Hi ARM maintainers,
Any plan to support CTR_EL0.DIC and CTR_EL0.IDC in GCC?
I saw it has been supported in linux mainline(on Mar 7),
Patch link:
http://lists.infradead.org/pipermail/linux-arm-kernel/2018-March/565090.html
Kernel link:

Do you mean implementing the data cache clearing elision in __clear_cache as
discussed in June [1]?
I am not aware of any plans to implement that support yet as we'd need hardware
to test this properly on.
If you can implement and test it and post it to the list I'm sure the
maintainers would be happy to review such patches though.
Thanks,
Kyrill

This patch adds HiSilicon's an mcpu: tsv110, which supports v8_4A.
It has been tested on aarch64 and no regressions from this patch.
This patch is OK for Trunk.
Do you need someone to commit it on your behalf?
Thanks,
James
