Ark Compiler, also known as ArkCompiler, is a unified compilation and runtime platform that supports joint compilation and running across programming languages and chip platforms, also operating systems of open-source OpenHarmony, Oniro OS, alongside proprietary HarmonyOS with single core system HarmonyOS NEXT included on native APP in Event-driven programming in a unified development ...
With Ark Compiler, it supports a variety of dynamic and static programming languages such as JS, TS, and ArkTS. It is the compilation and runtime base that enables OpenHarmony alongside HarmonyOS NEXT to run on multiple device forms such as smart devices, mobile phones, PCs, tablets, TVs, automobiles, and wearables.
It is most commonly associated with the act of compiling a higher-level programming language such as C or C++, or an intermediate representation such as Java bytecode or Common Intermediate Language (CIL) code, into native machine code so that the resulting binary file can execute natively, just like a standard native compiler.
Java bytecode is the instruction set of the Java virtual machine (JVM), the language to which Java and other JVM-compatible source code is compiled. [1] Each instruction is represented by a single byte, hence the name bytecode, making it a compact form of data.
In computer science, compile time (or compile-time) describes the time window during which a language's statements are converted into binary instructions for the processor to execute. [1] The term is used as an adjective to describe concepts related to the context of program compilation, as opposed to concepts related to the context of program ...
This example specifies a valid D function called "factorial" which would typically be evaluated at run time. The use of enum tells the compiler that the initializer for the variables must be computed at compile time. Note that the arguments to the function must be able to be resolved at compile time as well. [4]
Yacc (Yet Another Compiler-Compiler) is a computer program for the Unix operating system developed by Stephen C. Johnson.It is a lookahead left-to-right rightmost derivation (LALR) parser generator, generating a LALR parser (the part of a compiler that tries to make syntactic sense of the source code) based on a formal grammar, written in a notation similar to Backus–Naur form (BNF). [1]
Once they had improved the compiler to the point where it could compile its own source code, it was self-hosting. [2] The compiler as it exists on the standard compiler tape is a machine language program that was obtained by having the S-expression definition of the compiler work on itself through the interpreter. —
