Lu <hongjiu.lu@intel.com> PR middle-end/35897 * dse.c (store_info): Change positions_needed to unsigned HOST_WIDE_INT. (lowpart_bitmask): New. (record_store): Cast to unsigned HOST_WIDE_INT for positions_needed. Assert width <= size of positions_needed * CHAR_BIT. Call lowpart_bitmask to initialize positions_needed. (check_mem_read_rtx): Use unsigned HOST_WIDE_INT on mask. Call lowpart_bitmask to set mask.
