Instead of calling setup_frame() conditionally to a list of known targets, define TARGET_ARCH_HAS_SETUP_FRAME if the target provides the function and call it only if the macro is defined. Move declarations of setup_frame() and setup_rt_frame() to linux-user/signal-common.h Signed-off-by: Laurent Vivier <laurent@vivier.eu> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20180424192635.6027-21-laurent@vivier.eu>
