Does it make sense to build RTEMS without the RTEMS thread model
enabled?
IMO, it doesn't nor do I think it makes sense to build RTEMS with
--disable-posix.
However, in the past, there had been strong resistance to make threading
the default or mandatory. because of the overhead it causes in RTEMS.
The RSB and the RPM build infrastructure always uses the
"--enable-threads" option.
I believe, hardly anybody has used a thread-disabled rtems-GCC for many
years nor have such thread-disabled GCCs seen much testing with RTEMS
and in GCC in general.
Why don't we make this to the default?
You'd have to ask those who have been fighting this. I am all for it.
