Bootstrapping a compiler to multiple machines involves creating a portable and self-sufficient compiler that can generate code for different architectures. This typically starts with a source code written in a high-level language, which is compiled on a primary machine to produce an executable for the target machine. The process may include cross-compilation, where the compiler runs on one architecture but generates code for another. Once the target machine has the compiler, it can then compile itself and further optimize for its architecture, enabling the development of software across various systems.

What is the role of a compiler?
The compiler converts source code (the stuff the programmer wrote and is human readable) and converts it to machine code that the computers CPU can understand. The conversion is used to make an executable program. The compiler can also make libraries but libraries are not executable by them selves.
Where is compiler in jvm?
In the Java Virtual Machine (JVM), the compiler is not a specific component but refers to the Just-In-Time (JIT) compiler. The JIT compiler is part of the JVM that converts bytecode, generated by the Java compiler (javac), into native machine code at runtime. This process allows Java applications to run more efficiently by optimizing performance during execution, rather than ahead of time. Additionally, the JVM also includes an interpreter that can execute bytecode directly, but the JIT compiler enhances speed by compiling frequently executed code paths.
Is jvm a compiler?
Basically they do the same: converting from one level of language into another. A compiler converts high level language (programming language like java) into machine-language. That is language a computer understands. An interpreter converts high level language into an intermediate level. When a program is exectuted, that intermediate level is reconverted to machine language.
What is pass in compiler design?
There are two types of compilers one-pass and multi-pass. Pass means that some of inner operations are repeated several times. If we have one-pass compiler and this source code: i++; i++; i++; Inside compiler it would generate: i = i + 1; i = i + 1; i = i + 1; If compiler would be two-pass: i = i + 3; The more passes compiler has, the better optimized code it can generate, but it is slower because it must repeat some steps again.
Why you need compiler?
You don't need if you don't want to develop computer programs. But if you want you should use it, for you can not make programs without a compiler. Compiler is the programs that makes the computer program out of the code
Example of compiler converting the high level language into machine language?
Compiler Compiler is the correct answer. It's a programme that converts source code written in a high-level programming language into machine code for a particular computer architecture. It translates high-level language into machine language, to put it simply. To learn more about data science please visit- Learnbay.co

Difference Between interpreter and compiler in java application?
Due to platform independence, a Java compiler will interpret Java source code into Java Byte Code and pass to the JVM, which will pass machine understandable code through to cpu. (clarification needed).A conventional compiler converts source code directly to machine code.(clarification needed).
What made grace hopper want to create the compiler?
Grace Hopper was motivated to create the compiler to simplify programming and make it more accessible. She recognized the challenges programmers faced when writing in machine language and aimed to develop a tool that would translate high-level language into machine code, allowing for easier coding. Her vision was to enable more people to write software and to reduce the time required for programming, ultimately advancing the field of computer science.
What would the bootstrap do?
"Bootstrapping" is long for "booting", which is simply a technique by which a simple computer program activates a more complicated system of programs.
What is the difference between compiler and profiler?
A profiler examines source code or machine code to determine memory and performance complexities, usage of certain instructions and the frequency and duration of function calls. Profilers are used as an aid to optimising code during the performance engineering phase of development. A compiler processes source code to produce machine code. A compiler also optimises the emitted code through inline expansion, compile-time computations, tail-call recursions, code re-ordering and so on. Compiler optimisations are well-defined, but the analysis is primitive compared to profiling which performs more extensive and time-consuming analysis of the code.
What is the assembler of java c plus plus c and asp.net?
There is no such thing. An "assembler" is a program that converts assembly language code, into machine language. Other programming languages have a "compiler", which is more or less equivalent.
What is source code c?
"Source code", in a programming language, refers to the original program, as written by a programmer (and more or less readable by humans); the version of the program before it is converted into machine language by the compiler.
