Oh yeah,

And I also forgot to add that one of the real tricks is finding reliable ways to coerce the compiler into constant-folding the coefficients, not merely getting the math unrolled. This...

Yes. I agree, I agree and I agree with all three sections of your text.

And I really do like your C-style array suggestion. In fact, I'm just in the process of seeing how it is unrolled or even...

With pointer : Yes and no.
With std::array : Yes.

I am simultaneously investigating compiler-time unrolling in combination with compiler-time constants. The constants in a const...

No, that one did not work.

But this cool tidbit works with GCC. I tested it with GCC 4.5.2



#include <initializer_list>

template<const unsigned order>
struct orderN_math

Hello,

It's been a while since I checked in here.

Is it possible to use an array of constant values as a template parameter. I am writing preliminary benchmark code for ISO/IEC 14882:2011, so I...

Thanks. All of this helped.

Sincerely, Chris.

I can understand that. In fact, for a day or so, I was content to just figure it along those lines.

But is this really an implementation detail? What if someone wanted to use some ctor/dtor...

Hello,

I am studying subtle differences in the implementation of std::vector<T> for Microsoft and GCC compilers.

The program shown below gives different output for the two compilers. You need...

Quicker than a blitz as usual, Paul.
Thanks.

Hi Gurus,

I know, I must be a dork for not knowing it. But how do you delete a pointer created with placement-new? I'm trying to get with the sample below and I keep thinking that there should be...

Thanks for the further suggestions.

The types I am creating with placement new never delete. They also don't alocate any further resources internally.

It's kind of a funny region --- the world...

Thanks. Chris.

Lindley, I can't add to your rep any more because the box won't let me. Wants me to spread it around.

But you rock. All the other gurus too.

Bye, Chris.

Oh. I have heard of those, variadic templates. They came up in a previous post.

Maybe I'll go into the intricate depths of the templates and try it again.

Maybe I can make it prettier the next...

Yes, what an astute observation. Thank you.

I tried it that way a few times, but lost confidence because of the complexity of the solution details.

At first, I actually did make a global...

Right now my custom buffer returns zero if the call to placement new exceeds the available memory in the buffer. Perhaps I should add to my custom buffer a public member which can be queried...

May I clarify my question now that I have worked on this a while?

If my custom buffer returns (void*) 0u, will placement new correspondingly return 0?

For a bit of background: I am working on...

Hello Gurus,

Could you please clarify some technical isses regarding C++ evolution?

Background::thumb:

There is ISO/IEC 14882:2003, also known as C++ 2003.
There is also ISO/IEC...

So just one more thing...

Can I coerce placement new to return 0 if my custom buffer is full?

If so, how?

Sincerely, Chris.

Oh... Silly me! You guys mean it's already there.

I got it.

Please disregard my last post.

Thanks so much.

Sincerely, Chris.

Yes, thank you.

[Edited]: Disregard previous text.

Hello Gurus,

I'm working on a few generic code sequences which should in some ways mimic the functionality of global operator new. I believe the code might be considered in bad taste. However, I...

Thanks superbonzo.

I have used your suggestion, adapted to the application.
The language issues are working out!
The application still has a problem, but that is an unrelated issue.

Always a...

Hi Gurus,

Howdy, I've been gone a while.

I would like to make specializations of a template subroutine within the specialization of a template struct.


I know that the standard does not...

Makes sense. Thanks.

Best Regards, Chris
