The stringcmp.c describes a MISRA$-$C compliant implementations on ARM LPC$17$xx processor. Please write an ARM assembly language to implement the code. If you use any registers other than r$0-$r$3,$ you need to save them in the stack, $($using instructions push $\{$r$4-$r$7\},$ for example to save registers r$4,$ r$5,$ r$6,$ and r$7,$ pop$\{$r$4-$r$7)$ is the instruction to restore them$).$ In your main.c function, please run the stringcmp results for the following strings.

stringcmp$("$abc$",$ "def"$)<mtext\; id="EditorElement\_548303"></mtext><mn\; id="EditorElement\_548304">0</mn>$

stringcmp$("$abc$",$ "abcd"$)<mtext\; id="EditorElement\_548334"></mtext><mn\; id="EditorElement\_548335">0</mn><mtext\; id="EditorElement\_548336"></mtext><mi\; id="EditorElement\_548337">/</mi><mi\; id="EditorElement\_548338">/</mi>$ null character is less than $\text{'}$d$\text{'}$

stringcmp$("$abc$",$ "ABC"$)>0//\text{'}$a$\text{'}>\text{'}$A$\text{'}$ in ASCII

stringcmp$("$abc$",$ "abc"$)==0$

The C code in main.c looks like this,

printf$("$comparions abc def $\%4$d

$",$ stringcmp$("$abc$",$"def"$))$;

printf$("$comparions abc abcd $\%4$d

$",$ stringcmp$("$abc$",$"abcd"$))$;

printf$("$comparions abc ABC $\%4$d

$",$ stringcmp$("$abc$",$"ABC"$))$;

printf$("$comparions abc abc $\%4$d

$",$ stringcmp$("$abc$",$"abc"$))$;
