  2. Incremental compiler - Wikipedia

    en.wikipedia.org/wiki/Incremental_compiler

    The Eclipse platform has included an incremental compiler for Java as a part of the Java Development Tools project [6] The Gradle build tool has supported incremental Java compilation since version 2.1. [7] IBM VisualAge C++ compiler 4.0; Embarcadero Delphi; The .NET Compiler Platform (C# and Visual Basic .NET) Rust [8] Go [9] Forth; Ceylon ...

  3. Value numbering - Wikipedia

    en.wikipedia.org/wiki/Value_numbering

    In the following example, a and b could be assigned the same number: a ← 1 + 2 b ← 2 + 1 This issue can easily be resolved either by assigning the same number to both cases (i.e. a + b and b + a are both recorded with the same number) or by sorting the operands before checking for equivalents.

  4. C99 - Wikipedia

    en.wikipedia.org/wiki/C99

    Cover of the C99 standards document. C99 (previously C9X, formally ISO/IEC 9899:1999) is a past version of the C programming language open standard. [1] It extends the previous version with new features for the language and the standard library, and helps implementations make better use of available computer hardware, such as IEEE 754-1985 floating-point arithmetic, and compiler technology.

  5. Name mangling - Wikipedia

    en.wikipedia.org/wiki/Name_mangling

    32-bit compilers emit, respectively: _f _g@4 @h@4 In the stdcall and fastcall mangling schemes, the function is encoded as _name@X and @name@X respectively, where X is the number of bytes, in decimal, of the argument(s) in the parameter list (including those passed in registers, for fastcall).

  6. Line number - Wikipedia

    en.wikipedia.org/wiki/Line_number

    Unlike FORTRAN before it or BASIC after it, JOSS required line numbers to be fixed-point numbers consisting of a pair of two-digit integers separated by a period (e.g., 1.1). The portion of the line number to the left of the period is known as the "page" or "part", while the portion to the right is known as the "line"; for example, the line ...

  7. C11 (C standard revision) - Wikipedia

    en.wikipedia.org/wiki/C11_(C_standard_revision)

    More macros for querying the characteristics of floating-point types, concerning subnormal floating-point numbers and the number of decimal digits the type is able to store. Anonymous structures and unions, useful when unions and structures are nested, e.g. in struct T {int tag; union {float x; int n;};};.

  8. Register allocation - Wikipedia

    en.wikipedia.org/wiki/Register_allocation

    In compiler optimization, register allocation is the process of assigning local automatic variables and expression results to a limited number of processor registers. Register allocation can happen over a basic block ( local register allocation ), over a whole function/ procedure ( global register allocation ), or across function boundaries ...

  9. C preprocessor - Wikipedia

    en.wikipedia.org/wiki/C_preprocessor

    The "traditional mode" (acting like a pre-ISO C preprocessor) is generally more permissive and better suited for such use. [16] Some modern compilers such as the GNU C Compiler provide preprocessing as a feature of the compiler; not as a separate tool.
