Pedro Alves 51abb42130 Kill init_sal
Instead, make symtab_and_line initialize its members itself.  Many
symtab_and_line declarations are moved to where the object is
initialized at the same time both for clarity and to avoid double
initialization.  A few functions, like e.g., find_frame_sal are
adjusted to return the sal using normal function return instead of an
output parameter likewise to avoid having to default-construct a sal
and then immediately have the object overwritten.

	* stack.c (set_current_sal_from_frame): Adjust.
	(print_frame_info): Adjust.
	(get_last_displayed_sal): Return the sal via function return
	instead of via output parameter.  Simplify.
	(frame_info): Adjust.
	* stack.h (get_last_displayed_sal): Return the sal via function
	return instead of via output parameter.
	* symtab.c (init_sal): Delete.
	(find_pc_sect_line): Remove init_sal references.  Move
	declarations closer to initializations.
	(find_function_start_sal): Remove init_sal references.  Move
	declarations closer to initializations.
	* symtab.h (struct symtab_and_line): In-class initialize all
	fields.
	* tracepoint.c (set_traceframe_context)
	(print_one_static_tracepoint_marker): Remove init_sal references.
	Move declarations closer to initializations.
	* tui/tui-disasm.c (tui_show_disassem_and_update_source): Adjust.
	* tui/tui-stack.c (tui_show_frame_info): Adjust.  Move
	declarations closer to initializations.

		   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.
