SILC

A compiler for the Simple Integer Language (SIL) that reads a SIL source program, and generates instructions for a target machine known as the Simple Integer Machine (SIM).
Source Language (SIL) description can be found at [http://athena.nitc.ac.in/~kmurali/Compiler/sil.html]
Target Machine (SIM) Architecture description can be found at [http://athena.nitc.ac.in/~kmurali/Compiler/sim.html]

FolderDescription

Instructions

  1. Compile the compiler source programs using the Makefile present in Main/. In the terminal, write

     $ cd Main/
    $ make all
  2. Using the object file sil that is created, compile any of the SIL source programs present in Main/. In the terminal, write

     $ ./sil SILsource1
     
  3. The SIL source program will be executed. Also, the SIM instructions that are generated will be stored in file SIMcode

  4. The instructions in the file SIMcode are executed using the SIM simulator present in Main/SIM_Simulator/. To execute the generated SIM instructions, write in the terminal

     $ cd SIM_Simulator/
    $ make all
    $ ./sim ../SIMcode
