Peter Maydell 8036c5b3de target/arm: Don't switch to target stack early in v7M exception return ... Currently our M profile exception return code switches to the target stack pointer relatively early in the process, before it tries to pop the exception frame off the stack. This is awkward for v8M for two reasons: * in v8M the process vs main stack pointer is not selected purely by the value of CONTROL.SPSEL, so updating SPSEL and relying on that to switch to the right stack pointer won't work * the stack we should be reading the stack frame from and the stack we will eventually switch to might not be the same if the guest is doing strange things Change our exception return code to use a 'frame pointer' to read the exception frame rather than assuming that we can switch the live stack pointer this early.
