I added the support for aarch64 to systemtap. It significant work to add
architecture support for a new platform.  We welcome outside patches to support
new architectures, but it is unlikely that we are going to develop one for
SPARC.  One could use the changes in systemtap for aarch64 as suggestions of
where changes need to be made to support a new architecture:

https://sourceware.org/git/?p=systemtap.git&a=search&h=HEAD&st=commit&s=aarch64

In the kernels sparc has HAVE_KPROBES in linux/arch/sparc/Kconfig, so kprobes
are implemented.  However, I don't know have tested that is. I found some
issues with the aarch64 implementation of kprobes when working on the systemtap
aarch64 support.

Dear good brother,are you the developer of systemtap?Can you add the support of
sparc?Thank you very much!
I read the source of tapset and runtime,i think we can add the register.h and
stp files to support a new architecture.
I know it support aarch64(i already use),but what i say is sparc.

Thank you very much!love you!

Systemtap does not currently support SPARC processors. It is unlikely that
SPARC support will be added by myself or others developers at Red Hat. However,
we welcome contributions from outside developers.  Information about working on
systemtap is available at:

Jose E. Marchesi mentions a port of systemtap to SPARC on
http://www.jemarch.net/cv.html .  Maybe those patches can be posted and that
can be used as a starting point for SPARC support and further developed by
people using SPARC Linux systems.

Don't have any access to SPARC machines, so it is unlikely that we will be able
to address this.
