I noticed an oddity in skip_ctf_tests -- for me it ends up caching the string "!0", because it ends with 'return ![...]'. In Tcl, this is just string concatenation. The result works because the users of this function have unbraced if conditions, like: if [skip_ctf_tests] { ... which works because "if" re-parses the returned string as an expression, and evaluates that. There's only a latent bug here, but this is also un-idiomatic, so I am checking in this patch to fix it. This way, if someone in the future uses a braced condition (which is what I normally recommend), it will continue to work. gdb/testsuite/ChangeLog 2021-02-26 Tom Tromey <tom@tromey.com> * lib/gdb.exp (skip_ctf_tests): Use expr on result.
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.
