--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I should note simplify_rotate in tree-ssa-forwprop.cc does not generate rotates
for types that don't have the same precision as the mode which was done since
that function was added and has the following comment:
/* Only create rotates in complete modes. Other cases are not
expanded properly. */
Oh fold_binary used to create these too. But the fix for PR 34971 changed that
and added an assert to expand_expr_real_1 to assert this case.
I should note we should document that behavior though.
Changing this to won't fix as the middle-end is asserting that we can't handle
it now.
