Building SPIR-V binaries by hand is error-prone and verbose; this Skill provides a complete reference for the glslang SpvBuilder API so you can programmatically generate types, instructions, control flow, and decorations for shader modules inside LuisaCompute.

Create a spv::Builder with a target SPIR-V version, set the source language and memory model, add required capabilities, then emit types, functions, and instructions. Finally call builder.dump() to serialize the module into a word vector.
Use spv::Builder::If with makeBeginElse and makeEndIf for selections, and makeNewLoop with createLoopMerge, createConditionalBranch, and closeLoop for loops. These helpers maintain valid structured control flow automatically.
Yes, the builder provides makeAccelerationStructureType, makeRayQueryType, makeHitObjectEXTType, and makeCooperativeMatrixTypeKHR. You must add the corresponding extensions such as SPV_KHR_ray_tracing before use.
OpSwitch case literals are sized by the selector's OpTypeInt width, not a fixed word count. A 64-bit selector uses two literal words per case, so parsers must consume ceil(bit_width/32) words before reading each target label.
Invalid topology arises when an outer selection merge is also an inner arm branching to the inner merge, causing inReadableOrder traversal to misclassify blocks. Fix the producer's physical control-flow plan by rotating merge declarations rather than patching serialization.
