--- Comment #16 from Julian Seward <jsew...@acm.org> ---
I would be happy to make a generalised version of Maran's fixes,
so as to get arm{32,64} working on these cores. I don't really
want it to be the default implementation though, since we lose
correctness w.r.t. the ABA problem against other processes in
shared memory, relative to using the existing implementation.
Ideally I'd like to have a command line argument
--fallback-llsc=[no|yes|auto]
to enable the alternative implementation when necessary, with
it defaulting to |auto| so as to not to have to bother the user
with selecting flags for what is an arcane detail. So the real
question here is how to reliably auto-detect when the fallback
implementation should be used.
