From 6d9650191ae301dc545dd9fd0727c57ec935503e Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Fri, 6 May 2022 13:02:40 -0500 Subject: target/arm: Enable FEAT_DGH for -cpu max This extension concerns not merging memory access, which TCG does not implement. Thus we can trivially enable this feature. Add a comment to handle_hint for the DGH instruction, but no code.
