch->register_name (gdbarch, regnr);
gdb_assert (name != nullptr);
return name;
}
Like I said, I don't believe every architecture follows these rules
right now, which is why I'm not actually adding any asserts. Instead,
this commit adds a comment to gdbarch_register_name, this comment is
where I'd like to get to, rather than where we are right now.
Subsequent commits will fix all targets to be in compliance with this
comment, and will even add the asserts shown above to
gdbarch_register_name.
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.
