The test disassembles function foo and searches for the line "End of assembler dump" to determing the last address in the function. The assumption is the last instruction will be given right before the line "End of assembler dump". This assumption fails on PowerPC. The PowerPC disassembly of the function foo looks like: Dump of assembler code for function foo: # => 0x00000000100006dc <+0>: std r31,-8(r1) # 0x00000000100006e0 <+4>: stdu r1,-48(r1) # 0x00000000100006e4 <+8>: mr r31,r1 # 0x00000000100006e8 <+12>: nop # 0x00000000100006ec <+16>: addi r1,r31,48 # 0x00000000100006f0 <+20>: ld r31,-8(r1) # 0x00000000100006f4 <+24>: blr # 0x00000000100006f8 <+28>: .long 0x0 # 0x00000000100006fc <+32>: .long 0x0 # 0x0000000010000700 <+36>: .long 0x1000180 # End of assembler dump. The blr instruction is the last instruction in function foo. The lines with .long following the blr instruction need to be ignored. This patch adds a new condition to the gdb_test_multiple "disassemble foo" test to ignore the lines with the .long. The patch has been tested on PowerPC and Intel X86-64.
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.
