Which of the following is the function of the semantic analysis phase of compilation proc 

Detailed Solution for Test: Loop Unrolling - Question 1
  • The semantic analysis phase of compilation is responsible for ensuring that the source code is semantically correct. This involves checking for type consistency, scope resolution, and type conversions.
  • Type conversion is a critical part of the semantic analysis phase as it ensures that operations are performed on compatible data types.

Cross compiler is used in Bootstrapping.
Detailed Solution for Test: Loop Unrolling - Question 4

Bootstrapping to a new platform. When a software is developed for a new platform, a cross compiler is used to compile necessary tools such as the OS and a native compiler.

Is GCC a cross Compiler ?
Detailed Solution for Test: Loop Unrolling - Question 5

GCC, a free software collection of compilers, also can be used as cross compile. It supports many languages and platforms.

The __________ is a technique for building cross compilers for other machines.
Detailed Solution for Test: Loop Unrolling - Question 6

The Canadian Cross is a technique for building cross compilers for other machines. Given three machines X, Y, and Z, one uses machine X (e.g. running Windows XP on an IA-32 processor) to build a cross compiler that runs on machine Y (e.g. running Mac OS X on an x86-64 processor) to create executables for machine Z.

__________ was developed from the beginning as a cross compiler.
Detailed Solution for Test: Loop Unrolling - Question 7

Free Pascal was developed from the beginning as a cross compiler. The compiler executable (ppcXXX where XXX is target architecture) is capable of producing executables for all OS of the same architecture.

What will be output of the following code?

#include<stdio.h>
intmain(){
printf("%d\t",sizeof(6.5));
printf("%d\t",sizeof(90000));
printf("%d",sizeof('A'));
return 0;
}
Detailed Solution for Test: Loop Unrolling - Question 8

 GCC compilers (32 bit compilers) size of:
double is 8 byte
long int is 8 byte
Character constant is 2 byte.

Test: Loop Unrolling - Question 9

What will be output of the following c code? ( according to GCC compiler)

#include<stdio.h> int main()
{ signed x;
unsigned y;
x = 10 +- 10u + 10u +- 10;
y = x
; if(x==y)
printf("%d %d",x,y);
else if(x!=y)
printf("%u %u",x,y);
return 0;
}
Detailed Solution for Test: Loop Unrolling - Question 9

 Consider on the expression:
x = 10 +- 10u + 10u +- 10;
10: It is signed integer constant.
10u: It is unsigned integer constant.
X: It is signed integer variable.
As we know operators enjoy higher precedence than binary operators. So
x = 10 + (-10u) + 10u + (-10);
= 10 + -10 + 10 + (-10);
= 0
So, Corresponding signed value of unsigned 10u is +10.

What will be output of the following c code?

#include<stdio.h> int main()
{ const int *p;
int a=10;
p=&a;
printf("%d",*p);
return 0;
}
Detailed Solution for Test: Loop Unrolling - Question 10

In the following declaration
const int *p;
p can keep address of constant integer.
