[ARM] Add support for ARM Cortex-R52 processor
2017-07-14 Thomas Preud'homme <thomas.preudhomme@arm.com>
gcc/
* config/arm/arm-cpus.in (cortex-r52): Add new entry.
(armv8-r): Set ARM Cortex-R52 as default CPU.
* config/arm/arm-tables.opt: Regenerate.
* config/arm/arm-tune.md: Regenerate.
* config/arm/driver-arm.c (arm_cpu_table): Add entry for ARM
Cortex-R52.
* doc/invoke.texi: Mention -mtune=cortex-r52 and availability of fp.dp
extension for -mcpu=cortex-r52.
