--- Comment #4 from Ilia Mirkin <imirkin at alum.mit.edu> ---
I'm going to tentatively say that the issue lies outside of i965 -- with
nouveau I see 2 geometry shaders generated, one for points, one for lines.

GEOM
PROPERTY GS_INPUT_PRIMITIVE LINES
PROPERTY GS_OUTPUT_PRIMITIVE TRIANGLE_STRIP
PROPERTY GS_MAX_OUTPUT_VERTICES 6
PROPERTY GS_INVOCATIONS 1
DCL IN[][0], POSITION
DCL IN[][1], PRIM_ID
DCL IN[][2], GENERIC[0]
DCL IN[][3], GENERIC[2]
DCL IN[][4], GENERIC[4]
DCL OUT[0], POSITION
DCL OUT[1], PRIM_ID
DCL OUT[2], GENERIC[0]
DCL OUT[3], GENERIC[1]
DCL OUT[4], GENERIC[2]

vs

GEOM
PROPERTY GS_INPUT_PRIMITIVE POINTS
PROPERTY GS_OUTPUT_PRIMITIVE TRIANGLE_STRIP
PROPERTY GS_MAX_OUTPUT_VERTICES 6
PROPERTY GS_INVOCATIONS 1
DCL IN[][0], POSITION
DCL IN[][1], PRIM_ID
DCL IN[][2], GENERIC[0]
DCL IN[][3], GENERIC[1]
DCL IN[][4], GENERIC[2]
DCL OUT[0], POSITION
DCL OUT[1], PRIM_ID
DCL OUT[2], GENERIC[0]
DCL OUT[3], GENERIC[1]
DCL OUT[4], GENERIC[2]

Both of those should be getting GENERIC[0..2] on the inputs. So either st/mesa
and i965 have the same bug, or it's getting messed up by the linker.
