Hi, I would like to force accesses to some memory variables in a specific mode. For example, I would like GCC to access a 16-bit wide hardware register always in HImode when using a 16bit wide bitfield struct... Currently, GCC can accesses part of this memory structure using QImode, which is not always permitted. Is there a way to do it using an attribute ? Or perhaps another way ? If a target specific attribute must be defined, what should it control, and how to recognized it in my backend ? Thanks, Aurélien
