When coming directly from glsl_to_nir (rather than via TGSI where
information about, for example, mat4's is lost), both const_index
fields will be used (vs. tgsi_to_nir where the 2nd is always zero).
For example:
decl_var uniform INTERP_QUALIFIER_NONE mat4 ModelViewProjectionMatrix (0, 0)
decl_var uniform INTERP_QUALIFIER_NONE mat4 NormalMatrix (4, 4)
...
vec4 ssa_54 = intrinsic load_uniform () () (4, 0) /* NormalMatrix
*/
vec4 ssa_56 = intrinsic load_uniform () () (4, 1) /* NormalMatrix
*/
vs:
decl_var uniform INTERP_QUALIFIER_NONE vec4[8] uniform_0 (0, 0)
...
vec4 ssa_54 = intrinsic load_uniform () () (4, 0)
vec4 ssa_56 = intrinsic load_uniform () () (5, 0)
