Create a MIPS program based in the proposed C program:

void Fred()

{

x=x+1;

Bill();

}

void Bill()

{

x=x+2;

Charlie();

}

Void Charlie()

{

x=x+3;

}

int x=0;

main()

{

Fred();

}

Here is an example of a mips procedure call: Information that may be lost is stored on the stack. Note the

convention of who (the caller or the callee) saves the information. There may be error!

.text

.globl

main

main:

subu

$sp,$sp,32

# Example of code required by calling protocol

sw

$ra,20($sp)

# for saving registers (uses stack).

sw

$fp,16($sp)

addu

$fp,$sp,28
