(record_store, check_mem_read_rtx): Likewise. For non-const-or-frame addresses pass base->val_rtx as mem_addr, for const-or-frame addresses canon_base_addr of the group, plus optional offset. (struct group_info): Rename canon_base_mem to canon_base_addr. (get_group_info): Set canon_base_addr to canon_rtx of base, not canon_rtx of base_mem. * gcc.dg/pr39794.c: New test.
