+The sourcery gnutools
+=====================
+
+A stripped down version of the sourcery hexagon gnutools is downloaded from [my xs4all page](https://itsme.home.xs4all.nl/hx-2012.03-v2.tar.gz). This version does include some patches to silence some compiler warnings, and work around a problem in the original code where occasionally the disassembler would crash.
+The original archive is quite large ( 140M ) and can be found [here](https://sourcery.sw.siemens.com/GNUToolchain/package14127/public/hexagon/sourceryg++-2012.03-151-hexagon.src.tar.bz2). 
+The GPL/LGPL license files are included in the tar file.
+
+Preconfigured bfd.h and config.h files are included in this source archive.
