WORKFLOW

Compilation Workflow

launch-script
-------------
* collect command line arguments
* write arguments to argument file
* invoke compiler
* delete arg file

compiler
--------
* read and evaluate argument file
* store arguments
* if information request
  * print information
  * exit
* if compilation request
  * read and evaluate configuration file
  * store configuration
  * determine module dependencies
  * write DEP file
  * determine compilation order from dependencies
  * for each module
    * perform lexical analysis and tokenisation
    * perform syntax analysis and build AST node
    * perform static semantic analysis
    * write AST file (S-expr representation)
    * write DOT file (graphical representation)
    * if definition module
      * write SYM file
      * write PIM/ISO DEF file
    * if implementation module
      * check consistency with corresponding SYM file
      * generate code from AST by template expansion
      * write PIM/ISO MOD file
  * invoke PIM/ISO compiler passing generated DEF or MOD file
  * purge unwanted intermediary files
  * determine and print statistics
  * exit
