When testing using reverse-stepi to fully step through a function, the code checks for an infinite loop by seeing if we land on the line that contains the return statement multiple times. This assumption only works if there is only one instruction associated with that line, which is how GCC handles line information, but other compilers may handle it differently. Clang-15, for instance, associates 6. Because of this, the inferior used to get seriously out of sync with the test expectations, and result in 13 spurious failures. The same issue occurs with gdb.reverse/step-precsave.exp. This commit changes the test so that we check for PC instead of line number. The test still only happens when the same line is detected, to simplify the resulting log. With this change, no new failures are emitted when using clang. Approved-By: Tom Tromey <tom@tromey.com>
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.
