Hi,

Start Visual Studio, press F1 search #pragma , see runtime_checks and click it.
Than you see this
#pragma runtime_checks( "", off )
.
.
.
#pragma runtime_checks( "", restore )

I think I'll disable runtime check in this particular cpp file. In optimized release-mode the stack usage is 0 bytes (!).

Do you know a #pragma to disable runtime check?]]> Thu, 03 Dec 2009 09:09:26 +0000 http://forum.codejock.com/forum_posts.asp?TID=15746&PID=55358&title=stack-usage-on-recursive-call#55358 <![CDATA[Stack usage on recursive call : Hi,Every parameter need 4 Byte.CALL...]]> http://forum.codejock.com/forum_posts.asp?TID=15746&PID=55357&title=stack-usage-on-recursive-call#55357 Author: jimmy

Hi,

Every parameter need 4 Byte.
CALL need 4 Byte.
Save EBP need 4 Byte.
Save some other register need 3*4 Byte.

"Full runtime check" need 160 Byte. You can disable it.

if i have only 1 parameter it need 108 Byte.

i calculate
4 Byte        parameter
4 Byte        call
4 Byte        save ebp
4 byte        save this pointer
8 byte        for local variables
---------
24 Byte       

108 - 24 = 84 Byte too much ???
==================
i don't know more.

Please see attached sample. It demonstrates this.
 
It's totally sick! :(

Sure, but 68 bytes?! It makes it hard to debug my recursive function, since it blows the stack. 6 parameters yields 432 bytes, lol...
 
In Release-mode the recursive call is optimized away completely, so there is no need in rewriting my algorithm.

VS 2008 SP1.

Consider this function:

void foo(int x)
{
    foo(x + 1);
}
 
If I add a parameter "int y", I would expect the stack usage to increase by 4 bytes. However, in my case (in debug mode) it increases with 72 bytes.
 
Can somebody please explain this? 68 extra bytes is a LOT! :(
