We need to know how to generate correct SPIRV for cases like
OpConstant %int64 42 since the current parser will encode the 42 as a
32-bit value incorrectly.
This change is the first of a pair. This one tracks types, and makes
sure that OpConstant and OpSpecConstant are only ever called with
Integer or Float types, and OpSwitch is only called with integer
generating values.
Move the definition of spv_instruction_t to an internal
header file, since it now depends on C++ and is not
used by the external interface.
Use a std::vector<uint32_t> in spv_instruction_t
instead of a fixed size array.
Fixes dependencies among capabilities. (The table should store
the mask of capabilites, not the capability enum.)
Remove the old spot check test for capabilities of enums.
Currently it uses a union, a write to one field, and read from
another of a different type.
Moves the endianness-determining macro close to the variable
it references.
Adds a form of spvtest::MakeInstruction which takes two vectors
of operands. That leads to simpler test code.
We can clean up some other test code, in another CL.
Implement some outstanding feedback from
Ic29c5a4a8178a62a5a1acad13d02f19cc1307097:
- use "token" instead of "word" when referring to assembly text
- specify how the numbers are parsed
Add a test for negative numbers.
Operand class enum values not used in the syntax table:
- Image channel order: only used to describe a return value
- Image channel type: only used to describe a return value
- "Image operands": used to make a section in the spec
to describe values used to construct an optional image id,
but does not itself appear in the syntax table.
Removes some TODOs from opcode.cpp.
All uses of OptionalLiteral by the SPIR-V spec are used
for literal numbers.
Also rename:
- SPV_OPERAND_TYPE_OPTIONAL_LITERAL to
SPV_OPERAND_TYPE_OPTIONAL_LITERAL_NUMBER.
- SPV_OPERAND_TYPE_VARIABLE_LITERAL to
SPV_OPERAND_TYPE_VARIABLE_LITERAL_NUMBER.
- SPV_OPERAND_TYPE_VARIABLE_LITERAL_ID to
SPV_OPERAND_TYPE_VARIABLE_LITERAL_NUMBER_ID.
- SPV_OPERAND_TYPE_VARIABLE_ID_LITERAL to
SPV_OPERAND_TYPE_VARIABLE_ID_LITERAL_NUMBER.
- SPV_OPERAND_TYPE_LITERAL_IN_OPTIONAL_TUPLE to
SPV_OPERAND_TYPE_LITERAL_NUMBER_IN_OPTIONAL_TUPLE.
