C to y86

I don't know if this is the correct place to post this, but here goes...

I am trying to get this program:

Code:

---

#include <stdio.h>

int main() {

        int A[4]={1,2,3,4};
        int B[4]={4,3,2,1};

        int dot;
        dot=A[0]*B[0]+A[1]*B[1]+A[2]*B[2]+A[3]*B[3];

        printf("%d", dot);

}

---

to y86. This is what I have:

Code:

---

        .pos 0


.LC0:
        .string        "%d\n"
        .text
.globl main
        .type        main, @function
main:
        pushl        %ebp
        rrmovl        %esp, %ebp
        andl        $-16, %esp
        pushl        %ebx
        subl        $76, %esp
        irmovl        $1, 44(%esp)
        irmovl        $2, 48(%esp)
        irmovl        $3, 52(%esp)
        irmovl        $4, 56(%esp)
        irmovl        $4, 28(%esp)
        irmovl        $3, 32(%esp)
        irmovl        $2, 36(%esp)
        irmovl        $1, 40(%esp)
        mrmovl        44(%esp), %edx
        mrmovl        28(%esp), %eax
        imull        %eax, %edx
        mrmovl        48(%esp), %ecx
        mrmovl        32(%esp), %eax
        imull        %ecx, %eax
        leal        (%edx,%eax), %ebx
        mrmovl        56(%esp), %edx
        mrmovl        40(%esp), %eax
        imull        %eax, %edx
        mrmovl        52(%esp), %ecx
        mrmovl        36(%esp), %eax
        imull        %ecx, %eax
        leal        (%edx,%eax), %eax
        leal        (%ebx,%eax), %eax
        rmmovl        %eax, 60(%esp)
        irmovl        $.LC0, %eax
        mrmovl        60(%esp), %edx
        rmmovl        %edx, 4(%esp)
        rmmovl        %eax, (%esp)
        call        printf
        addl        $76, %esp
        popl        %ebx
        rrmovl        %ebp, %esp
        popl        %ebp
        ret

        .pos 0x100

But I am getting missing colon errors on my simulator. There aren't colons in y86 other than the loops, any suggestions?

It looks like you just took the output of gcc -S and modified some instruction names. Have you verified that this is valid input to the assembler you're using?

I haven't, but I followed step by step instructions using the assembler.

I just learned that leal and imull aren't commands, so it'll give me that error. However, I don't know how to convert the x86 commands leal and imull to y86. My book is terrible.

You have to look up what they do and find alternate commands for them. There are plenty of references to both languages on the net.
