Incorrect execution result for simple program #60

Closed jserv closed 4 years ago

jserv commented 4 years ago

maze.c.gz is a simple maze generator written by Joe Wingbermuehle. The modified program can be parsed and executed by AMaCC. However, the program output is NOT correct. It was assumed to be kind of maze though. Also, the functionality to solve maze was incorrect.

After applying the potential fix #61 against modulo operator and replacing all occurrences of % with mod call, program maze.c is known to work.

$ /usr/bin/qemu-arm -L /usr/arm-linux-gnueabihf ./amacc  maze.c
