[Mesa-dev] [PATCH 03/17] mesa: rework ParameterList to allow packing

Timothy Arceri tarceri at itsqueeze.com
Sun Jun 25 01:31:35 UTC 2017


Currently everything is padded to 4 elements. Making the list
more flexible will allow us to do uniform packing.

This change requires us to remove the existing packing in
_mesa_add_typed_unnamed_constant() in order to avoid regressions.
This packing will no longer be required once we add full packing
support in the folling patches anyway.
