From 2376caf911f027b072c236b6a91f152a7ffe4f67 Mon Sep 17 00:00:00 2001 From: Thomas Preud'homme Date: Fri, 14 Jul 2017 15:26:19 +0000 Subject: [PATCH] [ARM] Add support for ARM Cortex-R52 processor 2017-07-14 Thomas Preud'homme 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.
