  2. GNU Compiler Collection - Wikipedia

    en.wikipedia.org/wiki/GNU_Compiler_Collection

    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 ...

  3. Reaching definition - Wikipedia

    en.wikipedia.org/wiki/Reaching_definition

    In compiler theory, a reaching definition for a given instruction is an earlier instruction whose target variable can reach (be assigned to) the given one without an intervening assignment. For example, in the following code:

    C23, formally ISO/IEC 9899:2024, is the current open standard for the C programming language, which supersedes C17 (standard ISO/IEC 9899:2018). [1] It was started in 2016 informally as C2x, [2] and was published on October 31, 2024. [3]

    C17, formally ISO/IEC 9899:2018, [1] is an open standard for the C programming language, prepared in 2017 and published in July 2018. It replaced C11 (standard ISO/IEC 9899:2011), [2] and is superseded by C23 (ISO/IEC 9899:2024) since October 2024. [3]

  7. Instruction selection - Wikipedia

    en.wikipedia.org/wiki/Instruction_selection

    In computer science, instruction selection is the stage of a compiler backend that transforms its middle-level intermediate representation (IR) into a low-level IR. In a typical compiler, instruction selection precedes both instruction scheduling and register allocation; hence its output IR has an infinite set of pseudo-registers (often known as temporaries) and may still be – and typically ...

  8. Compatibility of C and C++ - Wikipedia

    en.wikipedia.org/wiki/Compatibility_of_C_and_C++

    C++ began as a fork of an early, pre-standardized C, and was designed to be mostly source-and-link compatible with C compilers of the time. [ 1 ] [ 2 ] Due to this, development tools for the two languages (such as IDEs and compilers ) are often integrated into a single product, with the programmer able to specify C or C++ as their source language.

  9. Dependence analysis - Wikipedia

    en.wikipedia.org/wiki/Dependence_analysis

    In compiler theory, dependence analysis produces execution-order constraints between statements/instructions. Broadly speaking, a statement S2 depends on S1 if S1 must be executed before S2 . Broadly, there are two classes of dependencies-- control dependencies and data dependencies .
