Hi gcc-patches group,

Please find the basic patch for adding -mcpu=vulcan support in the gcc.
Broadcom's vulcan is an armv8-a aarch64 based server processor.

At present we are using schedule model of cortex-a57 but soon we will
be submitting a schedule model for vulcan.

Please review the patch (attached with this mail) and kindly merge it
in the gcc-6-branch.

Tested the patch with aarch64-linux-gnu cross build,
aarch64-unknown-linux-gnu native build and make check.
We have also obtained company wide agreement with FSF for contributing
to gcc project.

Thanks.


ChangeLog:
* config/aarch64/aarch64-cores.def (vulcan): New core
* config/aarch64/aarch64-tune.md: Regenerate
* doc/invoke.texi (AARCH64/mtune): Document vulcan as an available option.



with regards,
Virendra Pathak
