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
* 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.
