From 69d4d6e5fd9f4e805280ad831932c3df7b9d7cc7 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Thu, 20 May 2021 13:50:45 +0000 Subject: powerpc: Don't use 'struct ppc_inst' to reference instruction location 'struct ppc_inst' is an internal representation of an instruction, but in-memory instructions are and will remain a table of 'u32' forever. Replace all 'struct ppc_inst *' used for locating an instruction in memory by 'u32 *'. This removes a lot of undue casts to 'struct ppc_inst *'. It also helps locating ab-use of 'struct ppc_inst' dereference.
