gnusim8085

hangs on fedora every time program is compiled

Asked by Souvik Maji

I wanted to compile the following program which computes the factorial of a number stored in 2000h and stores the result in 2001h:
;MAIN
LXI SP,2999H
LXI H,2000H
MOV B,M
CALL FACT
INR L
MOV M,B
RST 1
;FACTORIAL
FACT: MOV A,B
LOOP: DCR A
CPI 01
RZ
CALL MUL
JMP LOOP
RET
;MULTIPLICATION
MUL: MOV C,A
LOOP1: ADD B
DCR C
JNZ LOOP1
MOV B,A
RET
;END

I changed the content of memory address 2000h to 5. If i try only asssemble program, it is assembled correctly, but if execute assembled and loaded program gnusim8085 hangs. Every time with no exception. Is this a bug or I have written something terribly wrong?

Have you tried debugging the program line by line to see if it is going in an infinite loop?

Yes, The program was going into an infinite loop.

Then that is not the fault of simulator application. :-) You need to correct your program.

Can you help with this problem?
