Kevin Buettner e94802301b Disassemble blocks with non-contiguous ranges
This patch adds support for disassembly of blocks with non-contiguous
ranges.  These blocks are printed as follows:

(gdb) disassemble foo
Dump of assembler code for function foo:
Address range 0x401136 to 0x401151:
   0x0000000000401136 <+0>:     push   %rbp
   0x0000000000401137 <+1>:     mov    %rsp,%rbp
   0x000000000040113a <+4>:     callq  0x401134 <bar>
   0x000000000040113f <+9>:     mov    0x2eef(%rip),%eax        # 0x404034 <e>
   0x0000000000401145 <+15>:    test   %eax,%eax
   0x0000000000401147 <+17>:    je     0x40114e <foo+24>
   0x0000000000401149 <+19>:    callq  0x401128 <foo+4294967282>
   0x000000000040114e <+24>:    nop
   0x000000000040114f <+25>:    pop    %rbp
   0x0000000000401150 <+26>:    retq
Address range 0x401128 to 0x401134:
   0x0000000000401128 <+-14>:   push   %rbp
   0x0000000000401129 <+-13>:   mov    %rsp,%rbp
   0x000000000040112c <+-10>:   callq  0x401126 <baz>
   0x0000000000401131 <+-5>:    nop
   0x0000000000401132 <+-4>:    pop    %rbp
   0x0000000000401133 <+-3>:    retq
End of assembler dump.

This is an actual dump from the test case that I constructed for
this work.  The ranges are printed in the order encountered in the
debug info. For the above example, note that the second range occupies
lower addresses than the first range.

Functions with contiguous ranges are still printed as follows:

(gdb) disassemble main
Dump of assembler code for function main:
   0x0000000000401151 <+0>:     push   %rbp
   0x0000000000401152 <+1>:     mov    %rsp,%rbp
   0x0000000000401155 <+4>:     callq  0x401136 <foo>
   0x000000000040115a <+9>:     mov    $0x0,%eax
   0x000000000040115f <+14>:    pop    %rbp
   0x0000000000401160 <+15>:    retq
End of assembler dump.

README

		   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.
