Welcome and thanks for considering RTEMS.

Having the code compile on clang would be welcome. I assume this aspect 
of the task would relate specifically to RTEMS code changes. Is this 
correct ?

MacOS support for gcc tools is provided by the RTEMS Source Builder 
(RSB). The details are ..

I would welcome support for clang. Is this enough for a SOCIS project ? 
If clang needs changes for RTEMS then this would start to look like a 
sizable task.

Do we need a specific clang build for each RTEMS architecture ?
Does clang handle the multilib configurations RTEMS needs ?
Which backends are considered stable and worth looking at ?

There are efforts underway for the Cortex-A9. This is happening in the 
xilinx-zynq bsps. This is a due core device so SMP is being worked on 
here. FYI I have OpenOCD working with the A9.

Nice. I run MacOS and FreeBSD and keep the tools updated on both using 
the RSB. It is nice to see other MacOS users entering the community.
