  "message": "Save memory allocation in the elf loader\n\nThe current elf loader uses too much memory. For example, I have a\nexecutable with a bss section of 400 MB and I set the ram size to 512\nMB. Qemu uses about 780MB of RAM (which is fine), but there\u0027s a peak at\n1.6 GB during initialization (this is not fine).\n\nThis patch fixes two things:\n 1) do not allocate each elf program twice.\n 2) do not allocate memory for areas that are only zeros.\n\nFor this we need a new field in Rom: \"datasize\" which is the size of the\nallocated data. If datasize is less than romsize, it means that the area\nfrom datasize to romsize is filled with zeros.\n\nSigned-off-by: Fabien Chouteau \u003cchouteau@adacore.com\u003e\nSigned-off-by: Alexander Graf \u003cagraf@suse.de\u003e\n",
