Re: instantiation point discussion

Tech-Archive recommends: Speed Up your PC by fixing your registry

g++ is free. Use the MingW version on Windows.

To test fine points of the language, use the free online demo of Comeau. Note that it doesn't link. Or buy the full compiler.

Non-trivial template code should always be tested with at least two compilers.

* George:
Thanks Tim,


I will improve next time. Sometimes I want to get more knowledge, but I only have MSVC at hand and I can not try two-phase name lookup compiler.

But there are cases which I should make tests before asking question, or making enough tests. I will improve this points.


regards,
George

I'm not enough of a C++ language lawyer to know whether you can actually
say "never", but in this case it is certainly true.

3. If the sample looks like this, g(double) will be called when we call f (2.0)?
George, here is yet ANOTHER case where it would have been a hundred times
faster for you to just TRY it. It took me 60 seconds to cut-and-paste your
code to a cpp file, compile it with /FAsc, and look at the resulting .cod
file to find the answer.
