* glsl: add ir_emit_vertex and ir_end_primitive instruction typesBryan Cain2013-08-011-0/+18
| | | | | | | | | | | | | | These correspond to the EmitVertex and EndPrimitive functions in GLSL. v2 (Paul Berry <[email protected]>): Add stub implementations of new pure visitor functions to i965's vec4_visitor and fs_visitor classes. v3 (Paul Berry <[email protected]>): Rename classes to be more consistent with the names used in the GL spec.

* glsl: Use ir_rvalue to represent generic error_type values.Kenneth Graunke2012-04-021-0/+9
| | | | | | | | | | | | | | | | | | | | | | Currently, ir_call can be used as either a statement (for void functions) or a value (for non-void functions). This is rather awkward, as it's the only class that can be used in both forms. A number of places use ir_call::get_error_instruction() to construct a generic value of error_type. If ir_call is to become a statement, it can no longer serve this purpose. Unfortunately, none of our classes are particularly well suited for this, and creating a new one would be rather aggrandizing. So, this patch introduces ir_rvalue::error_value(), a static method that creates an instance of the base class, ir_rvalue. This has the nice property that you can't accidentally try and access uninitialized fields (as it doesn't have any). The downside is that the base class is no longer abstract.
