From 4c4c8723684b1b2cd0dfdf5e0685f35642bde253 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Thu, 23 Nov 2006 00:46:42 +0100 Subject: [POWERPC] Prepare for spu disassembly in xmon In order to do disassembly of spu binaries in xmon, we need to abstract the disassembly function from ppc_inst_dump. We do this by making the actual disassembly function a function pointer that we pass to ppc_inst_dump(). To save updating all the callers, we turn ppc_inst_dump() into generic_inst_dump() and make ppc_inst_dump() a wrapper which always uses print_insn_powerpc(). Currently we pass the dialect into print_insn_powerpc(), but we always pass 0 - so just make it a local.
