When code generation occurs at runtime, as in just-in-time compilation (JIT), it is important that the entire process be efficient with respect to space and time. For example, when regular expressions are interpreted and used to generate code at runtime, a non-deterministic finite-state machine is often generated instead of a deterministic one, because usually the former can be created more ...
If a template uses {{Infobox person/weight|{{{weight}}}|kg-stlb=yes}}, then an article using that template with an input in kg will display two conversions: lb followed by st/lb (default is one conversion to lb):
To explain, the lefthand T is a C compiler written in C that produces machine code. The righthand T is a C compiler written in machine code that also produces machine code. The diagram illustrates that this can be used to bootstrap the left T by using it to compile the compiler written in C. In computing, tombstone diagrams (or T-diagrams ...
SWIG will compile the interface file and generate code in regular C/C++ and the target programming language. SWIG will generate conversion code for functions with simple arguments; conversion code for complex types of arguments must be written by the programmer.
The name "compiler" is primarily used for programs that translate source code from a high-level programming language to a low-level programming language (e.g. assembly language, object code, or machine code) to create an executable program. There are many different types of compilers which produce output in different useful forms.
Hommel would extend his C compiler to a full C++ implementation while disentangling it from the code generation stage. McEnerney would write a new PPC code generator that would be driven by Hommel's compiler. Hommel's existing 68K code generator would be used for that platform, slightly modified to support Pascal as well.
Users invoke a language-specific driver program (gcc for C, g++ for C++, etc.), which interprets command arguments, calls the actual compiler, runs the assembler on the output, and then optionally runs the linker to produce a complete executable binary. Each of the language compilers is a separate program that reads source code and outputs ...
Compiler Description Language (CDL) is a programming language based on affix grammars. It is very similar to Backus–Naur form (BNF) notation. It was designed for the development of compilers .
