No, I meant that if the table is used in the different object files, will the copies of the tables be compiled in several different instances? And I can't see the part which makes the tables static in this patch... > I feel it would be easier to let the compiler do it's job rather > than do optimizations we don't need to do and which will complicate > the code quite a bit. I haven't tend to optimize it, but just encapsulate it, to hide from other parts. Thank you, -- Masami HIRAMATSU Software Platform Research Dept.
