백엔드

export 27개

백엔드가 지켜야 하는 계약과 기능 모델, 그리고 대상마다 내장 함수를 어떤 이름으로 낼지 정하는 레지스트리입니다.

시그니처, 설명, 예제는 커밋 26de7be8의 컴파일러 소스에서 그대로 가져온 영어 원문입니다.

ATOMIC_INTRINSICS 상수

The atomic builtins, with the arity and result of each: atomicLoad takes the location alone and returns its value; atomicStore takes a value and returns nothing; the eight read-modify-write forms take a value and return the value the location held before the update.

Backend 인터페이스

The contract a target writer implements.

BARRIER_INTRINSICS 상수

The barriers: workgroupBarrier() and storageBarrier(), statements with no value that every invocation of a workgroup reaches before any runs on.

barrierOutsideDispatch 함수

The error every CPU path throws when a barrier runs outside a dispatch: a barrier waits for the other invocations of the workgroup, and one invocation run alone, by a direct fns call or by a debug session, has none.

Capabilities 클래스

The set of capabilities a backend supports, built from its capProfile with Capabilities.fromProfile.

capabilityMatrix 함수

Report which backend can spell which capability, as one row per capability with a support class per backend.

CapabilityRow 인터페이스

One row of the capability matrix: a capability and how each backend supports it.

CapProfile 타입

A backend's capability table, and the single authority for what its target supports.

CapSupport 인터페이스

What one capability costs on one target: the row of a backend's capProfile.

CapSupportKind 타입

How one backend supports one capability. - 'native': supported, with nothing to emit and nothing for the host to turn on. - 'directive': supported, and the emitted source declares it.

DERIVATIVE_INTRINSICS 상수

The intrinsics whose value is a difference between neighbouring invocations, so WGSL requires uniform control flow at the call: the derivatives themselves and every sampling form that derives its level of detail implicitly.

hostFeaturesFor 함수

Translate neutral capability ids into the feature strings one target's host has to activate before it creates a pipeline.

INTRINSIC_BINDING_REFS 상수

The binding names an intrinsic's emitted text reads directly, keyed by intrinsic id, for the intrinsics whose spelling names a binding with no argument carrying it.

INTRINSIC_HELPERS 상수

The helper functions an intrinsic's GLSL spelling calls, keyed by intrinsic id.

intrinsicNeedsAtomArgs 함수

Returns true when name's spelling splices an argument into a position that binds tighter than a plain argument slot, such as an operand of an inlined operator or the base of a .field postfix.

INTRINSICS 상수

The spelling of each builtin id on each target, keyed by id.

IntrinsicTarget 타입

The emit target that spellIntrinsic and the INTRINSICS table spell for: 'wgsl' or 'glsl'.

isAtomicIntrinsic 함수

Whether name is one of the ATOMIC_INTRINSICS.

isBarrierIntrinsic 함수

Whether name is one of the BARRIER_INTRINSICS.

isKnownIntrinsic 함수

Returns true when name is a builtin the registry can spell on every target: either an id with an INTRINSICS entry or a member of PORTABLE_INTRINSICS.

PACKED_4X8_IDS 상수

The eight packed 4x8 integer builtins.

PACKED_4X8_LANGUAGE_FEATURE 상수

The WGSL language feature a module using PACKED_4X8_IDS depends on, as navigator.gpu.wgslLanguageFeatures names it.

PORTABLE_INTRINSICS 상수

The builtin ids that spell identically on both targets, such as sin, dot and clamp.

PRE_EMIT_INTRINSICS 상수

The builtin ids that fp64Lower rewrites away before any backend runs: 'f64', 'f64FromParts' and 'f64Parts'.

spellIntrinsic 함수

Spells a call for one target.

TEXTURE_GATHER_IDS 상수

The neutral ids a textureGather / textureGatherCompare call lowers to, one per WGSL argument structure.

UnsupportedFeatureError 클래스

Thrown when a module needs a feature the target backend does not support, with code SD0030.
