GATE CSE 2024 Set 2

MCQ (More than One Correct Answer)

-0

Which of the following statements is/are FALSE?

An attribute grammar is a syntax-directed definition (SDD) in which the functions in the semantic rules have no side effects

The attributes in a L-attributed definition cannot always be evaluated in a depth-first order

Synthesized attributes can be evaluated by a bottom-up parser as the input is parsed

All L-attributed definitions based on LR(1) grammar can be evaluated using a bottom-up parsing strategy

GATE CSE 2023

MCQ (Single Correct Answer)

-0.33

Consider the following statements regarding the front-end and back-end of a compiler.

S1: The front-end includes phases that are independent of the target hardware.

S2: The back-end includes phases that are specific to the target hardware.

S3: The back-end includes phases that are specific to the programming language used in the source code.

Identify the CORRECT option.

Only S1 is TRUE.

Only S1 and S2 is TRUE.

S1, S2 and S3 are all TRUE.

Only S1 and S3 are TRUE.
