GDB that can debug Mach-Os on Linux
673dc4a054
I see the following two fails on arm-none-eabi target, because argv[0] isn't available. print argv[0]^M $1 = 0x1f78 "/dev/null"^M (gdb) FAIL: gdb.base/argv0-symlink.exp: kept file symbolic link name print argv[0]^M $1 = 0x1f78 "/dev/null"^M (gdb) FAIL: gdb.base/argv0-symlink.exp: kept directory symbolic link name My first thought is to check [target_info exists noargs], and skip the test if it returns true. However, noargs is set in gdbserver board files, so argv0-symlink.exp will be skipped on gdbserver board file. The change is too aggressive. When the program is running with gdbserver, argv[1] to argv[N] aren't available, but argv[0] is. Fortunately, argv0-symlink.exp only requires argv[0]. argv0-symlink.exp can be run with gdbserver board file, as what we do now. What we need to check is whether argv[0] is available, so I add a new proc gdb_has_argv0 to do so by starting a program, and check argc/argv[0] to see whether argv[0] is available. Dan fixed the similar problem by checking noargs, which is too strong. https://sourceware.org/ml/gdb-patches/2010-02/msg00398.html as a result, the test is skipped on gdbserver. This patch fixed it too. gdb/testsuite: 2014-10-18 Yao Qi <yao@codesourcery.com> * gdb.base/argv0-symlink.exp: Check argv[0] value if gdb_has_argv0 return true. * gdb.guile/scm-value.exp (test_value_in_inferior): Don't check [target_info exists noargs], check [gdb_has_argv0] instead. * gdb.python/py-value.exp (test_value_in_inferior): Likewise. * lib/gdb.exp (gdb_has_argv0, gdb_has_argv0_1): New procedures. |

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.
