You need to walk the body of the function looking for defining stmts. Note the VAR_DECL might be in SSA form in which case you can also walk all SSA names and check those whose SSA_NAME_VAR is the specific VAR_DECL. But then SSA names can "lose" their associated decks so when a variable is in SSA form the set of original assignments cannot always be recovered easily. Richard. > Thanks, > > Pierrick >
