Max Filippov cd665a945e gas: xtensa: limit size of auto litpools
Literal movement code may grow auto litpool so big that it won't be
possible to jump around it. Limit the size of auto litpools by 1/2 of
the jump range.

gas/
2018-02-20  Max Filippov  <jcmvbkbc@gmail.com>

	* config/tc-xtensa.c (struct litpool_frag): Add new field
	literal_count.
	(MAX_AUTO_POOL_LITERALS, MAX_EXPLICIT_POOL_LITERALS)
	(MAX_POOL_LITERALS): New macro definitions.
	(auto_litpool_limit): Initialize to 0.
	(md_parse_option): Set auto_litpool_limit in the presence of
	--auto-litpools option.
	(xtensa_maybe_create_literal_pool_frag): Zero-initialize
	literal_count field.
	(xg_find_litpool): New function. Make sure that found literal
	pool size is within the limit.
	(xtensa_move_literals): Extract literal pool search code into
	the new function.
	* testsuite/gas/xtensa/all.exp: Add auto-litpools-2 test.
	* testsuite/gas/xtensa/auto-litpools-2.d: New file.
	* testsuite/gas/xtensa/auto-litpools-2.s: New file.
	* testsuite/gas/xtensa/auto-litpools.d: Fix up changed
	addresses.
	* testsuite/gas/xtensa/auto-litpools.s: Change literal value so
	that objdump doesn't get out of sync.

		   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.
