- The SPIR-V spec generator has changed how it represents optional
operands. Now it tracks a separate boolean flag indicating optionality.
However, SPIRV-Tools still wants to represent both operand class
and optionality in the same enums space (SPV_OPERAND_TYPE_*).
So there's extra work in the patch.
- In the spec generator, OperandImage is now OperandImageOperands.
This affects enum translation in opcode.cpp.
- In the spec generator, image operands are explicitly followed by
Id, and VariableIds. However, SPIRV-Tools uses the bits set
in the image operand bitmask to control the number and meaning
of the Ids that follow. So in writing the opcode.inc syntax
table, drop all operands after OperandImageOperands.
- Some enums are now more explicitly represented in the generated
opcode.inc:
- AccessQualifier (e.g. on OpTypeImage), in both required and
optional flavours.
- MemoryAccess (e.g. on loads and stores)
- Add SPV_OPERAND_TYPE_OPTIONAL_ACCESS_QUALIFIER
- Add tests for the optional AccessQualifier operand on OpTypeImage.
- Update the AccessQualifier test for OpTypeImage so it's a round
trip test through the disassembler as well.
