Remove the use of xmalloc (and the arbitrary allocation size) in format_pieces. This turned out a bit more involved than expected, but not too bad. format_pieces::m_storage is a buffer with multiple concatenated null-terminated strings, referenced by format_piece::string. Change this to an std::string, while keeping its purpose (use the std::string as a buffer with embedded null characters). However, because the std::string's internal buffer can be reallocated as it grows, and I do not want to hardcode a big reserved size like we have now, it's not possible to store the direct pointer to the string in format_piece::string. Those pointers would become stale as the buffer gets reallocated. Therefore, change format_piece to hold an index into the storage instead. Add format_pieces::piece_str for the callers to be able to access the piece's string. This requires changing the few callers, but in a trivial way. The selftest also needs to be updated. I want to keep the test cases as-is, where the expected pieces contain the expected string, and not hard-code an expected index. To achieve this, add the expected_format_piece structure. Note that the previous format_piece::operator== didn't compare the n_int_args fields, while the test provides expected values for that field. I guess that was a mistake. The new code checks it, and the test still passes. Change-Id: I80630ff60e01c8caaa800ae22f69a9a7660bc9e9 Reviewed-By: Keith Seitz <keiths@redhat.com>

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, and so on. 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.
