[Mesa-dev] [PATCH 21/26] i965: Make fs_visitor::emit_urb_writes set EOT for TES as well.

[Kristian Høgsberg]

Kenneth Graunke <kenneth at whitecape.org> writes:

> Tessellation evaluation shaders work almost identically to vertex

> Geometry shaders really are the special case, where multiple
> EmitVertex() calls trigger URB writes in the middle of the program.
