From 5ce4f35781028ce1aee3341e6002f925fdc7aaf3 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Tue, 17 Dec 2013 19:42:31 +0000 Subject: target-arm: A64: add set_pc cpu method When executing translation blocks we need to be able to recover our program counter. Add a method to set it for AArch64 CPUs. This covers user-mode, but for system mode emulation we will need to check if the CPU is in an AArch32 execution state.
