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.zh...@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.
