11 daystools/nolibc: implement wait() in terms of waitpid()Thomas Weißschuh
Newer architectures like riscv 32-bit are missing sys_wait4(). Make use of the fact that wait(&status) is defined to be equivalent to waitpid(-1, status, 0) to implement it on all architectures.

11 daystools/nolibc: fall back to sys_clock_gettime() in gettimeofday()Thomas Weißschuh
Newer architectures (like riscv32) do not implement sys_gettimeofday(). In those cases fall back to sys_clock_gettime(). While that does not support the timezone argument of sys_gettimeofday(), specifying this argument invokes undefined behaviour, so it's safe to ignore.

11 daystools/nolibc: include nolibc.h early from all header filesThomas Weißschuh
Inclusion of any nolibc header file should also bring all other headers. On the other hand it should also be possible to include any nolibc header files in any order. Currently this is implemented by including the catch-all nolibc.h after the headers own definitions. This is problematic if one nolibc header depends on another one. The first header has to include the other one before defining any symbols. That in turn will include the rest of nolibc while the current header has not defined anything yet. If any other part of nolibc depends on definitions from the current header, errors are encountered. This is already the case today. Effectively nolibc can only be included in the order of nolibc.h. Restructure the way "nolibc.h" is included. Move it to the beginning of the header files and before the include guards. Now any header will behave exactly like "nolibc.h" while the include guards prevent any duplicate definitions.

2025-04-22tools/nolibc: implement waitpid() in terms of waitid()Thomas Weißschuh
