Falkor is an ARMV8-A part, but also includes the RDMA extension from ARMV8.1-A.
I'd like to enable support for the RDMA instructions when -mcpu=falkor is used,
and also make the RDMA intrisics available. To do that, I need to add rdma
as an architecture extension, and modify a few things to use it. Binutils
already supports rdma as an architecture extension.
I only did the aarch64 port, and not the arm port. There are no supported
targets that have the RDMA instructions and also aarch32 support. There are
also no aarch32 RDMA testcases. So there is no way to test it. It wasn't
clear whether it was better to add something untested or leave it out. I chose
to leave it out for now.
I also needed a few testcase changes. There were redundant options being
added for the RDMA tests that I had to remove as they are now wrong. Also
the fact that I only did aarch64 means we need to check both armv8-a+rdma and
armv8.1-a for the rdma support.
This was tested with an aarch64 bootstrap and make check. There were no
regressions.
OK?
Jim
