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.
