IFJ21 compiler, that creates IFJcode21 from IFJ21 (the superset of Teal) source.
This project was assigned in Formal Languages and Compilers subject (IFJ) at VUT FIT.
Final evaluation:
Lexical analysis (error detection): 94 % (164/174)
Parsing (error detection): 97 % (188/192)
Semantic analysis (error detection): 99 % (292/294)
Semantic/runtime errors (detection): 100 % (62/62)
Interpretation of compiled code (basics): 96 % (295/305)
Interpretation of compiled code (expressions, builtin functions): 95 % (189/198)
Interpretation of compiled code (complex): 72 % (247/343)
Extensions:
BOOLTHEN 0 % (0/170)
CYCLES 0 % (0/150)
FUNEXP 83 % (125/150)
OPERATORS 84 % (42/50)
Total evaluation (without extensions): 91 % (1437/1568)

Authors of ic21int are teachers in IFJ course.
Use make and enclosed Makefile command to build compiler. GCC is used wihtout any optimization.
If you are going to compile program manually, please ensure that shortcut evaluation is turned on.
After compilation you can run program by:
./IFJ21 < your_code.tl > result.ifj
Then you can run compiled code by ic21int.
If everything goes well compiler returns 0.
1 - Lexical Error (e. g. invalid character)
2 - Syntax Error
3-7 - Semantic Errors
8 - Bad usage of nil
9 - Zero division (when operation /, //, % are used)
Errors 8, 9 can ocurr during compilation as well as during interpretation.
There are simple nil and zero division detection in compiler. To turn it off check precedence_parser.h.
Our compiler also prints warnings to stderr, if performs implicit actions (at least some of them).
You can turn this feature off in files precedence_parser.h, parser_topdown.h, generator.h.
