[arm-embedded][PATCH] Add multilib mapping for -mcpu=cortex-r52

- Subject: [arm-embedded][PATCH] Add multilib mapping for -mcpu=cortex-r52
Hi,
Currently -mcpu=cortex-r52 gets assigned the default multilib due to
lack of mapping from -mcpu=cortex-r52 to an -march option. This is
inconsistent with -march=armv8-r which gets the thumb/v7-ar multilib.
This patch adds the appropriate mapping.
ChangeLog entry is as follows:
*** gcc/ChangeLog.arm ***
2018-03-15 Thomas Preud'homme <thomas.preudhomme@arm.com>
* config/arm/t-rmprofile: Add mapping from -mcpu=cortex-r52 to
-march=armv7.
Testing: -mcpu=cortex-r52 -print-multi-directory prints . (ie. default
mutlilib) without the patch with a multilib build but prints the
expected thumb/v7-ar with the patch.
We've decided to apply this patch to the ARM/embedded-7-branch.
Best regards,
Thomas
