I am confused by the noargs checking at each proc in commands.exp,
if [target_info exists noargs] {
verbose "Skipping progvar_simple_while_test because of noargs."
return
}
gdb_test_no_output "set args 5" "set args in progvar_simple_while_test"
if { ![runto factorial] } then { gdb_suppress_tests }
# Don't depend upon argument passing, since most simulators don't
# currently support it. Bash value variable to be what we want.
gdb_test "p value=5" ".*" "set value to 5 in progvar_simple_if_test #2"
They are conflicting to me. If the argument passing can't be done on
the target, we skip this test, why do we still have to set value below?
On the other hand, the test case is compiled with -DFAKEARGV, it doesn't
get anything from argv[1], why do we need to skip it if noargs is true?
I don't find any useful clues from the git log, as the code is quite
old, predating import to sourceware cvs. However, I find something
useful from the ChangeLog.

.....
* gdb.base/commands.exp: Protect tests which need arguments with
$noargs conditionals.
Mon Apr 21 13:38:58 1997 Fred Fish <fnf@cygnus.com>
* gdb.base/run.c: Use FAKEARGV to build test executable that
does not require a command line arg, since most simulators
don't currently support passing such an arg into the simulated
program.
* gdb.base/commands.exp: Change tests to insert the proper
value as the arg to the first recursive factorial call. Change
compilation line to define FAKEARGV at compile time.
Jeff added noargs checking as argument is passed to the inferior. Then,
I presume Fred wanted to run this test on simulators which don't support
argument passing, and change the code not get input from argv. (I guess)
noargs wasn't set in simulator board files at that moment.
Since Fred changed test to set input by gdb, instead of getting input
from argv, the test should be able to run on target doesn't support
argument passing, such as simulator and gdbserver.
This patch is to remove these checks to noargs and "set args". I run
commands.exp with these board files, and no fail is found
- unix and native-gdbserver
- arm-none-eabi with qemu
- gdbserver on arm-linux-gnueabi with qemu

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.
