It also seems a bit odd to move the cpu_unwind_state_data() prototype but not the similar cpu_restore_state() (which is also TCG-only). thanks -- PMM

OK I'll move them together (clearing "exec/cpu-common.h" is not easy...)

cpu_unwind_state_data() is specific to TCG accelerator, move it to "exec/translate-all.h". Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org> --- include/exec/cpu-common.h | 13 ------------- include/exec/translate-all.h | 12 ++++++++++++ 2 files changed, 12 insertions(+), 13 deletions(-)
