Disable the Traceback Table generation on PowerPC for this test. The Traceback Table consists of a series of bit fields to indicate things like the Traceback Table version, language, and specific information about the function. The Traceback Table is generated following the end of the code for every function by default. The Traceback Table is defined in the PowerPC ELF ABI and is intended to support debuggers and exception handlers. The Traceback Table is displayed in the disassembly of functions by default and is part of the function length. The table is typically interpreted by the disassembler as data represented by .long xxx entries. Generation of the Traceback Table is disabled in this test using the PowerPC specific gcc compiler option -mtraceback=no, the xlc option additional_flags-qtable=none and the clang optons -mllvm -xcoff-traceback-table=false. Disabling the Traceback Table generation in this test results in the gdb_test_multiple statement correctly locating the address of the bclr instruction before the statement "End of assembler dump." in the disassembly output.
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.
