A “short list” of embedded systems

The frontend

•All file accesses and incremental compilation are encapsulated in FileLoader:

–loads files from disk

–check syntax of the program

–builds the ASTs

loadCompileUnit(filename,pass)

loadCompileUnit(pkg,class,pass)

–

•Tasks of semantic passes

–check semantics of the program

–add semantic annotations

–refine the abstract syntax trees, e.g. Name ® FieldAccess
