--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
While changing mdiv= from accepting a string to Enum(something) might be worth
it, wouldn't that be GCC 13 material? I think right now -mdiv= accepts random
garbage like -mdiv=foobar . There is also an enum already but there is no 1:1
mapping between what is assigned to sh_div_strategy from what is in sh_div_str,
and sh_div_strategy probably should be a TargetVariable.
Anyway, wouldn't the following be enough for now to just do:

The testcase doesn't ICE with it anymore, and e.g. i386.opt has various Save
strings too.
