Lab – Construction of Trees

What do trees look like?

for some simple programs

Examine Translate/Translate.java

for loops and array indexing

Write

while loop & record field dereference translation

Note – these slides are available on the web

Compile this with Translate.Main

SEQ(

MOVE(

    TEMP t2,

    CONST 3),

MOVE

    TEMP t2,

    BINOP( PLUS,

                TEMP t2,

                CONST 1 )))

Your work…

You might notice that the code for WhileExp and FieldVar is missing – you are to write these

Consider what code you need to construct for each first

With reference to what we’ve looked at, write the translation code for these two constructs
