Extend testcases for GDB's infcall of call-by-value functions that take aggregate values as parameters. In particular, existing test has been substantially extended with class definitions whose definitions of copy constructor, destructor, and move constructor functions are a combination of (1) explicitly defined by the user, (2) defaulted inside the class declaration, (3) defaulted outside the class declaration, (4) deleted (5) not defined in the source. For each combination, a small and a large class is generated as well as a derived class and a container class. Additionally, the following manually-written cases are provided: - a dynamic class (i.e. class with a virtual method) - classes that contain an array field - a class whose copy ctor is inlined - a class whose destructor is deleted - classes with multiple copy and/or move ctors Test cases check whether GDB makes the right decision to pass an object by value or implicitly by reference, whether really a copy of the argument is passed, and whether the copy constructor and destructor of the clone of the argument are invoked properly. The input program pass-by-ref.cc is generated in the test's output directory. The input program pass-by-ref-2.cc is manually-written. Tests have been verified on the X86_64 architecture with GCC 7.4.0, 8.2.0, and 9.2.1. gdb/testsuite/ChangeLog: 2019-12-20 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * gdb.cp/pass-by-ref.cc: Delete. Generated in the output directory instead. * gdb.cp/pass-by-ref.exp: Extend with more cases. * gdb.cp/pass-by-ref-2.cc: New file. * gdb.cp/pass-by-ref-2.exp: New file.

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.
