charset="us-ascii" Content-Transfer-Encoding: 7bit Errors-To: ltp-bounces+ltp=archiver.kernel.org@lists.linux.it Sender: "ltp" The problem we have at the moment is that all syscalls input files must be changed by hand each time we need to test a new syscall. The idea is to simplify this process, providing a script that is able to read from kernel sources and to generate all syscalls files we need. This patch set adds a new command inside the syscalls folder and it refactors the previous regen.sh code. The new way we have to generate the syscalls.h file is the following: include/lapi/syscalls/generate_arch.sh path/to/kernel/source include/lapi/syscalls/generate_syscalls.sh path/to/syscalls.h Scripts are independent and they can be run separately. generate_syscalls.sh is the equivalent of regen.sh, but its code has been cleaned up.
