1.1 Introduction

The current version of the GNU binary utilities in use on the NetWinder is based on release 2.9.1 of the tools. H.J. Lu maintained a set of patches for Linux systems against the GNU 2.9.1 release. At this time H.J. Lu no longer actively maintains this set of patches. The ARM ELF patches in this release were put together by Phil Blundell, Pat Bierne and

1.2 Known Bugs - Version

Binutils is reported by Russell King to suffer from a case of the random changing opcode syndrome.

This is an old and fairly common problem. It occurs mainly with inter-section branches; this is one of the reasons the .text.init thing didn't use to work too well. There is a patch in Phil Blundell's directory on that helps a bit with this but a better solution is just to use the newer tools.
