From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001
From: upstream source tree <ports@midipix.org>
Date: Sun, 15 Mar 2015 20:14:05 -0400
Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified
 gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream
 tarball.

downloading a git-generated archive based on the 'upstream' tag
should provide you with a source tree that is binary identical
to the one extracted from the above tarball.

if you have obtained the source via the command 'git clone',
however, do note that line-endings of files in your working
directory might differ from line-endings of the respective
files in the upstream repository.

+! { dg-do run }
+! Test the fix for pr22146, where and elemental subroutine with
+! array actual arguments would cause an ICE in gfc_conv_function_call.
+! This test checks that the main uses for elemental subroutines work
+! correctly; namely, as module procedures and as procedures called
+! from elemental functions. The compiler would ICE on the former with
+! the first version of the patch.
+!
+! Contributed by Paul Thomas   <pault@gcc.gnu.org>
