C language into LC-3 Assembly Language

Assembly for an Instruction 2
0.0/10.0 points (graded)
Suppose that a program contains this function
int f(int p, int q) {
int a = 5;
int b = 6;
int c= 7+b;
return 84:
}
and suppose that the assembled program ends with
GLOBAL_DATA_START
9
LC3_first
.FILL #6
.FILL X302A
.FILL # 84
.FILL #7
.FILL #6
.FILL #5
.END
What five lines of assembly code will the LC-3 compiler usually produce for the line int c = 7+b; in this context?
Extra spaces will not invalidate an answer. If the compiler can choose between alternative intermediate registers, so can you without invalidating your answer. You may use hex or decimal for
numbers; for example, x-9 and #-9 should work for the negative offset minus nine (but do not put a minus sign to the left of the x or the # ).
