Add glsl_type::get_base_type query
...
Retreives the glsl_type that corresponds to the base type of a numeric scalar /
vector / matrix type. So vec4 returns float, etc.

Begin processing constructors

Right now, reject constructors for samplers because the are illegal.

Disallow passing NULL for state to _mesa_glsl_error
...
The two places that were still passing NULL had a state pointer to
pass. Not passing it in these places prevented termination of
compilation of erroneous programs.

Add `void' type to table of available types
...
This will make void-01.glsl test fail, so I may regret this later.
However, this will make supporting functions that return void or
functions that have a void parameter list easier to handle.

Use glsl_symbol_table::name_declared_this_scope
...
Prevent most illegal name reuse.
2010-03-19 15:38:52 -07:00
ac4fdc255b
Add query to determine whether a name was declared at this scope
...
This will be used to prevent a variable and a function with the same
name from being declared. As a side effect, the calls to
add_{type,name,function} should never fail.
2010-03-19 15:37:01 -07:00
38395c1aad
Use separate namespaces for types, variables, and functions
...
This will allow types and their constructors to be easily stored in
the same symbol table. This does add a potential problem that a
shader could declare a variable and a function with the same name.
This appears to be forbidden by the GLSL spec.

Use glsl_symbol_table instead of using _mesa_symbol_table directly
2010-03-19 11:57:24 -07:00
82de85e264
Add a GLSL-specific facade to _mesa_symbol_table
...
This adds some type saftey and will enable elimination of a bunch of
type casts and other ugly crap in the code.

Don't track new type names during pass-1 parsing
...
This implementation was wrong anyway because it did not respect
scoping rules. This will need to be revisited soon. The most likely
result is that the grammar is going to need some significant re-work
to be able to use a IDENTIFIER in all the places where a TYPE_NAME is
currently used.

2010-03-15 14:31:48 -07:00
ed85a5dd4b
Add new constructors for ast_type_specifier
...
Add a constructor that uses an ast_struct_specifier and one that uses
a type name. This saves a (trivial) bit of code, but it also ensures
some of the class invariants (i.e., type_name != NULL) are met.
2010-03-15 14:28:17 -07:00
7f9d309743
Ensure that ast_type always has type_name set
...
For built-in types, type_name would be NULL. This ensures that
type_name is set even for the built-in types. This simplifies code in
a few places and centralizes the name setting code.

Change type of function_identifier to silence bison warning

When the implementation of function_call_header and
function_identifier were changed a few commits ago, the types of the
production changed. This just updates the types specified for the
productions to match reality.
