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

hex_float: Use max_digits10 for the float precision CPPreference.com has this description of digits10: “The value of std::numeric_limits<T>::digits10 is the number of base-10 digits that can be represented by the type T without change, that is, any number with this many significant decimal digits can be converted to a value of type T and back to decimal form, without change due to rounding or overflow.” This means that any number with this many digits can be represented accurately in the corresponding type. A change in any digit in a number after that may or may not cause it a different bitwise representation. Therefore this isn’t necessarily enough precision to accurately represent the value in text. Instead we need max_digits10 which has the following description: “The value of std::numeric_limits<T>::max_digits10 is the number of base-10 digits that are necessary to uniquely represent all distinct values of the type T, such as necessary for serialization/deserialization to text.” The patch includes a test case in hex_float_test which tries to do a round-robin conversion of a number that requires more than 6 decimal places to be accurately represented. This would fail without the patch. Sadly this also breaks a bunch of other tests. Some of the tests in hex_float_test use ldexp and then compare it with a value which is not the same as the one returned by ldexp but instead is the value rounded to 6 decimals. Others use values that are not evenly representable as a binary floating fraction but then happened to generate the same value when rounded to 6 decimals. Where the actual value didn’t seem to matter these have been changed with different values that can be represented as a binary fraction.
