Shouldn't convert_scalars_to_vector call free_dominance_info?


convert_scalars_to_vector in i386.c calls

calculate_dominance_info (CDI_DOMINATORS);

Shouldn't it call

free_dominance_info (CDI_DOMINATORS);

after it is done like other places where calculate_dominance_info is used?
When I extend the STV pass to 64-bit and put the 64-bit STV pass before
the CSE pass, I run into

gcc_assert (!dom_info_available_p (CDI_DOMINATORS));
