Simon Marchi 5a9dcda14c C++ify xml-syscall.c
This patch C++ifies the structures in xml-syscall.c, by using
std::vector instead of VEC, and std::string instead of char*.
Using a unique_ptr in syscall_parse_xml allows to remove a cleanup.

Something that seems strange with the existing code, if you look at
syscalls_info_free_syscalls_desc and
syscalls_info_free_syscall_group_desc, they free the structure elements
(the strings and vectors), but they don't free the syscall_desc and
syscall_group_desc structure themselves.  I don't see anything freeing
those currently.  Any idea why?  According to the comment above
syscalls_info_free_syscall_group_desc, it kinda looks like it's on
purpose.  With this patch, those structures are deleted when the vector
that contains them gets deleted.

The only time I'm aware a syscalls_info structure gets deleted is in the
case the data directory changes during runtime, in init_syscalls_info.
If tried that use case (including under valgrind):

 (gdb) catch syscall
 (gdb) set data-directory another-data-directory
 (gdb) catch syscall

I confirmed that the syscalls_info structure got deleted and recreated,
and everything seemed fine.

Regtested on the buildbot.

		   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.
