Subject: [PATCH][4.8 backport] Fix PR57735

Hi all,

The fix for PR57735 is in current trunk (for a different issue I think), just
needs a backport to 4.8.
It is r198462 by Richard Sandiford:

2013-04-30 Richard Sandiford <rsandifo@linux.vnet.ibm.com>
 	
 	* explow.c (plus_constant): Pass "mode" to immed_double_int_const.
 	Use gen_int_mode rather than GEN_INT.

Ok to backport to the 4.8 branch?

I've attached the testcase that exposed the ICE. I think the ChangeLog would
look like this:


2013-07-22  Kyrylo Tkachov  <kyrylo.tkachov@arm.com>

	PR target/57735
	Backport from mainline
	2013-04-30  Richard Sandiford  <rsandifo@linux.vnet.ibm.com>

		* explow.c (plus_constant): Pass "mode" to
immed_double_int_const.
		Use gen_int_mode rather than GEN_INT.
		
2013-07-22  Kyrylo Tkachov  <kyrylo.tkachov@arm.com>

	PR target/57735
	* g++.dg/ext/pr57735.C: New test.



Thanks,
Kyrill
