Use opcode operand definitions from SPIR-V specification generator. The assembler and disassembler now use a dynamically adjusted sequence of expected operand types. (Internally, it is a deque, for readability.) Both parsers repeatedly pull an expected operand type from the left of this pattern list, and try to match the next input token against it. The expected pattern is adjusted during the parse to accommodate: - an extended instruction's expected operands, depending on the extended instruction's index. - when an operand itself has operands - to handle sequences of zero or more operands, or pairs of operands. These are expanded lazily during the parse. Adds spv::OperandClass from the SPIR-V specification generator. Modifies spv_operand_desc_t: - adds hasResult, hasType, and operandClass array to the opcode description type. - "wordCount" is replaced with "numTypes", which counts the number of entries in operandTypes. And each of those describes a *logical* operand, including the type id for the instruction, and the result id for the instruction. A logical operand could be variable-width, such as a literal string. Adds opcode.inc, an automatically-generated table of operation descriptions, with one line to describe each core instruction. Externally, we have modified the SPIR-V spec doc generator to emit this file. (We have hacked this copy to use the old semantics for OpLine.) Inside the assembler, parsing an operand may fail with new error code SPV_FAIL_MATCH. For an optional operand, this is not fatal, but should trigger backtracking at a higher level. The spvTextIsStartOfNewInst checks the case of the third letter of what might be an opcode. So now, "OpenCL" does not look like an opcode name. In assembly, the EntryPoint name field is mandatory, but can be an empty string. Adjust tests for changes to: - OpSampedImage - OpTypeSampler

Use opcode operand definitions from SPIR-V specification generator. The assembler and disassembler now use a dynamically adjusted sequence of expected operand types. (Internally, it is a deque, for readability.) Both parsers repeatedly pull an expected operand type from the left of this pattern list, and try to match the next input token against it. The expected pattern is adjusted during the parse to accommodate: - an extended instruction's expected operands, depending on the extended instruction's index. - when an operand itself has operands - to handle sequences of zero or more operands, or pairs of operands. These are expanded lazily during the parse. Adds spv::OperandClass from the SPIR-V specification generator. Modifies spv_operand_desc_t: - adds hasResult, hasType, and operandClass array to the opcode description type. - "wordCount" is replaced with "numTypes", which counts the number of entries in operandTypes. And each of those describes a *logical* operand, including the type id for the instruction, and the result id for the instruction. A logical operand could be variable-width, such as a literal string. Adds opcode.inc, an automatically-generated table of operation descriptions, with one line to describe each core instruction. Externally, we have modified the SPIR-V spec doc generator to emit this file. (We have hacked this copy to use the old semantics for OpLine.) Inside the assembler, parsing an operand may fail with new error code SPV_FAIL_MATCH. For an optional operand, this is not fatal, but should trigger backtracking at a higher level. The spvTextIsStartOfNewInst checks the case of the third letter of what might be an opcode. So now, "OpenCL" does not look like an opcode name. In assembly, the EntryPoint name field is mandatory, but can be an empty string. Adjust tests for changes to: - OpSampedImage - OpTypeSampler
