The set of compile-time optimizations has almost not changed since at least 15 years ago. > And I think there are some potential optimization if we can limit some > debugging/introspecting features, like some C variables are "optimzed away" > in gdb when > we use -O option. You can think it, but where's the proof? Or at least the design document for these optimizations? How do you explain that Victor's attempt at static optimization failed?
