Function Create_large returns a large data structure. On PowerPC, register r3 contains the address of where the data structure to be returned is to be stored. However, on exit the ABI does not guarantee that r3 has not been changed. The GDB finish command prints the return value of the function at the end of the function. GDB needs to use the DW_TAG_call_site information to determine the value of r3 on entry to the function to correctly print the return value at the end of the function. The test must be compiled with -fvar-tracking for the DW_TAG_call_site information to be included in the executable file. This patch adds the -fvar-tracking option to the compile line if the option is supported. The patch fixes the one regression error for the test on PowerPC. The patch has been tested on Power 10 and X86-64 with no regressions.
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.
