Hello Sebastian,
That seems like a good idea.
Thanks,

Recently support for LEON3 specific instructions were added to GCC.
Make this support available for RTEMS.
This patch should be committed to GCC 4.9.

Now that muser-mode is default the multilib definitions does not require to
specify that switch any more. Add UT699 to multilib after recent patches. Add
AT697F multilib since there are many LEON2 users running RTEMS.

OK for whichever branch(es) you deem appropriate.

The LEON3/4 soft-core CPU has support for both SPARCv7 and SPARCv8 that
is configurable at design time. The majority of the LEON3 ASICs are v8
compatible, however when designing an as small LEON3 as possible, v7
without FPU is frequently used.
The current GCC leon3 support implies the SPARCv8 inst
. If switching to mcpu=leon3 in RTEMS BSP, then we no longer support the LEON3 V7 processors.

V8 instructions to check that I haven't broken anything. The instructions generated in the
both cases are good, and the RTEMS single-core test-suite runs on both GR712RC and NGFP hardware successfully (apart from the already known two failures of course).

Do you mean the ChangeLog? If so, contrib/mklog will generate a skeleton but
you'll still need to write the decription sentences.
Perfect, thanks!
