Hi Eric,
so I've been playing around with gallium/ubos a bit more,
I noticed something I wasn't sure abuot between the i965 vs and fs backends
FS does
ir_constant *offset = ir->operands[1]->as_constant();
fs_inst *pull = emit(fs_inst(FS_OPCODE_PULL_CONSTANT_LOAD,
packed_consts,
surf_index,
fs_reg(offset->value.u[0])));
so it gets offset and derefs it later,
ir_constant *const_offset_ir = ir->operands[1]->as_constant();
unsigned const_offset = const_offset_ir ? const_offset_ir->value.u[0] : 0;
does a check around it.
What are the different ways ubo_load can get used? I think I need to
create a tgsi IR equivalent of it, since I don't think I can resolve
the offset into the constant buffer at the glsl->tgsi translation
stage.
Dave.
