Hi, again, I am a little unclear on VAR_DECL and DECL_EXPR. The impression I get from reading the docs is that when a variable is first declared in a function, a VAR_DECL should be created, possibly with DECL_INITIAL() set.
What's less clearly stated is what you use for variable references later in the code. I think you also use VAR_DECL for this purpose, but I'm not sure. Could someone clarify? If so, must it be the same tree node or does it just have to be another VAR_DECL with the same variable name? There is also DECL_EXPR representing local declarations, which appears to be related. How do these get used and would it even be used in a C-like language? Thanks, Jerry Quinn
