On openSUSE Leap 15.2 aarch64 I ran into: ... FAIL: gdb.tui/basic.exp: check main is where we expect on the screen ... while this is passing on x86_64. On x86_64-linux we have at the initial screen dump for "list -q main": ... 0 +-/home/vries/gdb_versions/devel/src/gdb/testsuite/gdb.tui/tui-layout.c--+ 1 | 15 You should have received a copy of the GNU General Public | 2 | 16 along with this program. If not, see <http://www.gnu.org/| 3 | 17 | 4 | 18 int | 5 | 19 main () | 6 | 20 { | 7 | 21 return 0; | 8 | 22 } | 9 | 23 | ... but on aarch64: ... 0 +-/home/tdevries/gdb/src/gdb/testsuite/gdb.tui/tui-layout.c--------------+ 1 | 16 along with this program. If not, see <http://www.gnu.org/| 2 | 17 | 3 | 18 int | 4 | 19 main () | 5 | 20 { | 6 | 21 return 0; | 7 | 22 } | 8 | 23 | 9 | 24 | ... The cause of the diffferent placement is that we have as line number for main on x86_64: ... $ gdb -q -batch outputs/gdb.tui/basic/basic -ex "info line main" Line 20 of "tui-layout.c" starts at address 0x4004a7 <main> \ and ends at 0x4004ab <main+4>. ... and on aarch64 instead: ... $ gdb -q -batch outputs/gdb.tui/basic/basic -ex "info line main" Line 21 of "tui-layout.c" starts at address 0x4005f4 <main> \ and ends at 0x4005f8 <main+4>. ... Fix this by using a new source file main-one-line.c, that implements the entire main function on a single line, in order to force the compiler to use that line number. Also try to do less hard-coding in the test-case. Tested on x86_64-linux and aarch64-linux. |

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.
