Hi,
Kindly find the Broadcom's Vulcan -mcpu patch (attached) after fixing
the alphabetical order for listing the processor name.
The patch is based on gcc-6-branch.
gcc/ChangeLog:
Virendra Pathak <virendra.pat...@broadcom.com>
* 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.
Thanks.
with regards,
Virendra Pathak
