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.

+   Origin: PR debug/37801
+
+  Abstract instances (DW_TAG_subroutines having the DW_AT_inline attribute)
+  of second and first were having a DW_TAG_lexical_block DIE wrongly
+  representing the inlined calls to third (in second) and to
+  second (in first). At the same time, main didn't have children
+  DW_TAG_inlined_subroutine DIEs representing the inlined calls to
+  first, second and third.
+
+  The ideal goal here is to test that we have no superfluous
+  DW_TAG_lexical_block DIE anymore, that abstract instances DIEs have
+  no descendant DIE with a DW_AT_abstract_origin attribute, and that main has
+  properly nested DW_TAG_inlined_subroutine DIEs for third, second and first.
