Description

WASI has no concept of a "process", and the current WASI Core has had most parts that depend on this concept removed already, but a few bits remain: __WASI_CLOCK_PROCESS_CPUTIME_ID, proc_exit, and proc_raise.

For proc_exit and __WASI_CLOCK_PROCESS_CPUTIME_ID, one option is to change them from "process" to "store". Implementations which don't wish to support __WASI_CLOCK_PROCESS_CPUTIME_ID may return an error code from __wasi_clock_time_get, __WASI_EINVAL, instead.

proc_raise probably makes sense to remove regardless, since there is no other support for signal handling.

For reference, in wasi-sysroot, __WASI_CLOCK_PROCESS_CPUTIME_ID is used in C functions clock (C standard), times (POSIX), and getrusage (POSIX).

Research direction

Start by reviewing the remaining WASI Core definitions for __WASI_CLOCK_PROCESS_CPUTIME_ID, proc_exit, and proc_raise, then inspect their uses in wasi-sysroot, including clock, times, and getrusage. The work is done when the process-dependent definitions and uses have a settled, consistent treatment and unsupported clock behavior is specified.
