There exist expected failures in the pass-by-ref.exp and pass-by-ref-2.exp tests based on the GCC and Clang version. * GCC version <= 6 and Clang do not emit DW_AT_deleted and DW_AT_defaulted. * Clang version >= 7 emits DW_AT_calling_convention, which helps the debugger make the right calling convention decision in some cases despite lacking the 'defaulted' and 'deleted' attributes. Mark the related tests as XFAIL based on the compiler version. Tested on X86_64 using GCC 5.5.0, 6.5.0, 7.4.0, 8.3.0, 9.2.1; and Clang 5.0.1, 6.0.0, 7.0.0, 8.0.0, 9.0.1, 10.0.0. gdb/testsuite/ChangeLog: 2020-01-29 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * gdb.cp/pass-by-ref-2.exp: Mark some tests as XFAIL based on the GCC/Clang version. * gdb.cp/pass-by-ref.exp: Ditto.

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.
