I see this patch is for master. Is a gcc 12 patch available so I can test it?
The patch works also for GCC 12. I only did a test run of the RTEMS tests.
It failed to apply for me with the gcc-12 for rtems6. The configure pieces did

Hi,
Please find the latest report on new defect(s) introduced to RTEMS found
with Coverity Scan.
2 new defect(s) introduced to RTEMS found with Coverity
Use CLOCK_REALTIME and CLOCK_MONOTONIC for relative thread queue timeouts
instead of CLOCK_REALTIME_COARSE and CLOCK_MONOTONIC_COARSE. This fixes an
issue with clock_nanosleep() in combination with clock_gettime().
Close #4669.

These allow one to non-destructively iterate over the set or clear bits
in a bitset. The motivation is that we have several code fragments
which iterate over a CPU set like this:
while ((cpu = CPU_FFS()) != 0) {
cpu--;
CPU_CLR(cpu, );
;
}

There is a reference to malloc() in #define __BITSET_ALLOC. Even

malloc() and prevent their use (including in macro definitions).

We have a couple optimizations for when the bitset is known to be just

to determine the size than just to do the necessary computation. Now,
