Not recently. It needs to be resynced against the source tree. Usually the
main thing is to account for new/modified headers which impact the
scheduler simulator infrastructure or the "port".
The biggest issue I think is faced now is that RTEMS depends more
on newlib BSD extensions than it did when the simulator was written.
The last person who attempted to update it was a GSoC student who
couldn't get it to build against glibc. The approach to work through
that has historically been to provide the missing .h files in the scheduler
simulator -- copy them. But I think the BSD code in newlib .h files is
now more intertwined rather than extra .h files. I would suggest a
building a native Linux toolset with newlib instead of glibc and using
that as the compiler for the scheduler simulator. It doesn't need much
native support beyond stdio.
