Use the construct_inferior_arguments function instead of
stringify_argv to construct a string from the program
arguments in those places where that one is then passed
to fork_inferior (linux-low, lyn-low), since
construct_inferior_arguments properly takes care of
special characters, while stringify_argv does not.
Using construct_inferior_arguments seems "natural", since its
documentation also mentions that it "does the
same shell processing as fork_inferior".
Since construct_inferior_args has been extended to do
proper quoting for Windows shells in commit
5d60742e2d
("Fix quoting of special characters for the MinGW build.",
2012-06-12), use it for the Windows case as well.
(I could not test that case myself, though.)
Adapt handling of empty args in function 'handle_v_run'
in gdbserver/server.cc to just insert an empty string
for an empty arg, since that one is now properly handled
in 'construct_inferior_arguments' already (and inserting
a "''" string in 'handle_v_run' would otherwise
cause that one to be treated as a string literally
containing two quote characters, which
'construct_inferior_args' would preserve by adding
extra escaping).
This makes gdbserver properly handle program args containing special
characters (like spaces), e.g. (example from PR25893)
$ gdbserver localhost:50505 myprogram "hello world"
now properly handles "hello world" as a single arg, not two separate
ones ("hello", "world").
gdbserver/ChangeLog:
PR gdbserver/25893
* linux-low.cc (linux_process_target::create_inferior),
lynx-low.cc (lynx_process_target::create_inferior),
win32-low.cc (win32_process_target::create_inferior): Use
construct_inferior_arguments instead of stringify_argv
to get string representation which properly escapes
special characters.
* server.cc (handle_v_run): Just pass empty program arg
as such, since any further processing is now handled via
construct_inferior_arguments.

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.
