We need two internal global variables for language: user_set_lang for storing user-specified language, auto_lang for storing parser detected language. Our only report errors that are incompatible.
Now we have three APIs:
setLang: set the user_set_lang variable to the language user wants to parse in the future call to parseOpenMP
getLang: return the value of the user_set_lang variable
parseOpenMP: check the language for the string to be parsed (we can only detect C/C++ and Fortran, we cannot differentiate C and C++), if it is not compatible (C and C++ are compatible) with the user_set_lang that is already set, report error and return. If user_set_lang is not set, parser will use the detected language (stored in auto_lang variable) for the parsing and set the directive->lang field. In this case, auto_lang will be set at begining as Lang_C and then will be reset as Lang_C++. The directive->lang will be either user_set_lang or the detected 'auto_lang'.
For linear clause, detecting language needs to be done at the beginning for C/Fortran and then in the middle of parsing as well since only some modifier are allowed for C++. So if C++ modifier is parsed, parser needs to set auto_lang to C++ if the current auto_lang is not lang_fortran, parser also needs to check whether user_set_langis set and if so, compare it withauto_lang`.
