Hi all,

This patch adds '-mcpu' options for following CPUs:
Cortex-M35P, Cortex-A77, Cortex-A76AE.

Related specifications are as following:
https://developer.arm.com/ip-products/processors/cortex-m
https://developer.arm.com/ip-products/processors/cortex-a

Bootstraped/Regtested for arm-none-linux-gnueabihf.

Please help to check.

Cheers
Dennis

gcc/ChangeLog:

2019-07-29  Dennis Zhang  <dennis.zhang@arm.com>

	* config/arm/arm-cpus.in: New entries for Cortex-M35P,
	Cortex-A76AE and Cortex-A77.
	* config/arm/arm-tables.opt: Regenerated.
	* config/arm/arm-tune.md: Likewise.
	* doc/invoke.texi: Document the added processors.

The patch is ok. The ChangeLogshould list each new cpu entry as a 
separate entity.

I've adjusted the ChangeLog to:

2019-08-23  Dennis Zhang <dennis.zhang@arm.com>

     * config/arm/arm-cpus.in (cortex-m35p): New entry.
     (cortex-a76ae): Likewise.
     (cortex-a77): Likewise
     * config/arm/arm-tables.opt: Regenerate.
     * config/arm/arm-tune.md: Likewise.
     * doc/invoke.texi (ARM Options): Document cortex-m35p, cortx-a76ae,
     cortex-a77 CPU options.

and committed it to trunk for you with r274845.

Thanks for the patch!

Kyrill

Thanks a lot Kyrill!
I will bare this in mind for future patches.
