That's what (essentially) happens here. The CONST_DECL is wrapped up in a VIEW_CONVERT_EXPR to array type and a component with non-constant index is extracted from it. > So - if you can burn some extra cycles to figure out why it's not > replaced by its DECL_INITIAL ...? We specifically prevent that in gigi because it will need to be spilled to memory given the above access pattern, so I don't really see the problem. Here's the access in .optimized: _38 = MEM[symbol: pkg__zero_unit, index: ivtmp.38_27, step: 4, offset: -4B]; -- Eric Botcazou
