Pedro Alves 06871ae840 Make "list ambiguous" show symbol names too
Currently, with an ambiguous "list first,last", we get:

  (gdb) list bar,main
  Specified first line 'bar' is ambiguous:
  file: "src/gdb/testsuite/gdb.cp/overload.cc", line number: 97
  file: "src/gdb/testsuite/gdb.cp/overload.cc", line number: 98

This commit makes gdb's output above a bit clearer by printing the
symbol name as well:

  (gdb) list bar,main
  Specified first line 'bar' is ambiguous:
  file: "src/gdb/testsuite/gdb.cp/overload.cc", line number: 97, symbol: "bar(A)"
  file: "src/gdb/testsuite/gdb.cp/overload.cc", line number: 98, symbol: "bar(B)"

And while at it, makes gdb print the symbol name when actually listing
multiple locations too.  I.e., before (with "set listsize 2"):

  (gdb) list bar
  file: "src/gdb/testsuite/gdb.cp/overload.cc", line number: 97
  96
  97      int bar (A) { return 11; }
  file: "src/gdb/testsuite/gdb.cp/overload.cc", line number: 98
  97      int bar (A) { return 11; }
  98      int bar (B) { return 22; }

After:

  (gdb) list bar
  file: "src/gdb/testsuite/gdb.cp/overload.cc", line number: 97, symbol: "bar(A)"
  96
  97      int bar (A) { return 11; }
  file: "src/gdb/testsuite/gdb.cp/overload.cc", line number: 98, symbol: "bar(B)"
  97      int bar (A) { return 11; }
  98      int bar (B) { return 22; }

Currently, the result of decoding a linespec loses information about
the original symbol that was found.  All we end up with is an address.
This makes it difficult to find the original symbol again to get at
its print name.  Fix that by storing a pointer to the symbol in the
sal.  We already store the symtab and obj_section, so it feels like a
natural progression to me.  This avoids having to do any extra symbol
lookup too.

gdb/ChangeLog:
2017-09-20  Pedro Alves  <palves@redhat.com>

	* cli/cli-cmds.c (list_command): Use print_sal_location.
	(print_sal_location): New function.
	(ambiguous_line_spec): Use print_sal_location.
	* linespec.c (symbol_to_sal): Record the symbol in the sal.
	* symtab.c (find_function_start_sal): Likewise.
	* symtab.h (symtab_and_line::symbol): New field.

gdb/testsuite/ChangeLog:
2017-09-20  Pedro Alves  <palves@redhat.com>

	* gdb.base/list-ambiguous.exp (test_list_ambiguous_symbol): Expect
	symbol names in gdb's output.
	* gdb.cp/overload.exp ("list all overloads"): Likewise.

		   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.
