Building on the previous commits, this commit goes through the various gdbarch_register_name methods and removes all the remaining 'return NULL' cases, I claim that these either couldn't be hit, or should be returning the empty string. In all cases the return of NULL was used if the register number being passed to gdbarch_register_name was "invalid", i.e. negative, or greater than the total number of declared registers. I don't believe either of these cases can occur, and the previous commit asserts that this is the case. As a result we can simplify the code by removing these checks. In many cases, where the register names are held in an array, I was able to add a static assert that the array contains the correct number of strings, after that, a direct access into the array is fine. I don't have any means of testing these changes.
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.
