<p>Hi,</p>
<p>We did submit some SPARC patches to make RTEMS compile with LLVM
during May. One of the patches which was not accepted I believe
Sebastian updated and pushed during end of July. We have not made
any attempts rebuilding since. At the time we ran the tests we
were able to run most of the RTEMS test-suite with 20-25 failures
or so if I recall correctly. However most of them was not
dependent on LLVM and fixed since in the RTEMS repository, the
others were fixed in the LLVM SPARC/LEON-REX backend. I recall
that there were some potential problems with SPARC inline assembly
in some cases when building for LEON-REX (no surprise since it is
not the same ISA..). Also, we built newlib using LLVM. I'm not
sure which kernel configurations we compiled for though.<br>
</p>
<p>Since May we distribute a LLVM-4.0 toolchain with our bare-metal
environment. During the coming months we plan to release a LLVM
toolchain together with RCC-1.3.x. However we have some work to do
on the front-end for RTEMS first and testing of course. We will
have some LLVM specific documentation once released.<br>
</p>
Regards,<br>
Daniel<br>
