/* On Valhall, the driver gives the hardware a table of resource tables.
* Resources are addressed as the index of the table together with the index of
* the resource within the table. For simplicity, we put one type of resource
* in each table and fix the numbering of the tables.
*
* This numbering is arbitrary. It is a software ABI between the
* Gallium driver and the Valhall compiler.

/* Indices for named (non-XFB) varyings that are present. These are packed
