This patch adds that information to their > definitions in aarch64-cores.def. Both cortex-a53 and cortex-a57 can be configured without crypto support. The behavior of -mcpu=cortex-a5[37] should be to assume the presence of crypto, we will need to add support for -mcpu=core+feature in the future in order to provide a mechanism to turn off crypto. I think this patch is OK and should go in now. /Marcus

Hi all, The Cortex-A53 and Cortex-A57 cores support the CRC32 and Crypto extensions to the ARMv8-A architecture. This patch adds that information to their definitions in aarch64-cores.def. Tested aarch64-none-elf with no regressions. Ok for trunk? (or next stage1)? Thanks, Kyrill 2014-01-16 Kyrylo Tkachov <kyrylo.tkachov@arm.com> * config/aarch64/aarch64-cores.def (cortex-a53): Specify CRC32 and crypto support. (cortex-a57): Likewise. (cortex-a57.cortex-a53): Likewise.
