Combiner

Description
Tests behavior of NV097_SET_COMBINER_* and NV097_SET_SPECULAR_* final combiner operations.
Suite class def

ColorAlphaIndependence

Demonstrates that setting color on a combiner register does not affect alpha.

Flags

Tests behavior of specular_add_invert_r0, specular_add_invert_v1, and specular_clamp on final combiners.

Independence

Demonstrates that setting a register's value in a combiner stage does not mutate the value until after it is assigned as an output. The test performs several draws where R0 is initialized to some color then both mutated and copied into R1, demonstrating that the original value of R0 is copied into R1 before being replaced with the new value.

Mux

Tests behavior of the "MUX" combiner mode, in which R0.a is used to select between the AB and CD outputs.
