Rather than include helper.h with N values of GEN_HELPER, include a secondary file that sets up the macros to include helper.h. This minimizes the files that must be rebuilt when changing the macros for file N. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <rth@twiddle.net>
