Some software providers also produced compilers for BASIC, and other languages, to produce binary ( or " machine ") code which would run many times faster and make better use of the small system RAM.

Some compilers, such as gcc, add extra keywords for a programmer to explicitly mark external functions as pure, to enable such optimizations.

Some Forth implementations ( usually early versions or those written to be extremely portable ) compile threaded code, but many implementations today generate optimized machine code like other language compilers.

Some aspects attributed to the first RISC-labeled designs around 1975 include the observations that the memory-restricted compilers of the time were often unable to take advantage of features intended to facilitate manual assembly coding, and that complex addressing modes take many cycles to perform due to the required additional memory accesses.

Some Forth compilers compile Forth programs into direct-threaded code, while others make indirect-threaded code.

Some Forth compilers produce token threaded code.

Some programmers consider the " p-code " generated by some Pascal compilers, as well as the bytecodes used by. NET, Java, BASIC and some C compilers to be token-threading.

Some compilers in this category provide special constructs or extensions to allow programmers to directly specify operations to be performed in parallel ( e. g., DO FOR ALL statements in the version of FORTRAN used on the ILLIAC IV, which was a SIMD multiprocessing supercomputer ).

Some systems, called dynamic translators, or " just-in-time " ( JIT ) compilers, translate bytecode into machine language as necessary at runtime: this makes the virtual machine unportable, but doesn't lose the portability of the bytecode itself.

:; Machine code generation: Some compilers compile source code directly into machine code.

Some, but not all, optimizations can nowadays be performed by optimizing compilers. is often easier to optimize at this stage, and profiling may reveal unexpected performance problems that would not have been addressed by premature optimization.

Some compilers support an option to turn recognition of trigraphs off, or disable trigraphs by default and require an option to turn them on.

Some languages allow, some require, compilers to provide coercion.

Some compilers and lint-like tools flag occurrences of singleton variables.

Some languages and compilers may provide sufficient facilities to implement functions which address both the compiler reordering and machine reordering issues.

Some older compilers allow one only to specialize either all or none of the template's parameters.

Some historians believe that he was one of the compilers of the Chronicles of Nikon.

Some architectures, compilers, or optimization cases store one link for each enclosing level ( not just the immediately enclosing ), so that deeply nested routines that access shallow data do not have to traverse several links ; this strategy is often called a display.

Some historical computers, such as the Burroughs large systems, had special " display registers " to support nested functions while compilers for most modern machines ( such as the ubiquitous x86 ) simply reserve a few words on the stack for the pointers, as needed.

Some early C compilers had the feature, now seen as an annoyance, of generating a warning on any function call that did not use the function's returned value.

Some compilers require that the letters of the joey word not be consecutive within the kangaroo word, or that the kangaroo and joey words must be etymologically unrelated.

Some of the Columbia and Snake River dams employ fish ladders, which are effective to varying degrees at allowing these fish to travel upstream.

Some libraries that employ content-control software allow the software to be deactivated on a case-by-case basis on application to a librarian ; libraries that are subject to CIPA are required to have a policy that allows adults to request that the filter be disabled without having to explain the reason for their request.

Some contemporary philosophers and scientists ( e. g. David Deutsch in The Fabric of Reality ) employ virtual reality in various thought experiments.

Some such units employ batteries that can provide power for several hours in case of external power interruption ( e. g., see the EMC Symmetrix ) and thus maintain the content of the volatile storage parts intact.

Some non-alphabetic scripts also employ symbols that function essentially as diacritics.

Some are attempting to counter this technique, however, with a number of systems which offer diverse views and information which highlights the manipulative and dishonest methods that advertisers employ.

Some such units employ batteries that can provide power for several hours in case of external power interruption ( e. g., see the EMC Symmetrix ) and thus maintain the content of the volatile storage parts intact.

Some churches founded independently of these lineages also employ this form of church governance.

Some musicians who use rackmounted effects or laptops employ a MIDI controller pedalboard or armband remote controls to trigger sound samples, switch between different effects or control effect settings.

Some vehicles, such as the French VBCI, employ infra-red jamming flare dispensers.

Some cultures also employ matrilineal succession only passing property along the female line.

Some ancient societies and most modern states employ partible inheritance, under which every child inherits ( usually equally ).

Some makers instead employ " x-bracing ," which is two tone bars mortised together to form an X.

" Some institutions ( such as the Harvard Business School ) use that name while others ( such as the Yale School of Management ) employ the more inclusive term " management.

Some writers on English grammar employ the term subjective case instead of nominative to draw attention to the differences between the " standard " generic nominative and the way it is used in English.

Some musicals, such as Tommy ( 1969 ) and Jesus Christ Superstar ( 1971 ), Les Misérables ( 1980 ), Rent ( 1996 ) and Spring Awakening ( 2006 ), employ various operatic conventions, such as through composition, recitative instead of dialogue, and leitmotifs.

Some jurisdictions allow Physical Therapists to employ technicians or aides to perform designated routine tasks related to physical therapy under the direct supervision of a Physical Therapist.

Some pawnbrokers have trained in identification of gems, or employ a specialist to assess jewelry.

Some teams employ a strategy which involves the use of more than one quarterback during the course of a game.

Some large transformers employ electric-operated fans or pumps for forced-air or forced-oil cooling or heat exchanger-based water-cooling.

Some ( especially at the college level ) still employ the tall wool-lined shako or much larger bearskin ( both often derisively referred to as a " Q-Tip hat ").

Some sea cucumbers employ a similar strategy, hitching lifts by attaching to the sides of fish.

Some animals, such as the kangaroo, employ jumping ( commonly called hopping in this instance ) as their primary form of locomotion, while others, such as frogs, use it only as a means to escape predators.

Some inventions in visual art employ prior developments in science or technology.

Some walkie-talkies that employ frequency-hopping spread spectrum technology have been developed for unlicensed use on the 900 MHz band.
