Is compiler dependent on OS?
A compiler that generates machine instructions is machine (or architecture) specific: an ARM and an x86 have different instruction sets, so the machine code would be very different for each, but it’s not necessarily OS-dependent (although it usually is, because different OSes have different calling conventions, etc.)
Is compiler a specific OS?
Not all compiler systems separate the compiler from the linker — if it’s one program, than it would be OS-specific. However, there are OS/machine independent compilers: most notably Java (and other JVM-based languages, such as Scala or Groovy).
What is the output of a compiler?
Traditionally, the output of the compilation has been called object code or sometimes an object module . (Note that the term “object” here is not related to object-oriented programming.) The object code is machine code that the processor can execute one instruction at a time.
Why we need a compiler in any operating system?
Source codes are human readable format but the system cannot understand it. So, the compiler is intermediate between human readable format and machine-readable format. The compiler will parse the source file and translate it into machine understandable object file.
Why is C system dependent?
C Compiler is platform dependent since it is closely linked to the OS kernel which is different for different OS. But over the years all OS’s come with pre-installed compilers and libraries that make it quite platform independent for basic programming.
Why is C language dependent?
Why is the C language platform-dependent, and why is Java platform-independent? The C compiler is designed to produce produces platform-specific, optimized code. But in Java, the bytecode i.e, remains consitent across the platforms and just need a platform dependent JVM for its execution.
Why are apps OS specific?
Most of the common operating systems use processor interrupts to access OS functions. Typical modern operating systems are not going to let a user program directly access any hardware. The system call used to write to the console will vary from OS to OS, so right there is one example of why software is OS specific.
Is the compiler part of the OS if not why not?
It’s not part of the OS because, well, it’s not part of the OS. An operating system is a way to manage multiple programs, but it doesn’t necessarily supply any particular program. A compiler is just a program – it reads files, does calculations, and writes files.
What is the output of interpreter?
1 Answer. There is no such thing as ‘output of the interpreter’. The interpreter executes compiled bytecode, or possibly source code, and its output is whatever the program being interpreted outputs. It doesn’t produce yet another object file.
What is the input and output of a compiler?
The compiler takes input data sets and libraries and produces various types of output, including object code, listings, and messages. The compiler also uses utility data sets during compilation.
What is the advantage of compiler?
Reduced system load. Protection for source code and programs. Improved productivity and quality. Portability of compiled programs.
What is the role of compiler?
A compiler is a special program that processes statements written in a particular programming language and turns them into machine language or “code” that a computer’s processor uses. Typically, a programmer writes language statements in a language such as Pascal or C one line at a time using an editor.
