In the failure seen by Philippe here: https://inbox.sourceware.org/gdb-patches/20221120173024.3647464-1-philippe.waroquiers@skynet.be/ ... the testsuite only outputs PASSes, and an ERROR, resulting from an uncaught exception. This is a bit sneaky, because ERRORs are not reported in the test summary. In certain circumstances, it can be easy to miss. Normally, gdb_test_multiple outputs an UNRESOLVED when GDB crashes. But this is only if it manages to send the command, and it's that command that crashes GDB. Here, the ERROR is due to the fact that GDB had already crashed by the time we entered gdb_test_multiple and tried to send a command. GDB was crashed by the previous "file" command, sent by gdb_unload. Because gdb_unload uses bare expect, it didn't record a test failure when crashing GDB (this will be addressed separately). In this patch, I propose to make gdb_test_multiple call unresolved directly and return -1 send_gdb fails. This way, if GDB is already crashed by the time we enter gdb_test_multiple, it will leave a trace in the test results in the form of an UNRESOLVED. It will also spare us the not-so-useful-in-my-opinion TCL backtrace. Before, it looks like: ERROR: Couldn't send python print(objfile.filename) to GDB. ERROR: : spawn id exp9 not open while executing "expect { -i exp9 -timeout 10 -re ".*A problem internal to GDB has been detected" { fail "$message (GDB internal error)" gdb_internal_error..." ("uplevel" body line 1) invoked from within "uplevel $body" NONE : spawn id exp9 not open And after: Couldn't send python print(objfile.filename) to GDB. UNRESOLVED: gdb.python/py-objfile.exp: objfile.filename after objfile is unloaded Change-Id: I72af8dc0d687826fc3f76911c27a9e5f91b677ba Approved-By: Tom de Vries <tdevries@suse.de> |

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.
