qining 1773b95737 Pull out the number parsing logic ... Pull out the number parsing logic from AssemblyContext::binaryEncodeNumericLiteral() to utilities. The new utility function: `ParseAndEncodeNumber()` now accepts: * number text to parse * number type * a emit function, which is a function which will be called with each parsed uint32 word. * a pointer to std::string to be overwritten with error messages. (pass nullptr if expect no error message) and returns: * an enum result type to indicate the status Type/Structs moved to utility: * template<typename T> class ClampToZeroIfUnsignedType New type: * enum EncodeNumberStatus: success or error code * NumberType: hold the number type information for the number to be parsed. * several helper functions are also added for NumberType. Functions moved to utility: * Helpers: * template<typename T> checkRangeAndIfHexThenSignExtend() -> CheckRangeAndIfHex....() * Interfaces: * template<typename T> parseNumber() -> ParseNumber() * binaryEncodeIntegerLiteral() -> ParseAndEncodeIntegerNumber() * binaryEncodeFloatingPointLiteral() -> ParseAndEncodeFloatingPointNumber() * binaryEncodeNumericLiteral() -> ParseAndEncodeNumber() Tests added/moved to test/ParseNumber.cpp, including tests for: * ParseNumber(): This is moved from TextToBinary.cpp to ParseNumber.cpp * ParseAndEncodeIntegerNumber(): New added * ParseAndEncodeFloatingPointNumber(): New added * ParseAndEncodeNumber(): New added Note that the error messages are kept almost the same as before, but they may be inappropriate for an utility function. Those will be fixed in another CL.		2016-09-08 18:42:54 -04:00
