Simple Asembly to C convertion

[rockerjhr]

Im new to asembly in general and im trying to learn but i kind of not get a lot of stuff in IA32

how do I convert this:

pushl %ebp
movl %esp,%ebp
movl 8(%ebp),%edx
movl 12(%ebp),%eax
movl %ebp,%esp
movl (%edx),%edx
addl %edx,(%eax)
movl %edx,%eax
popl %ebp
ret

to C ?

what i got from this was something like

int fun6(int *ap, int *bp)
{


  *ap =   *ap + *bp   ;



}

and how do i convert this:

pushl %ebp
movl %esp,%ebp
movl 8(%ebp),%eax
sall $4,%eax
addl 8(%ebp),%eax
addl %eax,%eax
movl %ebp,%esp
popl %ebp
ret

to C ?

and for this one something like

int fun6(int ap)
{

int x  = ap << 4 ; 
x = x + ap ; 
x = x + x ; 

return x  ; 



}
