Bryan Cain	ae6eba3e32	glsl: add ir_emit_vertex and ir_end_primitive instruction types ... These correspond to the EmitVertex and EndPrimitive functions in GLSL. v2 (Paul Berry <stereotype441@gmail.com>): Add stub implementations of new pure visitor functions to i965's vec4_visitor and fs_visitor classes. v3 (Paul Berry <stereotype441@gmail.com>): Rename classes to be more consistent with the names used in the GL spec.

Kenneth Graunke	807e967c61	glsl: Use ir_rvalue to represent generic error_type values. ... 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.

Luca Barbieri	55adbebc62	glsl: add ir_control_flow_visitor ... This is just a subclass of ir_visitor with empty implementations of all the visit methods for non-control flow nodes. Used to avoid duplicating that in ir_visitor subclasses. ir_hierarchical_visitor is another way to solve this, but is less natural for some applications.	2010-09-13 13:03:09 -07:00
