Hello,
The Cortex-A72 is an ARMv8 core with the same architectural features as the
Cortex-A57. This patch adds support for the command line option
-mcpu=cortex-a72 with the same effect as the -mcpu=cortex-a57 option, with
only the name being different. It also adds support for the
-mcpu=cortex-a72.cortex-a53 big-little variant.
Tested with check-gcc for arm-none-linux-gnueabihf. Tested the new cpu
options from the command line.

* config/arm/arm-cores.def: Add cortex-a72 and
cortex-a72.cortex-a53.
* config/arm/bpabi.h (BE8_LINK_SPEC): Likewise.
* config/arm/t-aprofile (MULTILIB_MATCHES): Likewise.
* config/arm/arm-tune.md: Regenerate.
* config/arm/arm-tables.opt: Add entries for "cortex-a72" and
"cortex-a72.cortex-a53".
* doc/invoke.texi (ARM Options/-mtune): Likewise.
This is OK - it's purely wiring up a new name and treating that the
same as an existing tune. No new functionality and no point in waiting
for a year for this cpu option to be available for folks.
On Matthew's (offline) request, I've installed this as r220399 with the
following minor change:
I guess we now need the wwwdocs changes.html update for arm and aarch64
to let users know.

Split this long line:

+@samp{cortex-a72.cortex-a53}.
As so.
