8734 prof: variable 's_inv' set but not used
Review Request #685 - Created Oct. 27, 2017 and updated
../common/prof.c: In function 'main': ../common/prof.c:355:7: error: variable 's_inv' set but not used [-Werror=unused-but-set-variable] long s_inv; /* Inverse: i_inv(i) = */ ^~~~~ cc1: all warnings being treated as errors
I'd recommend that you move the line:
s_inv = pc_m/n_pc;
down inside the OLD_DEBUG macro. That's the only place where the variable is used. Then, enclose the declaration of the variable inside another instance of the same macro. With those changes, the unused variable error message should disappear under all conditions.
