Functions
void	mlir::spirv::appendModuleHeader (SmallVectorImpl< uint32_t > &header, spirv::Version version, uint32_t idBound)
	Appends a SPRI-V module header to header with the given version and idBound.
uint32_t	mlir::spirv::getPrefixedOpcode (uint32_t wordCount, spirv::Opcode opcode)
	Returns the word-count-prefixed opcode for an SPIR-V instruction.
void	mlir::spirv::encodeStringLiteralInto (SmallVectorImpl< uint32_t > &binary, StringRef literal)
	Encodes an SPIR-V literal string into the given binary vector.
StringRef	mlir::spirv::decodeStringLiteral (ArrayRef< uint32_t > words, unsigned &wordIndex)
	Decodes a string literal in words starting at wordIndex.
std::optional< spirv::Opcode >	mlir::spirv::getContinuationOpcode (spirv::Opcode parent)
	Returns the SPV_INTEL_long_composites continuation opcode that may follow parent, or std::nullopt if parent is not a splittable composite/struct op.
