I have asked Julian about the status of this. The answer is that ARMv5 (let alone v4) "is not supported and possibly never will be". The current requirement is ARMv7. On the technical issues he says: "v6 is kind-of doable, although it gives some problems with SWP and SWPB. v5 would also be theoretically doable, although with more atomics problems and significantly poorer code generation due to non-availability of MOVW and MOVT for 32-bit constant generation." So although it could be done, there's more to it than just weeding out accidental v7isms, I'm afraid. Julian also raises the question of whether it's really worth doing for v6 and v5, from a performance aspect, given that it's only just about usable on an A8. He's also reluctant to add yet another configuration that valgrind has to support, test and maintain. -- Peter Maydell -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
