ORACLE_GPU_STUB_NAMES
상수, CPU 오라클 분류
The names of every GPU-only intrinsic the CPU backends cannot genuinely evaluate, as a read-only set: textureSample, textureSampleLevel, textureSampleBias, textureSampleGrad, textureLoad, their 2d-array forms, the depth comparisons, textureDimensions, textureNumLayers, and the derivatives fwidth, dpdx and dpdy.

구문
const ORACLE_GPU_STUB_NAMES: ReadonlySet<string>설명
A texture read needs the GPU’s sampler and texture memory, and a derivative
needs neighbouring fragments; a CPU run of a single invocation has neither. Calling
one of these from a module compiled with compileModule or
compileModuleJs throws, unless the module was compiled with
{ gpuStubs: true }; then it returns a placeholder: [0, 0, 0, 1] for a texture
read, [1, 1] for textureDimensions, 1 for textureNumLayers and 0 for a
derivative. Meant for tests: the union of this set and ORACLE_BUILTIN_NAMES
should cover every intrinsic in INTRINSICS and PORTABLE_INTRINSICS,
so a test can assert that each intrinsic a shader can emit has either a CPU
implementation or a documented placeholder.
