FOR COMPILATION

• well.cs.ucr.edu
  • OR -
• gcc version 4.1.2 20080704 (Red Hat 4.1.2-55)
• flex version 2.5.4
• bison (GNU) version 2.3

FOR EXECUTION

• bolt.cs.ucr.edu
  • OR -
• gcc version 4.8.5 20150623 (Red Hat 4.8.5-11) (GCC)

Examples There are couple of example code files included in this repo. They can be used to make compiler parser work.
Running the Code The code can be run by following the sequence of commands:

make clean
make
./mini_l *filename*.min > filename.mil   
/*This performs lexical analysis, Parsing, Semantic Analysis and MIL Code generation on the file containing mini l code in filename.min, and redirects the MIL code output to filename.mil*/
./mil_run filename.mil < input.txt
/*executing the generated MIL code with input provided from input.txt*/

Known Bugs

1. [FIXED]Cannot read multiple input items from the same line
2. [FIXED]Function lookups not implemented
