Detailed Description

A SPIR-V module serializer.

A SPIR-V binary module is a single linear stream of instructions; each instruction is composed of 32-bit words with the layout:

| <word-count>|<opcode> | <operand> | <operand> | ... | | <---— word ----—> | <– word --> | <– word --> | ... |

For the first word, the 16 high-order bits are the word count of the instruction, the 16 low-order bits are the opcode enumerant. The instructions then belong to different sections, which must be laid out in the particular order as specified in "2.4 Logical Layout of a Module" of the SPIR-V spec.
