--- Comment #10 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Comment on attachment 40136 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=40136 move ptrdiff_type_node initialization to build_common_tree_nodes So, what do you want to do for VRP in the vms case where size_t is unsigned int (32-bit) and ptrdiff_t is long long int (64-bit)? Shall we use VARYING range in that case, or 0 to SIZE_MAX / 2, something different? What about the hypothetical case where size_t would be larger than ptrdiff_t?
