--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The ICE started with the PR92860 change.
sh_option_optimization_table has:
static const struct default_options sh_option_optimization_table[] =
{
{ OPT_LEVELS_SIZE, OPT_mdiv_, SH_DIV_STR_FOR_SIZE, 1 },
{ OPT_LEVELS_0_ONLY, OPT_mdiv_, "", 1 },
{ OPT_LEVELS_ALL, OPT__param_simultaneous_prefetches_, NULL, 2 },
{ OPT_LEVELS_NONE, 0, NULL, 0 }
};
and so wants to change sh_div_str for -Os or -O0.
But I think SH doesn't support target attribute.
Does sh_override_options_after_change need to do something, or is target
attribute handling now required for backends that do want to change some Target
options based on optimization levels?
