-Notes on program parameters, etc.
-
-The instructions we emit will use six kinds of source registers:
-
- PROGRAM_INPUT - input registers
- PROGRAM_TEMPORARY - temp registers
- PROGRAM_ADDRESS - address/indirect register
- PROGRAM_SAMPLER - texture sampler
- PROGRAM_CONSTANT - indexes into program->Parameters, a known constant/literal
- PROGRAM_STATE_VAR - indexes into program->Parameters, and may actually be:
- + a state variable, like "state.fog.color", or
- + a pointer to a "program.local[k]" parameter, or
- + a pointer to a "program.env[k]" parameter
-
-Basically, all the program.local[] and program.env[] values will get mapped
-into the unified gl_program->Parameters array. This solves the problem of
-having three separate program parameter arrays.
