Hi,

We have decided to backport this patch to add multilib support for ARM Cortex-M23 and Cortex-M33 to our embedded-6-branch.



*** gcc/ChangeLog ***

2016-11-30  Thomas Preud'homme  <thomas.preudho...@arm.com>

        * config/arm/t-rmprofile: Add mappings for Cortex-M23 and Cortex-M33.


Best regards,

Hi,

With ARM Cortex-M23 and Cortex-M33 and the support for RM profile multilib added recently, it's time to add the corresponding CPU to architecture mappings in config/arm/t-rmprofile. Note that Cortex-M33 is mapped to ARMv8-M Mainline because there is no transitive closure of mappings and the multilib for ARMv8-M Mainline with DSP extensions is ARMv8-M Mainline.

ChangeLog entry is as follows:

        * config/arm/t-rmprofile: Add mappings for Cortex-M23 and Cortex-M33.


Testing: Linking fails before this patch when targeting one of these two cores and using rmprofile multilib but succeeds with the patch.

Is this ok for stage3?

Best regards,

Thomas
