Hi, I am trying to understand what path is executed in GCC from parsing a C expression (in a global variable declaration) to the value in DECL_INITIAL. At the moment, I have annotated a tree during parsing. I have another debugging pass that looks for this tree in subsequent passes. The annotation persists if the tree is inside a function body. However, if the tree is in a global variable initialization (i.e., DECL_INITIAL), then I am unable to see the annotation even when placing the debugging pass at the beginning of passes.def.
Can someone provide a little bit of guidance? Thanks!
