commit 9ceb3b8d8f6dd088f3efd590aae9e54a265e5b07
Author: Richard Biener <rguenther@suse.de>

streamline TARGET_MEM_REF dumping
The following streamlines TARGET_MEM_REF dumping building
on what we do for MEM_REF and thus dumping things like
access type, TBAA type and base/clique. I've changed it
to do semantic dumping aka base + offset + step * index
rather than the odd base: A, step: way.
2020-08-27 Richard Biener <rguenther@suse.de>
* tree-pretty-print.c (dump_mem_ref): Handle TARGET_MEM_REFs.
(dump_generic_node): Use dump_mem_ref also for TARGET_MEM_REF.
* gcc.dg/tree-ssa/loop-19.c: Adjust.
* gcc.dg/tree-ssa/loop-2.c: Likewise.
* gcc.dg/tree-ssa/loop-3.c: Likewise.
