--- Comment #1 from Ian Romanick <i...@freedesktop.org> ---
At least per the GLSL 1.50 specification, this test enforces NON-conformance!
The grammar makes it quite clear that
in struct { ... } foo;
declares a shader input "foo" that is an anonymous structure. Here are the
relevant bits of the grammar (with some omissions for clarity):
single_declaration:
...
fully_specified_type IDENTIFIER
...
fully_specified_type:
type_specifier
type_qualifier type_specifier
type_qualifier:
storage_qualifier
...
storage_qualifier:
...
IN
...
type_specifier:
type_specifier_no_prec
precision_qualifier type_specifier_no_prec
type_specifier_no_prec:
type_specifier_nonarray
...
type_specifier_nonarray:
VOID
FLOAT
INT
...
struct_specifier
TYPE_NAME
struct_specifier:
...
STRUCT LEFT_BRACE struct_declaration_list RIGHT_BRACE
Neither section 4.3.4 (Inputs) nor section 4.3.7 (Interface Blocks) add any
limitations that I can see. I'll dig through later specs to see if this
changed.
