Jan Beulich 2ee1792bec gas: further adjust file/line handling for .irp and alike
Commit 7992631e8c0b ("gas/Dwarf: improve debug info generation from .irp
and alike blocks"), while dealing okay with actual assembly source files
not using .file/.line and alike outside but not inside of .irp et al,
has undue effects when the logical file/line pair was already
overridden: Line numbers would continuously increment upon every
iteration, thus potentially getting far off. Furthermore it left it to
the user to actually insert .file/.line inside such constructs. Note
though that before aforementioned change things weren't pretty either:
Diagnostics (and debug info) would be associated with the directive
terminating the iteration construct, rather than with the actual lines.

Handle this automatically by simply latching the present line and then
re-instating coordinates first thing on every iteration; note that the
file can't change from what was previously pushed on the scrubber's
state stack, and hence can be taken from there by using a new flavor of
.linefile (which is far better memory-footprint-wise than recording the
full path in the inserted directive). (This then leaves undisturbed any
file/line control occurring in the body of the construct, as these will
only be seen and processed afterwards.)

		   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.
