* cooker updates spilling all over the placeStefano Brivio2023-05-0215-283/+677
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Only tangentially related: - make seitan C99 again, so that I can build cooker without warnings - make Makefiles make use of the usual conventions about assigning directory paths in variables, drop numbers.h as requirement for cooker and make it convenient to run stand-alone Makefiles - fix up nr_syscalls.sh to be POSIX, otherwise it will give syntax errors on my system - define a single, common way to refer to offsets in gluten, and functions to use those offsets in a safe way. Immediates are gone: cooker will write any bit of "data" to the read-only section - call const what has to be const - define on-disk layout for gluten - add OP_NR (to check syscall numbers), rename OP_COPY_ARGS to OP_LOAD (it loads _selected_ stuff from arguments) As for cooker itself: - drop ARG_ and arg_ prefixes from struct names, and similar - add/rework functions to build OP_NR, OP_LOAD, OP_CMP, and to write constant data to gluten - add parsing for "compound" arguments, but that's not completely hooked into evaluation for numeric arguments yet Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
