The argument ARGS of gdb_init is passed from dejagnu is a string, the
test file name. In dejagnu/runtest.exp:
proc runtest { test_file_name } {
....
....
if [info exists tool] {
if { [info procs "${tool}_init"] != "" } {
${tool}_init $test_file_name;
}
}
....
}
but inn default_gdb_init (callee of gdb_init), we have
set gdb_test_file_name [file rootname [file tail [lindex $args 0]]]
In tcl, all actual arguments are combined to a list and assigned to
args. This code here isn't wrong, but unnecessary, because its caller
(proc runtest) only passes one string to it, and IMO, we don't need
such tricky tcl "args".
I doubt that "[lindex $args 0]" is to be backward compatible with old
dejagnu, but dejagnu-1.4 release started to pass $test_file_name to
${too}_init, as I showed above. dejagnu-1.4 was released in 2001, and
it should be old enough. I also tried to check whether gdb testusite
works with dejagnu-1.3 or not, but failed to build dejagnu-1.3 on my
machine. Supposing GDB testsuite requires at least dejagnu-1.4, this
change should be safe.
This patch is update default_gdb_init to treat ARGS as a string instead
of a list. Then, 'args' sounds like a list, and this patch also renames
it by 'test_file_name', to align with dejagnu.
gdb/testsuite:

* lib/gdb.exp (default_gdb_init): Rename argument 'args' by
'test_file_name'. Treat args as a string instead of a list.
(gdb_init): Rename argument 'args' by 'test_file_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.
