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.

+# Invoke it as "bash compare-all-tests target1 target2 ... targetN".
+# Assumptions are:
+#
+# 1) that the base and patched compilers reside respectively in
+# base-$target-build and $target-build, where $target is the commandline
+# argument to compare-all-tests, and should match the variables in the
+# script itself so that the correct set of options is tested.  Both
+# compilers should be fully built (including target libraries).
+# 
+# 2) that the testsuite has been run on the base compiler (since it's
+# just compilation testing, using RUNTESTFLAGS=--target_board=basic-sim
+# usually suffices).
+# 
+# Tests that fail to compile on the base compiler are not compared.
