From 1db3632a14f44e243068bcf89bcf0739b657972b Mon Sep 17 00:00:00 2001 From: Matheus Ferst Date: Fri, 17 Sep 2021 08:47:50 -0300 Subject: target/ppc: add LPCR[HR] to DisasContext and hflags Add a Host Radix field (hr) in DisasContext with LPCR[HR] value to allow us to decide between Radix and HPT while validating instructions arguments. Note that PowerISA v3.1 does not require LPCR[HR] and PATE.HR to match if the thread is in ultravisor/hypervisor real addressing mode, so ctx->hr may be invalid if ctx->hv and ctx->dr are set.
