Jose E. Marchesi 8b8c7c9f49 gas: sparc: fix collision of registers and pseudo-ops.
The current sparc assembler breaks when the name of an ancillary-state
register, privileged register or hyperprivileged register has a
%-pseudo-operation name as a prefix.  For example, %hmcdper and %hm(),
or %hintp and %hi().

This patch fixes it by introducing a new table `perc_table' (for
%-table) that contains an entry for every %name supported by the
assembler, other than the general registers.  This table is used to
detect name collisions when the assembler tries to detect a %-pseudo-op.

This patch also fixes a related bug, making sure that v9a_asr_table and
hpriv_reg_table are sorted in reverse lexicographic order, as otherwise
the search code may fail.

gas/ChangeLog:

2016-06-17  Jose E. Marchesi  <jose.marchesi@oracle.com>

	* config/tc-sparc.c (priv_reg_table): Use NULL instead of the
	empty string to mark the end of the array.
	(hpriv_reg_table): Likewise.
	(v9a_asr_table): Likewise.
	(cmp_reg_entry): Handle entries with NULL names.
	(F_POP_V9): Define.
	(F_POP_PCREL): Likewise.
	(F_POP_TLS_CALL): Likewise.
	(F_POP_POSTFIX): Likewise.
	(struct pop_entry): New type.
	(pop_table): New variable.
	(enum pop_entry_type): New type.
	(struct perc_entry): Likewise.
	(NUM_PERC_ENTRIES): Define.
	(perc_table): New variable.
	(cmp_perc_entry): New function.
	(md_begin): Sort hpriv_reg_table and v9a_asr_table, and initialize
	perc_table.
	(sparc_ip): Handle entries with NULL names in priv_reg_table,
	hpriv_reg_table and v9a_asr_table.  Use perc_table to handle
	%-pseudo-ops.

		   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.
