Compiler Design

Which of the following is NOT possible to realize if activation record is static

• Passing parameters

• Creating local variables

• Supporting recursion

• None of the other options

Control link points to the

• Current activation record

• Parent activation record

• Child activation record

• None of the other options

Intermediate code generation for a compiler is

• Must

• Optional

• depends on language

• none of the above

P-code is used for

• Stack-based machine

• Accumulator based machine

• Two operand addresses

• None of the other options

In the activation record, local variables can be accessed from frame pointer with offset value

• positive

• negative

• May be positive or negative

• Cannot be accessed

Access link points to the

• Current activation record

• Parent activation record

• Child activation record

• None of the other options

If pointer is supported in the high-level language,

• Must also be supported in the intermediate language

• May not be supported in the intermediate language

• Depends on language

• None of the other options

An intermediate language should be

• Close to target machine

• Machine independent

• All operators of high-level language supported

• All of the other options

For the rule S -> L := E, if L is a single variable, L.place is equal to

• Null

• Some value

• constant

• None of the other options

For Boolean variable B, B.truelist contains

• List of locations at which B is true

• List of locations to jump to if B is true

• List of locations at which B is true and the locations to branch to

• None of the other options
