Hi all,
It seems that AARCH64_TUNE_SLOWMUL somehow slipped from the arm backend into
the aarch64 one.
This macro is not used anywhere and I don't expect it will be used. It has been
there since
October 2012 i.e. when the port was first contributed.
This patch removes that and the relevant AARCH64_FL_SLOWMUL flag definition as
well.
Bootstrapped and tested on aarch64.
Ok for trunk?
Thanks,
Kyrill
