10 years agoglsl: Skip loop-too-large heuristic if indexing arrays of a certain size

glsl: Skip loop-too-large heuristic if indexing arrays of a certain size

A pattern in certain shaders is:

   uniform vec4 colors[NUM_LIGHTS];

   for (int i = 0; i < NUM_LIGHTS; i++) {
      ...use colors[i]...
   }

In this case, the application author expects the shader compiler to
unroll the loop.  By doing so, it replaces variable indexing of the
array with constant indexing, which is more efficient.

This patch extends the heuristic to see if arrays accessed within the
loop are indexed by an induction variable, and if the array size exactly
matches the number of loop iterations.  If so, the application author
probably intended us to unroll it.  If not, we rely on the existing
loop-too-large heuristic.

Improves performance in a phong shading microbenchmark by 2.88x, and a
shadow mapping microbenchmark by 1.63x.  Without variable indexing, we
can upload the small uniform arrays as push constants instead of pull
constants, avoiding shader memory access.  Affects several games, but
doesn't appear to impact their performance.

glsl: Lower constant arrays to uniform arrays.

Consider GLSL code such as:

   const ivec2 offsets[] =

              ivec2(1, -1),  ivec2(1, 0),  ivec2(1, 1));

   ivec2 offset = offsets[<non-constant expression>];

Both i965 and nv50 currently handle this very poorly.  On i965, this
becomes a pile of MOVs to load the immediate constants into registers,
a pile of scratch writes to move the whole array to memory, and one
scratch read to actually access the value - effectively the same as if
it were a non-constant array.

We'd much rather upload large blocks of constant data as uniform data,
so drivers can simply upload the data via constbufs, and not have to
populate it via shader instructions.

This is currently non-optional because both i965 and nouveau benefit
from it, and according to Marek radeonsi would benefit today as well.
(According to Tom, radeonsi may want to handle this itself in the long
term, but we can always add a flag when it becomes useful.)
