Lisp (historically LISP, an abbreviation of "list processing") is a family of programming languages with a long history and a distinctive, fully parenthesized prefix notation. [3] Originally specified in the late 1950s, it is the second-oldest high-level programming language still in common use, after Fortran.
Interprocedural optimization. Interprocedural optimization (IPO) is a collection of compiler techniques used in computer programming to improve performance in programs containing many frequently used functions of small or medium length. IPO differs from other compiler optimizations by analyzing the entire program as opposed to a single function ...
This article describes the calling conventions used when programming x86 architecture microprocessors. Calling conventions describe the interface of called code: The order in which atomic (scalar) parameters, or individual parts of a complex parameter, are allocated. How parameters are passed (pushed on the stack, placed in registers, or a mix ...
Reorder operations to allow multiple computations to happen in parallel, either at the instruction, memory, or thread level. More precise information is better. The more precise the information the compiler has, the better it can employ any or all of these optimization techniques. Runtime metrics can help.
process.h. process.h is a C header file which contains function declarations and macros used in working with threads and processes. Most C compilers that target DOS, Windows 3.1x, Win32, OS/2, Novell NetWare or DOS extenders supply this header and the library functions in their C library. Neither the header file nor most of the functions are ...
List scheduling is a greedy algorithm for Identical-machines scheduling. The input to this algorithm is a list of jobs that should be executed on a set of m machines. The list is ordered in a fixed order, which can be determined e.g. by the priority of executing the jobs, or by their order of arrival. The algorithm repeatedly executes the ...
The C preprocessor is the macro preprocessor for several computer programming languages, such as C, Objective-C, C++, and a variety of Fortran languages. The preprocessor provides inclusion of header files, macro expansions, conditional compilation, and line control. The language of preprocessor directives is only weakly related to the grammar ...
Procedural programming is a programming paradigm, classified as imperative programming, [1] that involves implementing the behavior of a computer program as procedures (a.k.a. functions, subroutines) that call each other. The resulting program is a series of steps that forms a hierarchy of calls to its constituent procedures.
