An interpreter might well use the same lexical analyzer and parser as the compiler and then interpret the resulting abstract syntax tree. Example data type definitions for the latter, and a toy interpreter for syntax trees obtained from C expressions are shown in the box.
The purpose of assembly language, like other coding languages, is to make the programming process more user-friendly than programming in machine language. Assembler languages utilize mnemonic devices and symbolic addresses to differentiate between opcode, operands, and specific memory addresses.
C, viewed by some as a sort of portable assembly language, is frequently the target language of such compilers. For example, Cfront , the original compiler for C++ , used C as its target language. The C code generated by such a compiler is usually not intended to be readable and maintained by humans, so indent style and creating pretty C ...
Some assemblers are components of a compiler system for a high-level programming language and may have limited or no usable functionality outside of the compiler system. Some assemblers are hosted on the target processor and operating system, while other assemblers (cross-assemblers) may run under an unrelated operating system or processor.
Transpilers can be used to extend existing languages or to simplify compiler development by exploiting portable and well-optimized implementations of other languages (such as C). [ 2 ] Many combinations of interpretation and compilation are possible, and many modern programming language implementations include elements of both.
A source-to-source translator, source-to-source compiler (S2S compiler), transcompiler, or transpiler [1] [2] [3] is a type of translator that takes the source code of a program written in a programming language as its input and produces an equivalent source code in the same or a different programming language.
In computer programming, an inline assembler is a feature of some compilers that allows low-level code written in assembly language to be embedded within a program, among code that otherwise has been compiled from a higher-level language such as C or Ada.
In computer programming, a compile and go system; compile, load, and go system; assemble and go system; or load and go system [1] [2] [3] is a programming language processor in which the compilation, assembly, or link steps are not separated from program execution.
