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 of the ROM was written in Z80 machine code, but some was also coded in Forth.

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

Some Forth systems produce direct-threaded code.

Some exotic instruction sets do not have an opcode field ( such as Transport Triggered Architectures ( TTA ) or the Forth virtual machine ), only operand ( s ).

Some tried to cross the River Forth where most drowned in the attempt.

Some characters are allusions to persons involved in the construction of Forth Railway Bridge: Chief Engineer Arrol refers to the proprietor of the construction company, Sir William Arrol, whilst Engineers Baker and Fowler represent the two principal designers of the bridge, Sir Benjamin Baker and Sir John Fowler.

Some guns pointed out into the Forth to keep English warships at a distance.

Bunyan countered Burrough's pamphlet with A Vindication of Some Gospel Truths Opened, which Burrough answered with Truth ( the Strongest of All ) Witnessed Forth.

Some of the stone from the former castle was used to help build the caissons of the Forth Bridge.

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 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 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 efficiency-minded compilers employ a hybrid approach in which the activation records for a function are allocated from the stack if the compiler is able to deduce, through static program analysis, that the function creates no upwards funargs.

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 flowers are functionally staminate ( where a pistil may be present but has no ovules capable of being fertilized ) while others are functionally pistillate ( where stamens are present but their anthers do not produce viable pollen ).

Some of the plants are herbs that produce enough scent to possibly dilute the odours of nearby plants, or the pheromones emitted by insects that find those plants, which would otherwise attract more pests.

Some astronomers endeavoured to explain this by parallax, but these attempts were futile, for the motion was at variance with that which parallax would produce.

Some looms have roller bars that allow the weaver to produce pieces that are longer than the loom.

Some species of mold produce alpha-galactosidase, an anti-oligosaccharide enzyme, which humans can take to facilitate digestion of oligosaccharides in the small intestine.

Some examples are the designing of organisms to produce antibiotics, and the engineering of genetic cures through genetic manipulation.

Some types of instructions manipulate the program counter rather than directly produce result data.

Some chemical reactions, like those used to produce the active ingredients for the popular statin drugs, must occur at low temperatures of approximately − 100 ° C ( about-148 ° F ).

Some dyes can be precipitated with an inert salt to produce a lake pigment, and based on the salt used they could be aluminum lake, calcium lake or barium lake pigments.

Some makers produce smaller timbales 8 " or 10 " in diameter more suited to drum kit usage, see Timbales # Non-traditional use.

Some engines convert heat from noncombustive processes into mechanical work, for example a nuclear power plant uses the heat from the nuclear reaction to produce steam and drive a steam engine, or a gas turbine in a rocket engine may be driven by decomposing hydrogen peroxide.

Some enterobacteria produce endotoxins.

Some members of the Enterobacteriaceae family produce a systemic infection into the blood stream when all the dead bacterial cells release their endotoxins.

Some methods keep it crispy while other methods produce sauerkraut.

Some LABs produce the antimicrobial nisin which is a particularly effective preservative.

Some preschool ( ages 3 – 4 ) intervention programs like " Head Start " do not produce lasting changes of IQ, although they may confer other benefits.

Some guitar players have used LEDs in the fretboard to produce unique lighting effects onstage.

Some argue this as evidence of superiority of capitalism, since the peasants were generally able to sell their produce.

Some writers restrict the meaning of endothermy to mechanisms that directly raise the animal's metabolic rate in order to produce heat.

Some companies and independent smiths outside of Japan produce katana as well, with varying levels of quality.

Some species produce coloured bracts at the apices.

Some lasers do not use an optical cavity, but instead rely on very high optical gain to produce significant amplified spontaneous emission ( ASE ) without needing feedback of the light back into the gain medium.

Some of these instruments produce a virtual image when applied to the human eye ; others produce a real image which can be captured on photographic film or an optical sensor, or can be viewed on a screen.
