* Makefile.ctr: enable gc-sections This frees ~160k of RAM without any downsides that I know of. It's not much, but helps pcsx_rearmed on old3ds where it barely fits in RAM. * remove some dupe logic Regardless if `save_state_in_background` is enabled or not, it does exactly the same so the check can be removed. * optimize RAM state load content_load_state_from_ram() doesn't need the backup copy, content_save_state() never touches the ram_buf. It seems the whole logic was copy-pasted from content_undo_load_state() without thinking. * avoid useless memory use and copying Just take the source pointer instead of making a copy and then freeing it. This is a big deal on slow platforms having to deal with large states, like psx on old3ds. * allow the core to disable the savestate undo feature The undo feature may amount to at least 4 simultaneous buffers: save undo, load undo, the current save/load buffer, temporary buffer. When emulating a system with relatively large states on a system with little RAM (like PSX on old3ds) that amounts to something like ~18MB of ~42MB available to the core. Under memory pressure the libctru variation in RetroArch tries to salvage some memory from the main stack and linear memory, but since those are variable, they start to overlap creating instability. The solution is to just disable the undo feature.
