PR rtl-optimization/39794
* alias.c (canon_true_dependence): Add x_addr argument. * rtl.h (canon_true_dependence): Adjust prototype. * cse.c (check_dependence): Adjust canon_true_dependence callers. * cselib.c (cselib_invalidate_mem): Likewise. * gcse.c (compute_transp): Likewise. * dse.c (scan_reads_nospill): Likewise. (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. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@146669 138bc75d-0d04-0410-961f-82ee72b054a4
