--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Oops, sorry, it is just SSA_NAMEs which are default definitions, so that is less than that; more than 32768 parameters to a function are unlikely, but one can have thousands of uninitialized SSA_NAMEs, or one can have tens of thousands of basic blocks. Even the number of bbs alone is what causes this on the function. And I forgot to change %ld to " HOST_WIDE_INT_PRINT_DEC " when printing the rank, fixed in my copy.
