설명

An operation used on f32 and on emulated f64 is two rows.

인스턴스 속성

op읽기 전용 string: The operation as the IR names it: a builtin id (sin, fma, textureSample), a binary operator (/, %, and for f64 every arithmetic operator), or a matrix product (mat * vec, vec * mat, mat * mat), which is a sum of products and not the component-wise *.
elem읽기 전용 'f32' | 'f64': The float the operation computes in: native f32, or emulated f64. An operation whose result is not a float is listed under the float it reads: a pack’s argument, and the coordinate of a textureGather on an integer texture, which is f32.
kind읽기 전용 DeterminismKind: Why the result may differ.
accuracy읽기 전용 string: The bound in words, from WGSL §15.7.4 for f32, from the emulation for f64, and from Rule 7.2’s tree for an order row.
count읽기 전용 number: How many times the operation occurs in the module.
where읽기 전용 readonly string[]: Where it occurs: the module constants, module variables and functions whose initializer or body holds it, by name, in declaration order, each once.
note선택 사항읽기 전용 string: What the GLSL ES 3.00 spelling does differently, when that matters.
