In my remote cross testing (x86_64 host and aarch64 target), the test gdb.base/sizeof.exp is skipped because gdb,noinferiorio is defined in my gdbserver board file. Tests are skipped because the test checks the expected value from the program's output, but I don't see why must do it this way. With my patch applied, we can save the result in variable in the program, and check the variable then. Then, the test doesn't rely on inferiorio. gdb/testsuite: 2015-12-03 Yao Qi <yao.qi@linaro.org> * gdb.base/sizeof.c: Don't include stdio.h and ../lib/unbuffer_output.c. (main): New variable 'size' and 'value'. Remove printf and gdb_unbuffer_output. Assign return value to size and value. * gdb.base/sizeof.exp: Remove the checking to gdb,noinferiorio at the beginning. (check_sizeof): Check the result by printing variable 'size'. (check_valueof): Check the result by printing variable 'value'.
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.
