I am writing a GCC 9 Plugin to extract information about my C++ code. Imagine the following two code snippets: int i = ENUM_VAL; int j = static_cast<int>(1.5); Where ENUM_VAL is a value defined by an enum. The information I would like to extract via my gcc plugin is the enum type of ENUM_VAL and the type specified in the static_cast (so in this case int). What I have been trying so far is to latch onto the PRE_GENERICIZE pass to access the AST of functions and then walk through the tree until I arrive at the particular VAR_DECL. However, using the DECL_INITIAL macro on the VAR_DECL representing i and j returns an INTEGER_CST node, not a representing the enum value or the cast. Is there any way to access this information? Best regards
