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.

+; We use the term "base address" since that's what Knuth uses.  The base
+; address goes in a global register.  When addressing, it's more like
+; "base address plus offset", with the offset being 0..255 from the base,
+; which itself can be a symbol plus an offset.  The effect is like having
+; a constant pool in global registers, code offsetting from those
+; registers (automatically causing a request for a suitable constant base
+; address register) without having to know the specific register or the
+; specific offset.  The setback is that there's a limited number of
+; registers, and you'll not find out until link time whether you
+; should have compiled with -mno-base-addresses.
