UNIT - 5 A Code Generation Quiz

What is the main concern in the design of a code generator?

• To optimize memory allocation

• To convert high-level code into machine code

• To analyze control flow in the program

• To define variable types

In the context of code generation, what does the term "target machine" refer to?

• The hardware architecture for which the code generator produces machine code

• The program that manages runtime execution

• The programming language used for compilation

• The algorithm for converting source code to assembly

Which of the following is an important task during register allocation?

• Assigning memory locations to variables

• Ensuring that registers are used efficiently

• Handling syntax errors

• Translating source code into intermediate code

What is a basic block in the context of compiler design?

• A sequence of instructions with no branches

• A group of related functions

• A memory management unit

• A variable declaration

What is a flow graph used for in code generation?

• To optimize memory access

• To represent the control flow of a program

• To show how different functions interact

• To define the program's data types

Which of the following is a technique used to optimize basic blocks?

• Constant propagation

• Function inlining

• Dead code elimination

• Register renaming

What does register allocation involve?

• The mapping of program variables to specific registers

• The storage of constant values in registers

• The translation of machine code into assembly

• The compilation of high-level code

Which of the following is true about basic blocks?

• They always contain conditional branches

• They have no internal jumps, and control only enters at the beginning

• They represent entire functions

• They are used to define data structures

What is the purpose of a simple code generator?

• To optimize the target machine code

• To generate machine code from intermediate representations

• To handle the source code errors

• To analyze the flow of data in the program

In code generation, why is register assignment important?

• To ensure that variables are stored in memory rather than in registers

• To minimize the number of registers used and improve execution speed

• To reduce the size of the code generated

• To allocate memory for dynamic variables
