I suppose to write a grammar file for assembly language program by using Java in ANTLR .. but I don't know from where should I start .. and what should I do.. I am lost..
any expert with this subject could help me :(
I have read a lot but actually there is no time for me to read more.. and I suppose to work now before the dead line.. I am afraid :(
it's 3 years ago since I left Uni.. and I just came back to study..
seems I need a lot of help from U ..
the code what should I write the copiler for is :
SUB R1,R1,0 LD R1,R1,1024 SUB R2,R2,0 LD R2,R2,1025 SUB R3,R3,0 LD R3,R3,1023 MUL R1,R2,0 DIV R1,R3,0
