This works as expected:
typedef struct foo {
int bar;
} baz;
int
main ()
{
struct foo f;
return 0;
}
=>
(trans-unit
(decl (decl-spec-list
(stor-spec (typedef))
(type-spec
(struct-def
(ident "foo")
(field-list
(comp-decl
(decl-spec-list (type-spec (fixed-type "int")))
(comp-declr-list (comp-declr (ident "bar"))))))))
(init-declr-list (init-declr (ident "baz"))))
(fctn-defn
(decl-spec-list (type-spec (fixed-type "int")))
(ftn-declr (ident "main") (param-list))
(compd-stmt
(block-item-list
(decl (decl-spec-list
(type-spec (struct-ref (ident "foo"))))
(init-declr-list (init-declr (ident "f"))))
(return (p-expr (fixed "0")))))))
but typedef'ing struct foo to foo like so:
typedef struct foo {
int bar;
} foo;
int
main ()
{
struct foo f;
return 0;
}
gives unexpected parens when using it in main:
(trans-unit
(decl (decl-spec-list
(stor-spec (typedef))
(type-spec
(struct-def
(ident "foo")
(field-list
(comp-decl
(decl-spec-list (type-spec (fixed-type "int")))
(comp-declr-list (comp-declr (ident "bar"))))))))
(init-declr-list (init-declr (ident "foo"))))
(fctn-defn
(decl-spec-list (type-spec (fixed-type "int")))
(ftn-declr (ident "main") (param-list))
(compd-stmt
(block-item-list
(decl (decl-spec-list
(type-spec (struct-ref (ident ("foo")))))
(init-declr-list (init-declr (ident "f"))))
(return (p-expr (fixed "0")))))))
This bit: (struct-ref (ident ("foo")))
There seem to be more places where the extra parens occur.
Greetings,
