Hi, I was trying to convert the gcc C-Gimple form to the internal AST representation used in our research compiler. I was able to transform most of the nodes of the GIMPLE tree but was not able to find out a way to retrieve the global declarations from the GIMPLE tree. For example is there a way to get the declarations of structs and unions etc that are there at the translation unit level and declared at the function scope?
One place I figured, to get this information is when the C-file is being parsed by the parser. However this requires changing the gcc front end in a big way which we wanted to avoid. I was wondering if anyone can help me figure out a way to retrieve this information from the GIMPLE tree itself. Thanks a lot. Regards, Mayank
