A Symbol consists of a common part (in class Symbol) containing name, owner, attributes. Information for a specific kind of symbol is in a variant containing one of the *Details classes. So the kind of symbol is determined by the type of details class stored in the details_ variant. For scopes there is a single Scope class with an enum indicating the kind. So far there isn't a need for extra kind-specific details as with Symbols but that could change. Symbols defined in a Scope are stored there in a simple map. resolve-names.cc is a partial implementation of a parse-tree walker that resolves names to Symbols. Currently is only handles functions (which introduce a new Scope) and entity-decls. The test-type executable was reused as a driver for this to avoid the need for a new one. Sample output is below. When each "end function" is encountered the scope is dumped, which shows the symbols defined in it. $ cat a.f90 pure integer(8) function foo(arg1, arg2) result(res) integer :: arg1 real :: arg2 contains function bar(arg1) real :: bar real :: arg1 end function end function $ Debug/tools/f18/test-type a.f90 Subprogram scope: 0 children arg1: Entity type: REAL bar: Entity type: REAL Subprogram scope: 1 children arg1: Entity type: INTEGER arg2: Entity type: REAL bar: Subprogram (arg1) foo: Subprogram (arg1, arg2) result(res) res: Entity type: INTEGER(8) Original-commit: flang-compiler/f18@1cd2fbc04d Reviewed-on: https://github.com/flang-compiler/f18/pull/30 Tree-same-pre-rewrite: false |
