Performance, for(int i...) vs for(i...)

[lab at kayohamid dot net]

Hello, I like performance, and until last month i follow what I see on 
the web to do better coding for performance, like:

- Avoid i++, use ++i and so on.

But now i'm using the assembly (-S) code generated to see if somethings 
is correct, and today i'm investigating this:

int i;
for(i = 0;....);

vs

for(int i = 0;...);

I make 2 codes:

----
int main()
{
int i;
for(i = 0; i < 10; i++) {}
}

----

int main()
{
for(int i=0;i<10;i++) {}
}

----

the result of forin.c and forout.c is the same:

        .file   "forin.c"
        .text
        .globl  main
        .type   main, @function
main:
.LFB0:
        .cfi_startproc
        pushl   %ebp
        .cfi_def_cfa_offset 8
        .cfi_offset 5, -8
        movl    %esp, %ebp
        .cfi_def_cfa_register 5
        subl    $16, %esp
        movl    $0, -4(%ebp)
        jmp     .L2
.L3:
        addl    $1, -4(%ebp)
.L2:
        cmpl    $9, -4(%ebp)
        jle     .L3
        movl    $0, %eax
        leave
        .cfi_restore 5
        .cfi_def_cfa 4, 4
        ret
        .cfi_endproc
.LFE0:
        .size   main, .-main
        .ident  "GCC: (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3"
        .section        .note.GNU-stack,"",@progbits

Seeing this, can I say that using int inside the for or outside for is 
the same? Have no difference on performance?
