/* Indices for named (non-XFB) varyings that are present. These are packed
|
|
* tightly so they correspond to a bitfield present (P) indexed by (1 <<

|
|
* of a given special field given a shift S by:
|
|
*
|
|
* idx = popcount(P & ((1 << S) - 1))
|
|
*
|
|
* That is... look at all of the varyings that come earlier and count them, the
|
|
* count is the new index since plus one. Likewise, the total number of special
|
|
